Sandy Carter: Service Oriented Architecture (SOA) -- Off the Record
SOASOA 060000JRQN Tags:  service_registry business_process_mgmt service_component_arch composite_apps 1,283 Views
A lot of discussions have occured around semantics for SOA. Any thoughts on these definitions for SOA "terms"..
Service – a repeatable business task represented by a software module deployed on network accessible platforms provided by the service provider. Its interface is described by a service description. It exists to be invoked by or to interact with a service requestor. It may also function as a requestor.
Service Orientation – an approach to integrate business tasks as loosely coupled, linked services
Service Oriented Architecture –An architectural style of the structure of a software system in terms of its components and the services they provide, without regard for the underlying implementation of these components, services and connections between components
Composite application - a set of related & integrated services that support a business process built on an SOA
Components - Definition of a modular unit of functionality, accessed through one or more interfaces. A component may be composed of other components, but a component is not necessarily a service.
Service Component Architecture (SCA) - a set of specifications which describe a model for building applications and systems using a Service-Oriented Architecture. SCA extends and complements prior approaches to implementing services, and SCA builds on open standards such as Web services.
Business Process Management - Covers the full range of application-to-application, inter-application, workflow and person-to-person process management, including process design, automation, management, and continuous improvement.
Service Registry - a searchable registry of service descriptions where service providers may publish their service descriptions. Service requestors may find services and obtain binding information (in the service descriptions) for services during development for static binding or during execution for dynamic binding.[Read More]
I am here in a great hotel in London ...! Today we had the SOA Business Centric Summit in London at another cool place... with over 400 customers!
The SOA summit was a great way to hear from the London customers doing SOA, like City University, Standard Life (Ian writes that "Our measured re-use benefit now stands at 8.5 miillion sterling (16 million US) Feel free to quote us. Well over 100 applications from large to small deployed to our SOA now and many more planned", Norwich Union, and Travelex!
Check out John Patrick's Blog on the SOA AR day as well!
I just attended the Gartner BPM conference in San Diego. There were over 1000 attendees -- growing considerably from last year's conference. It was a very interesting conference -- starting with Simon Hayward's Keynote walking through critical success factors for BPM. This was the talk of town -- there was a lot of discussion on the keys to success for BPM enabled by SOA.
I had lots of discussion on "What BPM is?" -- a discipline that involves thoughtful focus on process -- selecting the right process to focus on, looking at the organization, the culture, and the way you manage process improvement and innovation. Also I had lots of great discussions on the required Software Capbilitty and the value of SOA (Which to me is when you see the real value of BPM -- with SOA flexibility !)
IBM is investing heavily in BPM, and have seen numerous clients from small to enterprise across every industry see its value in growing their competitive advantage. We introduced 5 starting points -- flexible starting points -- to assist customers to deploy BPM with SOA at the rate and pace they need for real business results. The 5 starting points are Modeling and Simulation, Monitoring, Rules and Frameworks, Content centric processing, and process choregraphy. We have also expanded our BPM with SOA capability and expertise showing off the WebSphere Business Services Fabric, the BPM methodology, the SOA business catalog, the Filenet BPM capabilities, and new process models based on opens standards like PCF.
I also saw some great customers talking about their lessons learned. Speaking with me on stage was ANZ -- Barry McGibb - and he did a great job outlining his vision and approach for BPM with SOA. Another favorite of mine was the customer speaker - Tom -- from Sloan!
The biggest debates that I heard at the conference were:1) How to align business and IT and get them as excited about BPM as IT is. In fact, about 40% of the attendees at this conference were from the business side.
2) The second was the relationship of BPM and SOA -- in fact Darryl Plummer did a great talk on how BPM and SOA are joined at the hip. Here are my thoughts on the subject that we recently had published!!
The role of Business Process Management in a Service Oriented Architecture StrategySandy Carter, Vice President, SOA and WebSphere Strategy, Channels and Marketing, IBM
In today's competitive environment where companies are merging, consolidating and striving to uncover new growth opportunities, savvy business leaders are recognizing the value that comes from working more closely with information technology (IT) professionals.
Driven in large part by the growing adoption rates of a service oriented architecture (SOA) strategy, more and more organizations are realizing that the alignment of IT and business delivers tangible results and significant returns in terms of productivity, competitive advantage and cost savings.
However, to seize these new opportunities and realize the benefits that can be derived from an SOA, companies need to streamline their business processes and eliminate the recreation of the wheel that too often happens when an organization and its technology resources are locked into silos.
For example, these business processes can include such functions as ordering supplies, reimbursing expenses or booking business travel. When each department or team within a larger organization has its own ‘system’ to handle these types of business processes, it may prove effective for a smaller subset of the company but is largely ineffective for the entire business. Consider the advantages that can be reaped in terms of productivity and cost savings when there is an agreed upon approach to filing an expense report or automating travel requests.
Addressing these issues and uncovering ways to automate and improve business processes without requiring additional resources is top of mind for today’s organizations as they aim to more effectively and efficiently compete in an ever changing marketplace. This growing need has led to the rise of the business process management (BPM) market.
The Growing Demand for BPMBPM is a discipline combining software capabilities and business expertise to accelerate process improvement and facilitate business innovation. One could argue that BPM is based on the principles of SOA with both aiming to empower the organization to more quickly respond to changing market conditions that result from planned events such as mergers and acquisitions or external influences such as competitor moves.
There are several factors driving the increased focus on BPM. These include the need to:
Ensure consistency throughout the company, especially with regard to compliance;Optimize processes for maximum efficiency;Automate manual processes to reduce time consuming administrative tasks;Integrate complex, redundant processes to avoid the constant recreation of the wheel;Mitigate risks through a single, unified view of the organization.
A successful BPM solution will take existing processes, streamline them to meet business goals and ultimately impact the bottom and top lines in a positive way. The value of BPM is further evidenced by the results that can be realized from business and IT working more closely together. One of the most significant benefits is the fact that BPM helps to put business process control in the hands of business managers. By providing decision makers with up-to-date business information, BPM allows them to make better decisions immediately without relying on IT support.
The Role of Business Process Management in an SOABPM is growing in popularity and is complementary to SOA due to its ability to help make business processes more efficient and effective while enabling an organization to more easily adapt to changing business requirements.
BPM based on SOA is technology’s response to the growing demand for a flexible business environment that is not hindered by application silos.
When business processes are automated and streamlined and supported by a strong SOA governance framework, BPM can deliver on its promise of transforming IT processes to dynamically adapt to business needs. For these reasons, BPM is being widely embraced. In fact, analysts at IDC state that the BPM tools market will reach $3 billion by 2009.
The powerful combination of BPM to streamline business processes within an SOA strategy will help position companies to become industry leaders while ensuring they are poised for continued success.
For this to happen, however, business processes must become independent of specific information resources and specific task automation applications. Specifically, the integration technology must loosely couple the applications and resources that make up the process, otherwise the logic of a process will get hard-coded into a particular technology platform, which may be expensive to change and therefore defeat the entire purpose of BPM.
Business Process Modeling: The ‘Other’ BPMThe need to model business processes before they are deployed in an SOA is becoming increasingly more important, especially as the demand for BPM continues to rise. First, however, let’s understand that BPM is both a management discipline and a technology platform and that modeling is a complementary and critical aspect within a larger BPM strategy.
As a management discipline, BPM replaces traditional views of business based on discrete functional organizations, systems, and metrics with those based on cross-functional core processes aligned with high-level business objectives. As a technology platform, BPM provides the set of software tools needed to optimize performance, make abstract performance goals concrete, connect them to process data, automate and monitor process activities, and provide a platform for agile performance improvement.

IBM is the SOA Market Leader and Vendor of choice for SOA Deployments! (Based on results from Springboard Research conducted in Asia Pacific)
A recently published report from Springboard Research. IBM and other SOA vendors were interviewed. Assessments were made on 261 CIOs and IT decision-makers' level of awareness, familiarity and a range of issues related to SOA deployment. Countries involved in the study were Australia, China, India and Singapore. Springboard has been kept up to date re our SOA solutions and strategy through various briefing sessions and through the recently concluded Analyst Insights event in New Delhi, India.
IBM is a clear leader in the Asia Pacific SOA market; among the 113 SOA users interviewed in the region, 47% said they have deployed a solution from IBM while 41% of these said they consider IBM as the market leader. IBM is a favourite with respondents planning to deploy SOA also as 49% of the 128 respondents interviewed by Springboard Research considered it best suited to help them migrate to SOA..."

Well, I am very excited as we just went live with Project Zero, an incubation initiative focused on helping to simplify the development of next generation web applications. This project is unique in that it is being developed openly on the public website -- utilizing feedback from the internet community -- under the technical leadership of Jerry Cuomo and Jason McGee. (Great techies if you haven't met them -- they have blogs too!!)
The website will offer a radically simplified scripting runtime with application programming interfaces. The site also features forums to encourage developers to give feedback and join a community interested in taking advantage of this new technology.
Since this is a view of how SOA and Web 2.0 work together, I'd love you guys to check it out! Let me know what you think!
It’s free – visit Project Zero

OK Gang! One of our big announcements this 2H SOA Launch is Process Integrity. End to end process integration is required to hold your services, information and users together. This integration must be robust and scalable – otherwise it will restrict you from growing your SOA and building on your initial successes. As you move from basic to advanced SOA, you should be able to use the same products and architectures in an expanded and more advanced way.
So the architecture must start with the ability to provide Process Integrity, even if you don’t use all the capabilities in every project. Robust capabilities must be part of the middleware layer. For example, let’s look at the Enterprise Service Bus. There are several types of ESBs, depending on what they are being used for. An in fact, it’s very possible that you might have different ESBs running in different domains. But whatever ESBs you are running, they must be able to grow with you and provide scalable connectivity as your SOA becomes more advanced. This also means that you might federate multiple ESBs, so that various ESBs are integrated into a larger architecture.
Security and quality of service are key to a successful SOA environment. Even if you don’t need the full set of capabilities in your first couple of projects, you need to ensure that your SOA environment is capable of growing with you. As SOA matures, it will very likely be the basis of a large percentage of IT projects in the future. It’s hard to think of large IT projects that don’t focus on security, scalability, availability and performance. Don’t think of your initial project as something that will be thrown away in the future. Think of them as laying the groundwork for your long-term architecture.

I am sitting here at the US Open at what ESPN calls the best day of tennis at the US Open yet! We are hosting a set of customers here at the IBM suite (yes,this is the way to see tennis!) I got to see 2 unseeded men's double teams, Martina Navratilova with her double partner Petrova and tonight is Federer and Blake. It was a great day, great sun, and perfect games. Funny, I went shopping for my mother in law and saw Lauren and Lacoste and other name brands selling cool US Open logoed wear. Interesting how things have changed!
Now why I am here besides the tennis and weather? Well, of course, SOA is behind the US Open!! How?
Well, IBM has been the US Tennis Association’s official IT partner since 1990 because it can do things like support the 27 million visits that came from all around the world to the US Open’s web site for live scores in 2005.
Thumbnail sketch of how score updates happen: Umpires officiating each of the US Open matches hold a device in their hands that they use to keep score. All these devices feed into a database which holds all the scores from all the matches. From there, the constantly changing score information is fed to servers that can be accessed by people like you and me through the US Open web site.When score updates are sent to the Web servers, they begin their journey in a format that is incompatible for use by the Web servers. IBM uses WebSphere software to transform messages in-flight between one protocol and another so that when the message arrives, it’s usable.
All this takes place without ever altering or touching the source information. This WebSphere software has the ability to transform the messages into dozens of different formats simultaneously so that the same information can be used by many different kinds of consumers at the same time. Score information is less than 7 seconds old by the time it reaches computer screens and it reaches tens of thousands of users simultaneously.
US Open achieves outstanding flexibility by accomplishing the repeatable business tasks that make up its scoreboard processes with modular, interchangeable software services. This is a hallmark of SOA.When a match begins or ends, when a game is won, or when a point is scored, these are examples of “events”. SOA from IBM gives US Open the ability to sense and detect events such as these and trigger an appropriate reaction or response with is based on business rules.
Without the flexibility that comes from SOA, US Open would have had to custom-code the system and then suffer the cost, risk, and expense of re-coding it every time they wanted to make a change. The US Open Web site’s volume of traffic spikes to 50 times its annual average during the tournament and then falls back to a trickle during the off season. The infrastructure to support this massive jolt relies on a concept called “virtualization” which allows US Open to handle huge loads without having to over-invest in a bloated infrastructure that sits idle in the middle of winter.
