Motherhood – The world’s most beautiful feeling, and today I am one of those blessed ones who can enjoy this experience.
I am Sharvari, a Software engineer at ISL, a caring mother and a responsible wife at home.
Too many roles and only 24 hours in a day, you need to be on your toes to manage everything. This juggling act demands expertise, patience and hard work.
It’s always a difficult situation for first time mothers like me to balance both professional and personal duties. They will always end up with a feeling that they have not achieved enough.
Moreover every working mom would want to give her best to her new born when she is at home and as a responsible individual you would also want to give best at work.
The key that I found in such a situation is “Effective Time Management”.
This starts from planning, one might have to plan for every small and big thing which may include planning your day properly or even planning for future.
My experience is you have to learn the 4Ds of time management–
Do it – Get it done the sooner the better.
Delegate it – It needs to be done but someone else can take care of it
Dump it – Anything that is unimportant now and in the future dump it.
Defer it – This needs to be done but not now it can wait.
Most, if not all the activities in a day can be put in these categories.
These are just a few pointers which can help you towards effective time management.
This is a learning task, and I am still learning how I can manage my time effectively to be a better mother and a better individual.
Finally, also remember to keep some time for yourself.
It is difficult to find "me time", a necessary and needed moment to refresh and regroup, while managing other things.
Work hard and smart and the world will be yours!
Fresh out of college, after years of studying the core subjects, each one of wish to create something new and exciting. Develop that code which is highly appreciated, solves the problems, is extremely efficient etc etc.
But not all of us get to develop the main source and even be a part of that development cycle in industry. So, should you be unhappy on the testing role offered? Absolutely not!
Testing is a very responsible job. No product goes into the market unless it is thoroughly tested and gets the approval of the tester that it is good to go. This role is not easy and can be very interesting. As a tester, you know the behaviour of the software more than the developer himself. You are the first client. Testing the real time scenarios, you are a bridge between the market and the development. Trust me, it is very exciting.
So, how should you go about testing?
Here are some tips on better testing:
1. Understand what is to be tested.
Know the software thoroughly. Go through the document given by the developer.
2. Ask for more.
Discuss with developer about the software's behaviour, its implementation etc. The more you involve in it, the more bugs you can find.
3. Plan your tests.
Write down the plan of the tests. This should list all the tests. Be sure to do negative testing. Often, software works in normal cases. But goes for a toss in negative conditions. Include real time scenarios, customer situations. Think like a customer.
4. Implement your tests.
Choose an efficient testing tool or language. Plan your implementation well. Remember, tests should be as efficient as the main code you are testing. This is the most interesting part. Here, you get to do automation around the software, learn new products. Can be innovative as well!!
5. Identify the bugs.
Writing tests is not all. You need to understand the erring cases, identify the defects. Get them fixed. Critical defects are highly appreciated, because you are catching them before the software goes in market. This actually saves alot!
6. Get the bugs fixed.
Let the developer fix the defect. Re-test the fixed code. Feel free to say NO, if you are not happy.
Testing is really a responsible job role. Be proud to say you assure the quality of the software to be delivered!
Meet Kalpana, the immense source of inspiration at IBM India Software Lab. Kalpana has a rich pool of experience and has a calm demeanor, even on her busiest days! Director at IBM ISL and a mother to her 24 year old son, Kalpana integrates work and family beautifully while ensuring she gets out for a walk and enjoy mystery novels to de-stress.
Kalpana is passionate about contributing to women's growth in technical field and she extended her warm support to talk to us and provide encouragement to be positive, brave and above all..happy! Read her interview to know more.
Thank you Kalpana for opening the group with your valuable words.You are certainly our pillar of strength!
An introduction: Professional background, family, interests
I have 29+ years of industry experience and have been with IBM for last 19 years. I have been with India Software Lab(ISL) since its inception in 2001 and have played key leadership roles across functions in growing the lab to its current level.
Born and brought up in Bangalore, I have completed my Masters Degree in Engineering from the Indian Institute of Science, Bangalore in 1982, after which I embarked on an 11-year career with PSI Data Systems.
Family - I am married to a Chartered Accountant, have a son who is 24 years old and stay with my extended family which includes my mother-in-law.
I like listening to old hindi music and read a lot and mostly fiction.
What made you choose a career in technology? Can you explain how you guided your career to be where you are today?
When I was in doing my undergraduate degree, I had a friend who was always talking about a post-graduate degree course in Engineering in the premier Indian Institute of Science (IISc) at Bangalore and that she was applying for it. So I just went along, took the entrance test, got through it and joined the Bachelor’s course in Electrical and Electronics Engineering. I also went on to do my Masters in Engineering from IISc itself. Thereby, a chance discussion and a lot of encouragement and support from my parents, my father in particular, took me along this path and here I am enjoying a career in technology!
How have you balanced your professional and personal demands simultaneously?
I like the current term a lot better - "Work Life Integration" than the work life balance. It has been a challenge given that we work in a global company. I try to keep the week-ends for my family and be there for important events or testing times. I ensure I am there when I am most needed. The flexibility work options provided by IBM are useful. I also built a good team with the team members having a strong mutual trust - this team contributes to each one managing work and life.
Our health tends to take a back seat due to work and personal commitments. What are your suggestions for nutrition and fitness?
I believe that if the woman in the house stays fit and healthy, she can then ensure the others are healthy too. Health is one area where we must lead by example. Personally, I try and make time for walking, and I try to walk a lot! Also, have been interested in Yoga and have picked it up in the last couple of years.
Any advice on women who choose to pursue a career in technology?
Given our education and experience we have the skills to take up a career and be successful. But the challenge has been on who we think is responsible for our career. Personally I feel we are equally responsible as our manager and the organization. But first and foremost we have to decide “to want a career” and learn to look at work as not a physical place but a state of being, of integration with our regular flow of daily life. Career in technology is great place to be today - given the changes that are happening and how much technology is influencing our daily lives and also the various business. Opportunities are many. Go for it.
In addition, Focus on Personal Excellence, never be satisfied with what you know, Integrity, Positive Attitude are important; try to maintain good relationship with people you work with; Never hesitate to ask someone to teach you what you want to learn and keep continuously learning.
An Indian way to say Hello with dignity, respect and love to everyone.
This is my first post here at developerette and I am quite excited about it. I really hope that typing here is completely a unique experience and more exposure to learn more. So am here.. doing some shadow postings here & there as well as writing something unique here & there.
Hope to have a good learning experience here :)
Please welcome Dr. J.Manjula, principal, GVG college for women, Udumalpet, Tamil Nadu. Dr. Manjula is a strong willed and courageus woman, on whose shoulders rests the ambition of the girls at GVG. She's a spirited professional, dedicated to her work, the well being of her staff and the future of her students. Above all, she is a progressive leader, who believes that nothing can empower the women of this country more than solid education and well defined career paths.
We are honored to have Dr Manjula speak to us about her powerful personal life, her devotion to the college and her advice to girl students across the country. Please read on.
Thank you ma'am for sharing your experiences with us, you lead by example in your personal and professional life, thus encouraging girl students and women IT professionals from all backgrounds.
Please tell us about your work and about your personal interests:
Of the 35 years I've been associated with GVG, I've been the principal for the last 12 years. There are various achievements i'm proud of at GVG. Last year we crossed 340 placements. We were the first to get the NAAC accreditation and now have also been ISO certified. We're an autonomous college and so, have the freedom to design our own course curriculum. In the south, we are the leaders in development education and job skills and are enjoying the benefits of that.
Also I was rewarded the Excellence award conferred by the Rotary club. I have a son, who is settled in the States with his family. I am drawn to philosophy and am a member of the Art of Living society and follow Guru Mahan philosophy which provides me a lot of motivation. I devote all my time to the well being of the students, their curriculum, introducing new courses, the food at the hostel and other amenities.
GVG is a college of excellent reputation. How do you maintain that?
The key is the focus on the girls. Even after they go to other countries for higher education, they never forget theor alma mater. We train them on life skills and not merely books. Once they graduate from GVG, the girls are knowledgeable individuals who have strong careers and are excellent home makers. All that is important for women, and we ensure there is plenty of focus on both angles. Various topics of empowerment are discussed with the girls like Cancer, Female Infanticide, Mental and Physical strength etc.
Technology like Campus-i is used to detect, understand and eliminate the root cause of illnesses that are common to this area like anemia. This incomparable focus is what drives parents from faraway towns like Kanyakumari etc to leave their wards in the safety of GVG. Be it hot water, amenities, clean drinking water, activities or studies, there is no compromise on quality.
My aim is to give the best to the girls so they don't feel deprived because of being born in a small town with less opportunities. When they join companies, they are clearly identified as GVGians!
Companies like IBM have contributed greatly by providing opportunities and a stage for success to the students. More interaction from professionals is required for the girls to learn and grow and take up responsible positions in the corporate world.
What are some of the challeges the girls face in building careers in IT and how do you guide them?
The big question is Career or Marriage? My answer is to win at both. I alsways give my example to parents and the girls, that I am a widow, lost my husband in a drowning accident and came out of the tragedy strong and empowered only because of my job. If I did not have a career and the financial indipendance to fall back on, my obstacles would have multiplied manifold. When the doctors declared my husband dead, my first words were, thank God I have a job in my hands and I will survive this. Education is a bigger gift than Gold and parents need to understand that. A job provides financial, mental and emotional well being to a woman.
The other challenge is Communication. The girls here are shy, so we encourage them to face the crowd even if for 2 minutes and speak. The practice on a regular basis, helps them overcome their hesitation.
What is your advice to girls who aspire to succeed professionally?
I was sent to colleges in Haryana and Goa and other cities for mentoring and realised that girls everywhere need to focus on education and jobs rather than getting married first. I believe that we need to help the weaker students by spending time on the areas they are unable to cope with. 0 and 80 are just numbers and I don't criticize for poor performance. If you have the will to learn, the percentages will improve as well.
Values are critical. Be a good human being, that's primary. We do not allow the use of mobile phones and discourage the girls from friendships and relationships which lead them away from education.
Lastly, Make decisions in personal relationships that make your parents and teachers proud.
Meet Sargam Singh, the star at IBM Software Labs who's grown and succeeded by plugging away challenging situations at work and home. Sargam talks about her role at IBM as a Development Manager and at home as a mother and wife in an interview with us.
Thank you Sargam for sharing your mantra with the developerette group. We are certain that your experience will encourage new mothers to not only build careers in IT but also confidently take positions in leadership.
Please tell us about your work: the role you have at IBM, your responsibilities and your team.I have 14+ years of industry experience and have been with IBM for last 7 years. I joined IBM as a Project Lead on WebSphere Application Server Test team. Currently, I am a Development Manager with IBM India Software Labs and am responsible for development and delivery of WebSphere Service Registry and Repository (WSRR) product out of India. Besides this, I lead the Asia Pacific Tech Sales Support for WSRR and am a member of the World Wide Agile Leadership Team.
I manage a team of 11 people, out of which close to 50% are women. It is a very high potential team and I see a good diversity in the top performers. In my opinion, women can bring in a different kind of perspective, and are often able to capture softer aspects of people capabilities which makes them great team player and leaders.
Tell us about your family and how you integrate your work and family?
My husband works with an IT multinational as a Program Manager. Besides us, I have a daughter who is 12 now and my mom-in-law who is with us. Both me and my spouse are in a high pressure jobs but it is the strong family support system which makes managing everything so simple. Coupled with this, IBM's work-life integration culture makes it possible to deliver the best both at work as well as for my family. I make sure that I am available for every important occasion and at any time when my family needs me the most. However, there are challenges at times, when work demands more time and my family has been amazingly supporting, including my little daughter who is growing up to be a responsible teenager.
What are some of the challenges you have had to face to keep both aspects balanced?
There have been times in my career when taking some great opportunities called for a decision which impacted my family. Soon after I joined IBM, I had to leave for US for an extended period of 6 months. I made that decision after a lot of deliberation as it meant leaving my daughter behind for that long. My husband was a big support and stood by me all through. That period was very tough for me but I emerged out of it as a winner, both at personal and professional front. My husband and daughter joined me in US for 2 weeks after my assignment ended and time and distance had in no way impacted my bonding with my daughter. In fact, she looked much more confident and independent. On the professional front, those 6 months provided a boost to my career by opening up newer opportunities.
So this is one such instance, and there are times when we have to make such tough choices. We need to understand this delicate balance and take a call depending on what is more important at that point in time. Opportunities have to be grabbed, and if you want to excel professionally, you need to have your goals defined. Family interest must come first, but women often live in a self created notion that things will break if they are not around. So create a strong support structure and when faced with a challenge which calls for a decision, talk about it to your family and they will be your biggest strength to take it head-on.
Now that you have overcome the initial challenges, what is your advice to young mothers who wish to succeed in their carers?
I feel that single thing which can guarantee success is the "right attitude". I would say two things here -
Firstly, create a strong support structure, both at work and at home. At home, you need to have the confidence that things can go on even when you are away. At work, you have to build a strong team and backup which can stand by you in case of any emergency. Both these are easy to do if you have the right attitude which naturally wins love and support from people around you, be it your family, or colleagues or even a household help.
Secondly, keep your high level goals clear, both on personal and professional front. There will be times when your family needs you more and you cannot let your professional life impact that, and there will be occasions when you will have to sacrifice family time for tackling challenges on work front. The key to success is being able to successfully maintain this delicate balance. Risk Taking choices come every day in everything we do, personal or business, in many forms. It is a matter of having the confidence in your judgements and stand up for what you believe in.
Would you suggest development as a good career for women?
Certainly yes. Women often shy away from technical path for different reasons. However, women have an innate quality of dwelling deep into details of things without loosing sight of the bigger picture. This can play an important role in ensuring a very successful technical career for women. Excellence is a state of mind and it comes naturally to them. Making excellence critical in the small steps can lead to great results for the larger agenda in your personal and work lives.
Hi I am Dhivya from the Team VIVID WINNERS and we got the ALL GIRLS TEAM AWARD in the TGMC'10 contest. Now I am doing Final year IT in Mepco Schlenk Engineering College, Sivakasi. I like to share about our project details. Our project is INFORMATION KIOSK which aimed at developing an information kiosk for Sivakasi (which is in TamilNadu, India) that is of importance to a person to know more information about the city. This system will be more useful for the tourist and the person who is new to the city. It also has some useful links like matrimonial, employment opportunity, e-governance and also e-agriculture. One can also read the daily newspaper. The tourist can view the route from the main bus station in Sivakasi to their desired location. IBM TGMC contest make us to gain more knowledge and we feel proud to share our experience.
My team mate Jothi wants to share the project submission process "We submitted our project as in the format specified by TGMC. And at the time of the submission we didn’t think that we will go this much. But we won the all girls team award . During the face to face evaluation we were really very happy to get a chance to share our experience with IBM TGMC. "
What Kanthimathi and Senbagareka(my team mates) felt when we were there in the felicitation ceremony is "Our Eyes gleamed with surprise when we came to know that we are one among the finalist in the felicitation ceremony . We were inspired by the video played in the begining of the ceremony.The thoughtful speech given by highly experienced people in IBM was awesome.We were out of the world when our names were pronounced in the Felicitation ceremony.That was one of the best moment in our life.And we were very proud to receive the “ALL GIRLS TEAM AWARD”. The price we won is always a memento reminding our great time in DELHI."
I want to thank my guide Prof.T.Revathi who supported us to do this project. She gave us lot of ideas to do this project. She referred the scoring criteria for the project submission and told us to use Ajax, to take backup of the database and to make the website available in the local language too. She also mailed us some reference web pages to do those things. And also she helped us during SRS preparation. She taught us about the OOAD concepts.
I also want to thank our department staff Mr.A.S.Karthik Kannan who gave us some ideas and corrections in our project to make our project the Perfect One. I like to thank Dr.K.Vijayalakshmi and Mrs. S. Kavi Priya who helped us to complete our project on time. I like to thank my entire department Staffs since they all encouraged us to do this project because of that we got energy during our tough time.
It's been seven years now since I entered the IT world and the journey so far has been so eventful that I won't go with common tag line - 'Time just flies......' :)
Setting up yourself and excelling in this competitive world and at the same time balancing your responsibilities at home does demand a lot from you. Every modern girl dream of standing on their own feet and be economically independent. That's the dream one chases for first 20-25years of one's life. I won't deny that, same was my dream too. I completed my Masters in Computer Technology and fortunately got a good break in good IT company. We all know that change is law of nature but the pace with which technology changes is really tuff to catch up with latest. One needs to regularly brush up their skills very frequently and that does demand a good amount of time from you.
So, that was about my professional role, going toward personal me, I am happy to share that despite being daughter and sister, I have the responsibilities of being a wife, daughter-in-law and most importantly mother of two small kids. If one starts counting the responsibilities that comes with that package, it won't be possible. Here, comes in picture what we call in IBM - Work/Life Balance. I would say, the stage I am in right now, is the most crucial and difficult stage. There are challenges in your professional life that you can not leave taking up as well as in personal life that you can not get rid of. There's testing time all through the way. You are being tested for your patience level almost daily. No wonder, we find many cases of Stress and frustrations in such situations. But, the key here is how we sail in these testing times, how we balance out things, how to set a demarcation between professional and personal life and coming out a winner in both area.This is the phase when the most precious thing that you can think is - TIME. One needs to make best use of the time available. Time management is the key. There are some other important skills that comes as good help. These are :
- Delegation of non-important work.
- Focusing on key areas.
- Saying 'No' to things that are really not in your area and you are not willing to go for that.
- Spending some time for self only, when you can do some thinking/planning on course of action you really want to pursue.
- Choosing the right direction.
- Open for brainstorming, discussion with peers, seniors, family whenever you are in delima.

As one of the core developer of DB2 Connect CLI team, I got an opportunity to work on supporting generic special registers feature. Idea behind this blog is to spread some of the benefits and usage to help application development community understand it better to leverage the same.
Though focus of this blog would remain CLI centric, similar concept exists in other client drivers like IBM DB2 .NET provider and IBM JDBC driver (aka JCC).
IBM Data Server Driver configuration file (by default named as db2dsdriver.cfg) is catching its popularity among the customers due to its capability of allowing different DSNs and database properties configuration in a central repository manner. In addition, being in XML format, it takes a less of an effort for any user to get used to such configuration files. In DB2 Connect V10.1 Fixpack 2, CLI added new capability to db2dsdriver.cfg by allowing users to set special registers generically.
Before I go deep into the feature explanation, let me begin with answering few basic questions:
What are special registers?
A special register is a storage area that is defined for an application process by the database manager. It is used to store information that can be referenced in SQL statements.
To know more about special registers with examples, refer to the following link:
What is the existing method of setting special registers from client applications?
There are set of special registers which can be set (or updateable) by the client applications. Application can modify such special registers programmatically using “SET” SQL statements. There are few special registers for which DB2 CLI provides connection level keywords. Application can set these keywords either via db2dsdriver.cfg or db2cli.ini configuration files.
Limitations using existing method of setting special registers:
Setting special registers programmatically expects modification of the application source code and recompile each time special register needs added/removed/modified. Also, this needs to be taken care in all impacted application programs.
Using special registers which can be set as CLI keywords can be a better approach than former, but with limited list of such keywords, applications do not get complete solution. CLI can be enhanced to support requested special registers as a keywords, however with data server introducing new special registers at each release, this remains an ongoing solution. This expects users to upgrade their client drivers to be able to get newer special register support as keyword.
What is the newer mechanism CLI provides to address above situation?
To overcome the drawbacks of both the above approaches, it was desired to have a more generic solution to be developed. As a result, CLI has introduced a unique section of special registers viz. <specialregisters> in the configuration file db2dsdriver.cfg. This section allows users to specify a list of special registers that they like to configure. Based on the need, <specialregisters> section can be added at a DSN level or a database level or even globally.
During each connection to a given DSN or a database, CLI reads through db2dsdriver.cfg and processes <specialregisters> section in the following manner:
- read each special register name and its value from <specialregisters> section of a given DSN or a database
- “without scanning/interpreting” form a chain of special registers to be sent to the connected data server.
- upon the first SQL of the connection, flow chained special registers to the server
- server will process each special registers of the chain (along with the 1st SQL of the connection) and set it appropriately at the server.
As we can see from the above logical flow, with this feature, CLI has no dependency to know the special registers to validate. It will simply flow the entries from <specialregisters> section to the server and let server do necessary validations. Another benefit we can see here is because flow of the special registers is chained together along with 1st SQL statement of the connection, network trips to set the special registers is saved significantly now.
When server upgrade occurs and user application likes to set newly supported special registers, with this new feature of CLI, all user needs to do is to add that special register in their <specialregisters> section! As we can see, no driver upgrade is needed here in order o use newer special registers.
Illustrating usage of <specialregisters>
Having given some background, I can now proceed with the working of this feature. Let’s begin with adding <specialregisters> section to existing / new db2dsdriver.cfg configuration file:.
Sample db2dsdriver.cfg file
Interpreting <specialregisters> section from above sample:
1. Special Registers applicable across all DSNs/databases ( residing under global <parameters> section)
CURRENT DEFAULT TRANSFORM GROUP = 'MYSTRUCT2'
CURRENT LOCALE LC_MESSAGES = 'en_CA'"
2. Special Registers applicable for DSN = sample
CURRENT SCHEMA = 'MYSCHEMA'
CURRENT DEGREE = 'ANY'
CURRENT DEFAULT TRANSFORM GROUP = 'MYSTRUCT2'
CURRENT LOCALE LC_MESSAGES = 'en_CA'"
3. Special Registers applicable for database = sample2
CURRENT SCHEMA = 'MYSCHEMA1'
CURRENT DEGREE = 'ANY'
CURRENT DEFAULT TRANSFORM GROUP = 'MYSTRUCT2'
CURRENT LOCALE LC_MESSAGES = 'en_CA'"
The above configured special registers for relevant DSNs/databases come into effect with the first SQL statement given post connection. It is at this point the special register settings are applied at the server.
In the above application logic, "INSERT" is the first SQL statement post connection. Along with this SQL statement, the effective special registers list (as listed in the db2dsdriver.cfg) is formed and these special registers get set at the server. In case any special register setting at server has resulted in any warning or an error, those will be chained to the result of 1st SQL’s response. Application can call SQLGetDiagRec() API to retrieve any warning or error details to diagnose the problem.
Where I cannot use this new feature?
To enable client info properties, it’s not recommended to use <specialregisters> section. Existing mechanism either via CLI keywords or environment/connection level attributes can be used instead.
If application logic desires to set special registers during the connection (not at initial phase of the connection), or if they like to change the special registers in between, then setting special registers programmatically is the only way. New feature is useful only as initial value of the special register for the connection.
In summary, as an application user, one can get below benefits with the new feature:
1. Savings in time and network utilization by reduction in network flows
Reduction in network round trips between client and servers since most optimal DRDA protocol is used while flowing special registers set information to the server.
Moreover by chaining set of special registers along with 1st SQL of the connection saves another network round trip by using piggyback mechanism.
2. Less maintenance and upgrade of the driver:
The new approach avoids necessity of driver level upgrade just to exploit any new server special register. All users need to do is add the new special register entry in the <specialregisters> section to the existing drivers’s db2dsdriver.cfg file (minimal driver level requirement is V10.1 Fixpack 2). Knowing many big organization having thousands of client drivers installed at each workstation, this saving brings lot of relief to them.
3. Centralized maintenance:
Using central configuration method for db2dsdriver.cfg, users can now have much controlled manner to add/remove/edit the special registers for their applications. Also, with flexibility of using <specialregisters> under DSN, database or global level, user can tune their need quite easily.

Having worked for some time on LDAP for DB2,I thought it was better if I could highlight how and in which areas LDAP can help ,when working with DB2.So with a platform like that of developerette, I thought I would use this ,so here is a brief introduction on what is LDAP and how it best fits while working with DB2.
What is LDAP?
Today people and businesses rely on networked computer systems heavily to support distributed applications where the key information is stored in central repository.
Useability scenarios for LDAP fitting best for DB2
The figure represents a typical LDAP topology where client connects to "payroll" database using the cataloged information present in the LDAP server.
Supported LDAP servers for DB2
IBM Tivoli Directory server
Microsoft Active Directory server
Sun One LDAP server
Netscape directory server
This was an attempt to highlight the major applicability scenarios where businesses can make best use of LDAP in order to better manage their data in a distributed environment.I would be probably covering the basic configuration and some CLP LDAP commands and their usage in the next part for a better hands on experience.
Recently, there has been a lot of buzz around WEB APIs and developer versions of popular social networking companies like Twitter and Facebook. There was a time when the industry was obsessed with SOA and you had to be doing SOA to do it right. Reusability and Loose coupling were the much needed aspects. While this is still the case, the use of Web Services to implement the service-oriented architecture is giving way to REST-based services which are much faster – to implement as well as to understand.
Also more and more individuals are interested in creating their own mobile apps with the advent of platforms like Android SDK, IBM Worklight, Phone Gap and trigger.io
REST is Representational State Transfer. It’s a protocol based on HTTP which defines everything on the internet with a unique identifier (state).
So for example your Facebook profile picture is also a resource on the internet which is uniquely identified. You can GET it using a URL, you can POST a new picture of yourself, PUT (edit) the existing picture or DELETE the picture.
The catch is that you are not doing all this using the Facebook page, but using URLs (or more specifically – Facebook Graph API); the advantage – you can plug this functionality in a custom app you write.
So how does this all fit in together? Let’s put together the pieces of this jigsaw puzzle and look at the primary actors/stake holders in this space.
The Provider Story
The providers are the companies (or individuals) who have built some custom functionality which is unique to them. They now want to make it open for anyone to use. So they come up with their APIs (Application programming Interfaces) which are on the WEB, hence called WEB APIs. Simple, isn’t it?
Take a look at some of these to get better idea.
Twitter Web API - https://dev.twitter.com/docs/api/1.1
The Consumer Story
The simplest to understand, consumers are simply put the people who use the WEB APIs. So this is you and me. The consumers can also be enterprises. We need the APIs. How else would we know how to get that much desired resource which is lying in some corner of the Internet?
As already discussed you and I can plug-in the functionality provided by someone else in our own app – something like a mashup.
A very common example is companies using Facebook/Gmail credentials to let you log in to their websites and then posting content on your timeline. You can use Facebook Graph API for this purpose.
The primary tenet is reusability- why build something which someone has already built and is making publically available.
WEB APIs or REST based services open the gateway for cross-company collaboration.
This post might help in integrating Facebook login into your website.
The Middle Managers
You need a cab in a city which is new to you, what do you do? Yellow Pages...
The Middle Managers are the yellow pages (intermediaries) which collect information about multiple providers and make them available to the consumers.
Not all companies have a wide social appeal, most are more specific and domain-oriented. The central managers come to build the bridge between producers and consumers which would otherwise not know each other at all.
In addition to acting like a directory of provider WEB APIs, middle managers may choose to provide certain value-adds to the providers – like providing API Analytics, which help the provider improve their services, or help know who is their primary customer base, when was the API accessed the most, which geography this is most popular. This is indeed an upcoming trend. This is where IBM Cast Iron Live for Web APIs comes into picture.
Other examples include the likes of Apigee and Mashery.
WEB API is an emerging and hot trend, but it is quite simple to understand, isn’t it?
I would be happy to receive any questions/comments on this topic.

Module 3 : Enterprise Architecture and The Cloud
With the advent of the cloud, there was an immediate worry about What happens to the existing Enterprise software and hardware? What happens to my existing apps? Do I need to re-architect everything for the cloud.
The truth is that most enterprises are taking only baby steps towards Cloud Computing. e.g. Email, Salesforce, Web apps/sites, Office apps etc. The main reason for this is the initial skepticism about a new buzzword as well as lack of enterprise-readiness to adopt the Cloud Strategy head on. The main reason for the slow acceptance is mainly that enterprises are just not aware of their business challenge they want to tacke with the Cloud. The most appropriate step is to first understand you problem and seek the question to which the answer is Cloud.
On the other hand, enterprises have already worked on modernization and rationalization of most of their legacy apps. Also they have already implemented a reusable modular architecture in their enterprise by the use of SOA (Service Oriented Architecture) principles. SOA Governance whose need is now being understood by many enterprises is an added winning advantage for their enterprise. Because we already have it, the SOA governance framework can be extended to govern cloud services.
So is Cloud the end of enterprise software? Do enterprises really not need to buy hardware any more?
The answer to this question is largely dependent of the business problem of the enterprise. If its a large telecom company or a bank , doing away with entire enterprise software or hardware makes little sense.
However, for college graduates who are looking at establishing their own startups, the need for spending a lot of money on the hardware is virtually eliminated. They can rent a PaaS solution (the most common is Amazon EC2 <Elastic Compute Cloud> instances) and get to work. In cases like startups or pilot projects, Cloud Solutions are actually a boon.
What are the big companies doing about cloud? Oracle, IBM and Microsoft?
Disclaimer: The following thoughts are my own analysis and most of it is from content of Jason Bloomberg's conference. They do not reflect the views or opinions of my company whatsover.
Oracle has launched a suite of products around IaaS, PaaS and SaaS. Oracle offers Sun hardware for their IaaS solutions and are essentially hosting Oracle middleware on the cloud. They call their SaaS solutions as Oracle Fusion Apps.
IBM's cloud strategy is not aimed at the end-consumers. Their target is the big enterprises and large telecom providers who actually provide enterprises with the infrastructure to host their cloud solutions. So these are more like the ISPs (Internet Service Providers). IBM's solutions are mainly around PaaS.
Microsoft basically brand their cloud solutions under the Windows Azure tagname. Windows Azure Platform and Windows Azure Platform Appliance is their PaaS offering whereas their major SaaS offering are the Office 360 apps.
So how do I get out of this mess? To use or not to use the Cloud?
The answer to this and the enormous Cloud solutions is two words - Architecture and Governance.
It is essential to identify the business problems the Cloud best addresses, and to see where the Cloud fits into the overall IT strategy of the enterprise. What are the pros and cons of Cloud versus any other alternatives, and how the Cloud fits in the overall governance framework.
The important thing to remember is not to grab any solution just because your favourite vendor has launched it, but you analyse objectively if your enterprise really fits into that readmade suit.
What can be a sample Cloud Computing roadmap?
Disclaimer: Directly from the docs
A simple Cloud Computing Roadmap can be enumerated as follows:
What can be a phased strategy for migrating to the cloud?
This article elaborates the six main phases for Cloud Migration for Amazon Web Services (AWS)
Phase 1. Cloud Assesment Phase
Phase 2: Proof of Concept Phase
Phase 3: Data Migration Phase
Phase 4: Application Migration Phase
Phase 5: Leverage the Cloud Phase
Phase 6: Optimization Phase
I am a product developer? Do I have to redesign by products for the cloud?
The essential thing to understand is that unless the applications are re-architected to take advantage of Cloud benefits like Elasticity and Fault Tolerance, there is little sense in using a Cloud Solution at all. As the phased strategy to Cloud migration suggests, it is very important to take incremental steps to architect your solutions for the Cloud.
When you design with the aim of leveraging Elasticity and Fault Tolerance benefits of the cloud, you will end up with a better architected app. You don't know aheas of time how many Cloud instances your app will be running on, as such is makes perfect sense to spend a little time initially and design your app FOR the Cloud.
Can I ensure my ACID transactions in the Cloud?
We have grown up reading about databases and the magic word - ACID - Atomic Consistent Isolated Durable and as such we believe that all database transaction should necessarily be ACID for several reasons. However, with the advent of transactions in Cloud, it is no longer possible to have immediate consistency of data at all instances. What Cloud assures is Eventual Consistency - i.e. - Data will be consistent after a set amount of time passes since an update.
ACID is gradually giving way to BASE in the Cloud Context.
Basic Availability - Cloud supports parial failures without leading to a total system failure . (Cloud environments are inherently partition tolerant)
Soft State - Any change in state must be maintained through periodic refreshment.
Eventual Consistency - Its okay to stale some data some of the time
The BASE requirement for transactions in Cloud also suggests that companies where real time data and accuracy is of prime importance, Cloud might not be such a good solution. A clear example of where Cloud cannot be a good medicine for all ills. Examples may include, real time inventory management for product availability and banks.
(Banks may not want to adopt cloud for reasons other than BASE - security and government regulations may be major challenges).
The main takeaway for this module would be that the adoption of cloud depends on what is your unique problem. For Cloud, one size does not fit all. An enterprise needs to carefully weight its app's requirement for scalabilty and elasticity and then decide which Cloud deployment option is right for them.

Meet Ms Madhuri Rao, the enthusiastic and versatile assistant professor at Institute of Technical Education & Research, Bhubneswar.
Prof. Madhuri has a unique way of telling her stories, making them interesting and inspiring at the same time. She is a proud professional, daughter, book lover and a guide to her students. She's always ready to try something new and find motivation in the simplest of sources. Her career as a professor is a conscience choice to nurture and interact with young talented minds. Needless to say, her connection with her students is invincible!
Thank you Ma'am, for taking the time to share a part of your life with developerette. We hope to read more from you in the coming days.
Read about Prof Madhuri's unique style and her advice to follow your heart and keep a clear conscience while choosing your different roles as career women, wives and daughters.
1. Please share some details about your professional background, family and interests
I am from a family of five daughters. I being the 2nd eldest ,always had a very responsible role to play . However I also play football during my school days. I always enjoyed shouldering responsibilities , be it in school , home or in the football field.
With all five of us going to the same school and seeing the same teachers and knowing the same rules , made our growing up an experience unique in every way.
Dad and Mom could not have given us a brighter childhood and upbringing than in the way they have nurtured us.
We also made a record at Scared Heart Convent School, Jamshedpur , as the 2nd and the last family to have 5 daughters schooled in the same place and for us as a family with an association of over 2 decades.
Well, details of each of my family member may be shared only in a special request in order to not bore away the other majority of readers!! :)
Reading is my passion. Now a days programs on History Channel, Animal Planet and Discovery Channel also fascinate me....
After having finished Engineering at B.I.E.T , Odisha , I pursued my Masters in technology from Bharath University , Chennai .
Economics is a subject that always fascinated me , and I therefore studied a second postgraduate course on M.A(Economics) from University of Madras in Distance mode.
I am now pursuing Ph.D from Biju Pattnaik University of Technology , here at Bhubaneswar .
I started my career at Slash Support as an Application Engineer in the year 2005 and then moved on with higher education.
2. What made you choose a career in IT education? Can you explain how you guided your career to be where you are today?
I always wanted to teach. I have been doing it since childhood. Helping my younger sisters with their studies was something I always enjoyed. Being close to books always made me happy and reading and exploring new things gives me tremendous pleasure. I wanted a career where I could read something new all the time and I slowly managed to walk into imparting IT education. Most of my friends and classmates are big shots in IT companies, etc... but I never desired it that way. I want to see myself as a Ph.D and I do desire to work further towards a PDF as well. I am quite an orator and find delivering lectures and interacting with youthful minds and souls very satisfactory.
3. How did you guide your career to be where you are today?
By listening to my heart and conscience, and being sound and awake with realization of what choices I am making in life!
4. How have you balanced your professional and personal demands simultaneously?
Well,my upbringing is as such that I was always taught to give a patient listening to my very conscience and that little things always fails to demarcate between things. It sees no boundaries. I guess its all about doing right and wrong things. Its not about Personal and Professional things. As a teacher you can never say that you have Professional hours. You go home and you prepare for you next lecture. You cannot be annoyed even if you want when a concerned parent reaches you at hours other than 10 to 5. I stay balanced by being happy and I do things that make me happy. My parents guide me through my strenuous hours. Staying only 500 Km away from them also gives me an opportunity to meet them as often as I desire. I also have a wonderful group of friends and especially Vinod Sir & Laxmishree mam,who share their moments of research , lecture , family stuff with me and so do I. My HOD , Dr Pattnaik , and Associate Dean Dr Alok are very motivating people who themselves practice punctuality , righteousness and simplicity . Our School of Computer Science celebrates all festivals, organizes picnics and other cultural events as well. I must say that I am blessed with a competitive yet caring and enthusiastic work environment. Well on another note, I also try other things like swimming & yoga.
5. What are some of the challenges you face in your role and how do you deal with stressful days?
The major challenge that I see is the acceptance of responsibility of one as a Teacher . There are some moral guidelines and that differs from teacher to teacher. You cannot have those moral values engraved literally. Teaching to undergraduate students who would soon be a tax payer in the society , means a lot. We have the responsibility of making an upright citizen, but how far we succeed cannot be measured always. We measure the success of the Institute by the number of placements it seeks. Well, Teaching cannot be standardized. Newer technology , new methods , new concepts and a generation already ahead of us is what we have to face. Sometimes I also have to watch Cricket matches which I dislike, just to be well informed to face these kids.
Moments of stress come in everyone's life . When I am forced to do what I don't like, I find myself irritated and stressed. I sometimes reason it out,and mostly I share it with my Dad and Mom , depending on the kind of concern I have. Sometimes I share it with my sisters,and well when I realize that nobody could help... I leave it to GOD.
6. The girls in your college are aspiring women in technology. What is your advice to students to stay focused?
The Life's a stage that these young ladies are about to step onto ,its about making decisions and choices. Choices and decisions that stay for the rest of your life. While making these decisions you should realize of what is involved. Can you make a living out of this choice for the next 20 years. A career of 20 years is what you should be looking at. As women,we have responsibilities towards parents ,sisters , in-laws and that very special person. While at the same time we also have another world of professional entities. There is no common mantra or strategy of being able to excel in both of these dimensions. Each one of us have a different story to narrate and each one of us is great in our own way.
I believe in what Shakespeare said - " Some people are born great. Some work hard to achieve greatness while others have greatness thrust upon them ".
My advice to you young ladies is to follow your heart and make the right choices. You have a story to talk about in future.

In this instalment, I will cover in detail about the Cloud Deployment Options available and also speak about the multitenancy models in the cloud.
Module 2 : Cloud Deployment Options
Infrastructure, Platform and Software are NOT the only things which can be delivered as a service. So this list is not exhaustive and probably you can get anything what you want as a service. Or so to say, you can get whatever the cloud provider provides you as a service.IaaS, PaaS and SaaS basically provide a separation of responsibilities in terms of what resources are managed by the providers and which of those are managed by the consumers.
On one extreme there are on-premise applications in which there is no cloud provider responsibility at all, whereas the other extreme is software-as-a-service where everything down from the hardware basics like networking, storage, servers and visualization to the applicatkions and data is managed by the cloud provider. IaaS and PaaS fall in between these two extremes.
With cloud computing comes the concept of mutitenancy. Tenants are users or applications which share the same resources and yet their data remains separate. This ensures security because even when the tenants use the same resources, their confidential data remains visible only to them.
There are several Mutitenancy models which have become popular with the emergence of Cloud Computing. The maturity varies from simply providing a virtualization layer over existing software to writing programs/software architected from scratch designed with cloud(scalability/elasticity) in mind.
Shared OS - In this model both the underlying hardware and OS are the same.
Shared Database - In this model the tenants share the same database. The applications architected for such a model should be carefully designed to avoid different tenants having the same table name.
Shared Table - This is the most mature model for tenancy. Requires careful planning and application has to be architected from scratch with concerns of elasticity and data separation in mind. In this model the underlying tables in the DB are also same, the data is carefully separated per tenant. We can say that this model supports full mutitenancy, it has more complex design but the most Effective Resource Usage and Scaling.
What are some of the services available to Cloud Consumers in IaaS, SaaS and PaaS ?
In this module, I have touched briefly upon the various Cloud deployment options. However there is a lot of information available on these topics. I hope this overview helps you to dig deeper into the area of your choice and also provides a high level picture for you to fit in the pieces of the Cloud Puzzle.

Meet Sugandha, the lively and compassionate Program Director at Websphere, IBM.
Sugandha is a free spirit who takes life in her stride and plugs away at situations, good or bad, one at a time. Her successful career, her devotion to her family, her initiatives towards the development of women at IBM and colleges across the country are all components of the contributive and fulfilling life she leads.
She is an inspiration and role model to many as she leads her team and her family life seamlessly.
In her interview with developerette, Sugandha talks about setting priorities, building on one's strenghts and support system and balancing that perfect balance we all strive to achieve!
Thank you Sugandha for your time and sharing your philosophy! We look forward to many more interactions with you on the developerette forum.
Please tell us about your current role and responsibilities, your family and personal interests.
I lead development and support for Connectors in WebSphere and focus on client growth for Connectivity & Integration and Messaging in ISA . My responsibilities include defining the product(Connectors) roadmap with architect and Product Line management, delivering it to market on time and ensuring customers are happy using it. Responsibilities also extend to interactions and interlocks with sales, tech-sales for supporting product growth in market. I am also responsible to work with my team on their career path and development. In addition, I engage in IBM's wonderful give back model of serving the community by delivering technical talks at colleges or grooming students in colleges through group mentoring.
I have a small family. My husband is also in the software industry and I have a 3 year old daughter Meera who keeps me pleasantly occupied.
Whenever I’m free, I like to read or cook something fancy. I love to travel and that it makes a more “aware” person.
What is your way of dealing with stress? How do you integrate work and personal/family life?
I believe am able to sense the onset of stress. When I see there’s a situation which can turn stressful, I sit back and think about the reasons: Is it because of too little time? Too many variables? Because of people? Or something personal? Once I figure that out, I try to prioritize and start plugging away at the problem at hand.
A good way of dealing with stress is talking. I usually call up a friend for advice, take a deep breath or just read to my daughter to take time off and start afresh.
A secret and quick way to overcome stress is by keeping an optimistic view! Positive attitude keeps me going.
Both family and work are important. At any given time, one of the two will require more time and attention. You need to smartly address what needs to be addressed first and modify your approach. My evenings are dedicated to Meera post which I align a couple of hours to work. Having a schedule really helps me stay on track.
When I’m on a holiday, I ensure there is no interruption in my family time unless there is an emergency at work. For this seamless integration, help and support from colleagues and family is critical.
A lot of girls are faced with a choice between family and career. What is your advice to them?
There isn’t a choice between Family and career. They go hand in hand and simply choosing one isn’t fulfilling. They are each other's motivation factors. Priorities can be switched but my advice is never to make a choice and compromise.
Family, friends and career should all move along together.
Please tell us about the diversity network that you have led and how it has helped women at IBM.
A bunch of women across ISL at IBM got together to discuss what would aid their development. Surprisingly, everyone spoke about professional development. In the past, women were focused on “How can I manage my family despite my job” And now, we have moved on to “How can I grow professionally despite my family demands”
That was the inspiration behind the charter for the last two year for ISL diversity group ‘Shakti’. It was recognized in Winspiration 2011 as an agent for Gender Diversity Change
There are various aspects to Shakti (much like developerette) where we a) provide mentoring, b) focus on products, codes and sales c) focus on business communication conducted by leaders and d) provide selective job shadowing
The charter is designed to provide holistic learning for the participating women.
What are some interesting career options in IT for women?
IT is a vast field with various career options. From the conventional roles in programming, testing and developing to the unconventional roles in sales, tech sales, and strategy, there is a lot of versatility.
The decision must be based on your aptitude and not the general trend. A product management role with people responsibility, hardcore development or technical evangelism are all equally fulfilling and challenging. Also remember that Management won’t take you away from technical arena and technical development won’t take you away from people centric roles. In a nutshell, , there is no shortcut to promotions or success. Believing and enjoying what you do, challenging yourself out of your comfort zone will take you on a fulfilling career journey.
The choice is based on your interest and there are literally scores of choices!
I am Tulika Garg and I joined IBM India Software Labs in Jan 2011. I completed my Bachelors of Computers Sc. & Engg in 2009 . It was during my schooldays when the "IT" bug caught me and I was determined to become a software engineer. I have worked with a telecommunications based company for an year ,before joining IBM. When I joined IBM, with just an year's experience I realized there was so much more to learn. Its altogether a different feeling of working in a firm like that of IBM,and when you are referred to as an “IBMer”. I am a part of The Information Management group and I closely work with DB2-CLP and DB2-LDAP components .I am a part of the L3 continuing engineering(CE) and new development team(ND).I have presented a poster in the internal conferences like WIT(Women in Technology) that was conducted by IBM last year. I don't have any list of achievements as such in my name,but then I marvel each working day of mine with a sense of devotion,commitment,and my effort.
When we are fresh out of college,we have a mixed bag of feelings. We have zeal to do whatever task is assigned to us,we have new hopes but yes along with that , some apprehension does exist. Performing in the corporate world,competition ,work pressures and various other things start creating a tornado of professional chaos in our minds. I think it is important to just maintain the momentum with which we start and learn from our experiences which we gain with time.After all women possess the innate qualities of patience and perseverance ,and we being the 'women in technology' just need to make use of it.
My work here is related to supporting the customers that use our products,along with improving and enhancing the efficiency of our existing components. Resolving the customer issues,providing them solutions in a timely manner ,fixing defects ,enhancing the code to meet the new requirements comes as a part of my job. Sometimes people don't see support jobs in a very good light but nevertheless they are very crucial and important. Ultimately it is the customer experience of a product that speaks for a company. And I trust my acumen and feel good at the end of the day having done my job and feel pride in it.
The job I do is action-packed. Its never monotonous. If there is anything typical about a working day here, it is nothing short of exciting,rewarding and at times even challenging when we have to meet the deadlines.
Achieving a work/life balance is equally important and it is so good to read how my fellow bloggers , the 'women in technology',take out time from their strenuous routine and pursue their passions. They are definitely a source of inspiration for all the budding engineers as well as those who are still struggling to achieve this balance. With all my work underway,my distress routine includes spending time with my family and friends,taking out time for myself and indulging in my hobby activities like dancing and cooking. Just trying to remain calm and composed ,not getting bewildered with the veritable storm of work related questions going on in our minds is the key I guess. The answers to these can be found only with a peaceful state of mind,which can be achieved by maintain a proper balance. So don't get swayed with the hurling wind but stand strong and just be yourself!!!
This women's day i.e. 8th of March 2012, I had the opportunity of attending "Enterprise Cloud Conference" by Jason Bloomberg. Jason Bloomberg is a SOA and Cloud thought leader and the president of Zap Think. The conference was aimed at cutting the crap around cloud computing. Cloud has become a much used jargon without many people understanding what it actually means. So as a representative of you all, I would like to share a few takeaways from the conference.
The conference was aimed at providing a bird's eye view of cloud computing terminology, what it is and what it is not. I would follow the same pattern used during the training to report my learning. The theory was complemented by a few practical case studies of companies who have used the Cloud to run successful businesses.
The conference was held in 4 cities, Bangalore being one of them and saw several companies participating. There were delegates from IBM, HP, Cisco, Akamail, 3i Infotech, Mphasis, Mindtree, Samsung and Fidelity to name a few.
Module 1 : Cloud Introduction and Definitions
So what is this whole Cloud thing? What are cloud characterisitics?
Cloud Computing is first of all not a computing model. It is essentially a delivery model. It has been existing for decades now, so to say this whole cloud computing thing is Old Wine in New Bottles. What essentially this means is that Cloud Computing is another term for services delivered over the Internet or the World Wide Web. This has been long existent in SaaS applications (Software as a Service). The email and web apps which you have been using for quite some time now are variants of this. Where Cloud goes ahead is delivering an OS or even an entire hardware configuration as a service. This means that small startups can enjoy the advantage of huge computing powers and custom platforms without actually having to buy hardware and set up their own datacentre.
For the more technical definition-savvy, here is the Cloud Computing definition from NIST (National Institute of Science and Technology)
"Cloud Computing is a model
for enabling convenient, on-demand network access
to a shared pool of confugurabke computing resources (e.g. networks, storage, applications and Services
that can be rapidly provisioned and released with minimal management effort or service provider interaction"
What are the Deployment Models for the Cloud?
Deployment model refers to how you want to use the cloud to your organization's advantage more so where does the data resides and who operates the Cloud.The various Cloud Deployment Models are
In Cloud Computing anything which can be delivered to end-users on the Internet becomes a Service Model. The most commonly referred to Service models are SaaS, PaaS, IaaS
So when we say cloud, who are the actors involved?
A Cloud like any other service has a provider and a consumer. These are the primary actors.A Cloud Consumer is a person or organization which uses services from a Cloud Provider whereas a Cloud Provider is a person, organization or entity responsible for making a service available to the interested parties.
Besides these there may be Cloud Auditor which maintains the regulatory compliance to government guidelines; a Cloud Broker which helps a consumer to select and route to an appropriate provider much like an ESB(Enterprise Service Bus).
The backbone of all these is a Cloud Carrier which refers to the ISPs which provide Internet connectivity. No matter how fast your Cloud might be, if your network is slow, everything is slow in effect.
Actually No. SOA and Cloud are two different things. Although both are related to services. But SOA is an architectural approach which guides how you should design your enterprise applications as a set of loosely-coupled reusable services; whereas Cloud is a deployment and operational model. Cloud can be host services which have been developed as per SOA philosophy.Does Cloud provide me infinite resources?
Because of the vast computing and physical resources on the side of the cloud provider, the cloud gives an "illusion of infinite capacity". So as a matter of fact Cloud does not literally provide infinite resources. The Cloud characterisitic which gives this illusion is elasticity.
I am really happy for my friends. Their hard work was won and recognized.
IBM CoE Community Academia for Ambassador Association listed students that play a vital support role since the day of launch of program.
I am proud of my friends Pooja, Karthik, Virendra, Dharma Teja . Have a great life with exceptionally fantastic work.
All the best and congrats to all other splendid students.
