Jason McGee will be leading the second GWC Lab Chat this week on Wednesday, 4/20. The very timely topic is related to recent announcements from IBM regarding the IBM Workload Deployer (see previous posts). Entitled "Application-Centric Cloud Computing" the discussion will focus on the concept of deploying and managing your application workloads in a shared, self-managed environment rather than manually creating and managing the application middleware topologies. It places the focus on the application rather than the infrastructure. This concept promises to deliver greater simplicity, elasticity, and
density among other things. It can position your business to react more
quickly and efficiently to the increasing demands of your customers and
free you from the managing all of the details.
Many of you may have already heard Jason speak last week at IMPACT 2011 in the cloud mini main tent or perhaps at any number of other sessions that Jason was involved in. Jason is the key architect behind IBM's WebSphere cloud activities. Obviously, Jason understands the cloud space very well and has a clear view of the evolution into Application-Centric Cloud Computing. This GWC Lab Chat will provide the opportunity to get your questions answered and share your perspective on this technology.
Jason will provide a brief introduction to the concepts and ideas and then lead an open discussion. Put it on your calendar and plan to attend - and please plan to bring your questions and comments to help foster a rich discussion. We want to hear from you.
If you haven't registered yet it is not too late - learn more and register here. It is easy to register and there is no cost. This is a very timely event and a great way to dig a little more deeply into concepts you first heard at IMPACT or perhaps hear them for the first time. Don't miss it!
In the course of my job, I am lucky to be able to work with both enterprise users and business partners who are adopting and using the WebSphere CloudBurst Appliance. When it comes to the business partner camp, one of my absolute favorites is the Haddon Hill Group. The Haddon Hill Group is an IBM Premier Business Partner, and they have been an early adopter and vocal advocate of the WebSphere CloudBurst Appliance. They have extensive knowledge of the use of the appliance in enterprise accounts, and quite frankly, they are doing some really cool things with WebSphere CloudBurst.
Given the above, I was glad to see summarized results from their various implementations made available recently on the IBM site. The summary is fairly concise, so I encourage you to take a look at the results Haddon Hill Group is getting with WebSphere CloudBurst.
I am not going to rehash the contents of the results here, but there are a couple of things I want to call out. First off, Haddon Hill Group says that WebSphere CloudBurst can provide companies with a '100 times faster time to market' delivery experience. In a practical sense, this means reducing the amount of time to deliver WebSphere environments from 40-60 days on average to just hours. That is an eye-opening data point!
The other thing I want call out here is a quote from Phil Schaadt, President and CTO, Haddon Hill Group. I have had the pleasure of working with Phil and team, and I have heard him echo these same sentiments many times:
"The important thing about the IBM WebSphere CloudBurst Appliance is that it will dispense a WebSphere Application Server image onto your WebSphere Application Server environment or private cloud along with other products within the WebSphere stack, and that application server will be ready in a few minutes. You can do it in a clustered environment, and you can even roll out IBM WebSphere Process Server and get it right in a fully clustered environment with a database connection, in about 90 minutes. You can also easily manage all the configurations of IBM WebSphere Process Server that you need. All the steps that took up so much time and effort on the part of IT staff have been removed. The savings for companies with large WebSphere implementations can be in the millions."
It is always great to see clients putting our technology to use to produce tangible business value. Again, I encourage you to take a look at these reports. As always, I am eager to hear what you think, so leave me a comment or reach out to me on Twitter @damrhein.
We've been talking a lot about IBM Workload Deployer V3 and we will continue to highlight different aspects of the capabilities it provides in the coming weeks. As we've already mentioned - IBM® Workload Deployer V3 is not just another release of the IBM WebSphere CloudBurst Appliance. While it builds on WebSphere CloudBurst's success, and supports and improves upon all of its original capabilities, Workload Deployer provides new application-centric computing capabilities for your private cloud, and brings you higher utilization, improved ease of use, and more rapid application deployment.
The WebSphere Application Server Hypervisor Edition virtual image is made up of four different virtual disks. One of those disks contains pre-created and pre-configured WebSphere Application Server profiles. When the image is activated (either through WebSphere CloudBurst or in a standalone fashion), all of the profiles not being used are deleted leaving only the intended WebSphere profile type.
Since the profiles are pre-created, this implies that certain information must be updated after the image is activated to reflect things that change with each node that is created. Among other things, the cell name, node name, and host name of the WAS profile configuration are usually updated during the image activation process. Nearly every time I talk to WAS administrators about WebSphere CloudBurst and WebSphere Application Server Hypervisor Edition they are intrigued by this particular configuration update and almost always ask "How do you do it?" (Dustin's note: Since the command to rename the cell is not officially documented, I have removed it from this post. I'm sorry, but it is for your own good!)
Most of the time this question pops up because users are attempting to, with a more narrow focus than WAS Hypervisor Edition, freeze-dry certain WAS configurations in their organization. However, no matter how they do that (virtual images, zipped up configuration files, etc.), they too need to update things like the cell, node, and host names when attempting to reuse the configuration. Many have gone down the route of trying to identify all of the different XML files they need to change in order to update this information, but this is untenable and in fact unnecessary.
If you need to update the node or host name, forget manually updating XML files. Instead, use these three wsadmin commands:
The commands can be run from a standalone node or from a deployment manager node. They are pretty straight forward, and if you need more information about them just take a look in the WebSphere Application Server Information Center. I hope this is helpful information, and stay away from those XML files!
Everybody likes having choices. This is true whether you are talking about lunch or deploying to a private cloud. When IBM Workload Deployer v3.0 was first introduced it included a pattern type for our Database-as-a-Service offering. The DBaaS PatternType v1 provided substantial value in an easy to use form factor to get a database up and running quickly and then provided the necessary tools to manage that environment. Pretty impressive for a first release! But the story doesn't end there. IBM Workload Deployer v3.1 brings an updated version of this pattern type that builds upon this foundation and adds even more capabilities and more choices.
Some of you may not be familiar with the Workload Deployer Database-as-a-Service offering so let me give you a brief introduction. Database-as-a-Service patterns allow you to define and deploy database applications into your private cloud environment with speed and consistency. These offerings also provide integrated management and monitoring capabilities. The Database-as-a-Service capability can be used in conjunction with a web application pattern (Patterns -> Virtual Applications, IBM Web Application Pattern) by including a database component in a pattern connected the web application components to use it. In this case the web application and database are deployed and managed as a unified solution with a common life-cycle as shown in the pattern below.
Database patterns can also be created and deployed as standalone entities (Patterns -> Database Patterns) that have their own life-cycle, independent of the virtual web application(s) that use the database. What's more, you can leverage these stand-alone databases from applications both inside and outside your private cloud.
Whether you use a stand-alone database pattern or one that is part of a web application pattern, the attributes and capabilities of the database are consistent.
So what is new in this release? For starters, the DBaaS PatternType has been renamed and the capabilities expanded. For Workload Deployer v3.1 the pattern is delivered as the IBM Database Patterns v1.1 and includes several elements to provide predefined configurations: the IBM Transaction Database Pattern and the IBM Data Mart Pattern.
Before we take a closer look at the new features I just want to alert you to one thing. Before you can leverage any of these new features you first need to accept the licenses and configure the plugins for the database pattern types. So look at the link and follow the directions if you would like to along and you aren't seeing the same options in your IBM Workload Deployer V3.1 system.
Using the screen shot above as a reference, let's take a look at what you can specify when creating a database pattern. You start with a name for the pattern and an optional pattern description. You also specify the maximum user data space size and an optional schema file. These are pretty basic and were all available with in the previous release. Another really nice feature that has also been available since the first release is the ability to specify a compatibility mode for DB2 and Oracle (a nice feature if you are looking to move content from existing databases).
Some of the new enhancements appear in the middle of the view; the purpose and source. The purpose specifies if this database is to be used for production or non-production (test and development). Your selection will optimize license management for deployed instances of this pattern.
The source field lets you specify a database configuration to be used to provision this database. You can choose from two different provisioning approaches; applying a workload standard or cloning from a database image. When choosing apply a workload standard you select between two predefined, optimized database configurations. These configurations will run a set of scripts to tune the operating system and instance configuration for the database. The departmental transactional standard is optimized for online transaction processing applications while the data mart standard is optimized for data mining purposes and is therefore more suitable for reporting applications. If those aren't exactly what you want but you have an existing database you can use the clone from a database image approach by selecting an existing database image backup as a model for the new database pattern. When using the clone method metadata from the backup is retrieved and a DB2 restore command is used to set the same configuration for the new database instance. Reference the cloning from a database image topic in the IBM Database Patterns information center for more details.
Once the pattern has been created you can deploy the pattern to a target cloud group or an environment profile (another new feature for database deployments in IBM Workload Deployer V3.1).
I hope you can see the value that has been added with the source configuration choices and the ability to clone an existing configuration. They are certainly substantial new features of the Database-as-a-Service solution in Workload Deployer V3.1. However, there are a number of other significant enhancements that I would just like to mention as well. In other posts we've discussed the new ability to deploy virtual applications to run on AIX with a PowerVM hypervisor. As you might expect this same ability is also available to deploy database patterns to run on AIX systems leveraging PowerVM. Management capabilities have also been significantly enhanced with the ability to configure automated database backups using the IBM Tivoli Storage Manager. These features and many other aspect of the Database-as-a-Service model are detailed in the IBM Database Patterns information center and the IBM Workload Deployer information center. My goal here has not been to replicate our product documentation - it is rather my goal to provide a few highlights and provide pointers to help you get started. I hope it has been useful.
You can be sure that we will continue enhancing and improving our Database-as-a-Service offering in IBM Workload Deployer. Please provide your feedback so that we can make it even better.
When many people think of cloud computing they immediately think of virtualization and virtual machines in particular. This is completely natural and not at all surprising. After all, one of the core underlying technologies necessary for cloud computing is virtualization. However, it is important not to confuse one element of cloud computing with the entire thing - and this can sometimes happen. Many people have begun to leverage virtual machines in their on premise environment and sometimes begin to call this their private cloud. While virtualization is a substantial step forward and help gets you started down the necessary path of standardization and automation that is essential in a cloud - it is not in and of itself "a cloud".
The National Institute of Standards and Technology has published its definition of cloud computing. This is a very complete and yet concise definition that includes not only the essential characteristics of a cloud solution but also the service models (IaaS, PaaS, SaaS) and deployment models (public, private, hybrid, community). It is a great way to get a perspective on cloud and can be useful when considering the solutions of various vendors.
Let me summarize the essential elements of cloud from this definition here:
broad network access
So, this is interesting. Not only is this much more than just virtualization - but virtualization isn't even mentioned in the list explicitly. Not to worry - virtualization is of course important and is included under the resource pooling topic. I would assert that virtualization is also necessary to facilitate the type of on-demand, self-service, elastically scaling resources that are leveraged in a cloud. What is crystal clear from this definition is that there is a lot more to a cloud solution than just virtual images and some hypervisor infrastructure upon which to run them. Somebody must provide the necessary on-demand/self-service capabilities, the network access to these services, the management of the resource pools, enabling true elasticity for running systems, measuring services and so forth. IBM Workload Deployer provides just such capabilities for the on-premise cloud allowing you to efficiently deploy patterns built for virtual systems and virtual applications with deep knowledge of the middleware that is being provisioned to optimize these solutions. Furthermore, Workload Deployer provides the complete lifecycle management from pattern creation, to deployment and provisioning, applying maintenance, resource and license management in the on-premise cloud, elastic scalability, and eventually returning resources to the on-premise cloud to be reused. Workload Deployer is a complete solution for not only server virtualization but of course for cloud computing.
However, virtualization doesn't have to stop with just virtual machines. It is a general principle that can be applied to more than just servers. At its core, virtualization is really about providing a level of abstraction between some real resources and the consumers of those resources. This is a natural fit when we think of server virtualization and virtual machines. However, there are also substantial benefits to be gained by adopting a similar abstraction between the middleware and the applications themselves - sometimes referred to as application virtualization.
By application virtualization I mean providing the capabilities to abstract the application from the underlying infrastructure such that it can be elastic, participate in health management policies, and provide agility across the pool of application infrastructure resources. This type of application virtualization is built into our Virtual Application pattern (hence the name) in Workload Deployer and surfaced in solutions via policies (such as scaling and routing), and high availability functions built into the Web Application pattern type. For Virtual Applications these features are fully integrated and optimized functions as are all elements of Virtual Applications. However, similar features have also been available for WebSphere Application Deployments in Virtual System patterns with a special extension.
WebSphere Virtual Enterprise provides application virtualization for traditional WebSphere ND solutions and this same feature is delivered for Virtual System pattern deployments of WebSphere Application Server by use of the Intelligent Management Pack. Leveraging the capabilities of Workload Deployer with Virtual Systems lets you gain the benefits of server virtualization and to reduce hardware, provide rapid and consistent deployment of entire systems, dynamically adjust resource consumption, and much more. Leveraging the capabilities of the Intelligent Management Pack provides the ability to manage service level agreements with elastic scaling and health management, lower operational costs, and provide for improved application management. These two solutions together provide a powerful combination to improve the management and resiliency of your enterprise applications.
If you would like to learn more about application virtualization using the Intelligent Management Pack in conjunction with Virtual System Patterns in IWD then please join Keith Smith and myself tomorrow for a webcast on this very topic. Keith is the lead architect on our WebSphere Virtual Enterprise and Intelligent Management Pack products and brings a wealth of experience in this space. So don't miss this opportunity - register here.
Yesterday, I had the opportunity to present WebSphere CloudBurst during the IBM Cloud computing for developers virtual event. I provided a brief overview of the appliance along with a demonstration, and then tackled some questions from the 150+ attendees in the audience.
All of the questions were good ones, and I wish I had time to address them all during the session (I will be answering all questions and posting them online soon). However, one of the questions stood out to me because of its relevance to how IBM uses WebSphere CloudBurst in their own labs. Paraphrasing, the question was "Can you share hardware resources (hypervisor hosts) between WebSphere CloudBurst and other components in your data center?"
Very good question. The answer is, of course, yes you can. I don't want to sugarcoat it because it does require thought and planning. Ideally, when WebSphere CloudBurst is using a hypervisor host, the appliance is the only thing acting on that host. However, when WebSphere CloudBurst is not using that host, then you can absolutely repurpose it for use by other components in your data center.
Our WebSphere Test Organization uses WebSphere CloudBurst to aid in their testing of our WebSphere middleware products. The capability to provision hypervisor hosts in and out of the WebSphere CloudBurst cloud is of critical importance to them. Like many organizations, they are resource constrained and must get the most out of their IT investment. They use the Tivoli Provisioning Manager to provision VMware ESX hosts for use by WebSphere CloudBurst, and then they use the WebSphere CloudBurst CLI to define those hypervisors to the appliance and do verification testing of the new resource. This allows them to easily expand and contract the amount of shared infrastructure utilized by WebSphere CloudBurst at any one time, and it means components do not have to statically lock down resources. I have a lot more information to come about our WebSphere Test Organization and their use of WebSphere CloudBurst, but I thought I would give everyone a peek at the kinds of things they do everyday with the appliance.
If you are interested in what I presented yesterday to the attendees of IBM's Cloud computing for developers event, you can check out their developerWorks Group page. In the Activities section, you will find the charts, demonstration, and a playback if you prefer to listen to the session. As always, I appreciate your feedback and questions.
Since its introduction and initial release around one year ago, activity around WebSphere CloudBurst has been a steady buzz. New images, features, enhancements have been rolling in, and can sometimes be a little overwhelming to digest. With that in mind, I want to address a related and frequent question. What products does IBM support for use in WebSphere CloudBurst?
To answer that question, we only need to look at the IBM Hypervisor Edition images currently provided by IBM. Here's a quick matrix of those images:
When I talk with WebSphere CloudBurst users, the topic of custom virtual images comes up frequently. In some cases they simply want to customize a shipped IBM Hypervisor Edition, and in other cases they want to create a completely custom image. Creating a customized version of an IBM Hypervisor Edition is relatively easy since we give you extend & capture in WebSphere CloudBurst. Creating a completely custom image has historically been a bit tougher, mostly owing ot the fact that there was not a standard tool or process for image assembly. I am happy to say that today's publication of the IBM Image Construction and Composition Tool changes all that.
Watch a demo of the IBM Image Construction and Composition Tool
The primary purpose of the Image Construction and Composition Tool is to enable a modular approach to virtual image construction, while taking into account the typical division of responsibilities within an organization. The tool allows the right people within an organization to contribute their specialized knowledge as appropriate to the virtual image creation process. This means OS teams can handle the OS and software teams can handle the appropriate software. A separate image builder can then use both OS and software components to meet the needs of users within the organization. Best of all, the image builder does not need intimate knowledge of how to install or configure any of the components in the image. They simply need to know which OS and software components to use.
When using the Image Construction and Composition Tool, you start by defining the base operating system you wish to use for your images. You can do this by importing an existing virtual image with an OS already installed, providing an ISO for the OS, or pointing to a base OS image on the IBM Cloud. The bottom line is that you have necessary flexibility to start with your certified or ‘golden’ operating system build. Once you have the base OS image defined in the Image Construction and Composition Tool, you can start defining custom software for use in the images you will compose.
In the tool, bundles represent the software you wish to install within a virtual image. The definition of a bundle contains two major parts: Installation and Configuration. The installation component of a bundle tells the Image Construction and Composition Tool how to install your software into the virtual image. You provide a script or set of scripts that install the necessary components into your image, and you direct the tool to call these scripts. These tasks run once during the initial creation of the virtual image, thus allowing you to capture large binaries, long-running installation tasks, or other necessary actions directly into your image.
The configuration section of a bundle defines actions that configure the software installed into the image. Like with the installation tasks, you provide a script or set of scripts for configuration tasks. Unlike installation tasks that run exactly once, configuration scripts become part of the image’s activation framework and as such, run during each image deployment. Using the tool, you can define input parameters for configuration scripts and optionally expose them so that users can provide values for the parameters at image deploy-time. Configuration tasks are important in providing flexibility that allows users to leverage a single virtual image for a number of different deployment scenarios.
Once you have your base OS image and one or more bundles defined in the Image Construction and Composition Tool, you can compose a virtual image. To compose a virtual image, you extend the base OS image and add any number of bundles into the new image. A base OS image plus a set of bundles defines a unique image.
After you define the image you want to construct, you initiate a synchronize action in the Image Construction and Composition Tool. When you start the synchronize action, the tool first creates a virtual machine in either a VMware or IBM Cloud environment (based on how you configured the tool). Next, the installation tasks of each bundle you included in the virtual image run to install the required software. Finally, the tool copies the configuration scripts from each bundle into the virtual machine and adds them to the image’s activation framework. This ensures the automatic invocation of all configuration scripts during subsequent image deployments.
Once the image is in the synchronized state, you can capture it. Capturing the image results in the creation of a virtual image based on the state of the synchronized virtual machine. The tool also automates the generation of metadata that becomes part of the virtual image package. When the capture of the virtual image completes, you can export it from the Image Construction and Composition Tool and deploy it using WebSphere CloudBurst, Tivoli Provisioning Manager, or the IBM Cloud.
I am excited for users to get their hands on the Image Construction and Composition Tool. I believe it represents the first big step in helping users to design and construct more sustainable virtual images. Did I mention it is completely free to download and use? Visit the Image Construction and Composition Tool website for more details and a download link. I look forward to your comments and feedback.
May is almost here and that means that IBM IMPACT is right around the corner. Just like years past, IMPACT 2010 will be a great chance to get valuable education and insight into IBM WebSphere software and software from across the IBM software family. If you want to hear how IBM software is leading the march toward a smarter planet, register now.
IMPACT 2010 will be a great chance to hear the WebSphere cloud computing story. There will be multiple sessions on the WebSphere CloudBurst Appliance. These include customer-led sessions, internal adoption stories, overviews, and much more. I'll be there running a hands-on lab and delivering a session that discusses integration between WebSphere CloudBurst and IBM Rational tools. Of course, there is more to WebSphere and cloud computing than WebSphere CloudBurst. We have several other sessions that will detail all of IBM WebSphere's work in the cloud.
If you are interested, I put together a short video discussing some of the sessions on tap for WebSphere and cloud computing at IMPACT 2010. I'd also encourage you to check out the social media site for IBM IMPACT 2010. On that site, you will find tweets, videos, and blogs about the conference. Don't forget to sign up, and I hope to see you in Las Vegas!

It does not seem like it has been a year, but here we are again. It is time for IBM Impact 2012, and like each year, this one promises to be a little better than its predecessors. As I type this post, I am 36,000 feet above either Texas or New Mexico on my way to the neon desert for a completely packed week. I can't wait to arrive!
An obvious summary of IBM Impact would be to say that it is a technology conference. That does not quite do it justice though. The event is packed full with stories of business transformation, emerging business paradigms and the technologies that support them, new product announcements and much more. That said, in my mind IBM Impact is first and foremost a premier technical education conference. The week is stuffed with technical session after technical session on a wide range of topics.
With that in mind, I thought I would share a few of the sessions I have highlighted on my calendar. To be honest, I had a hard time setting up my calendar for the week. In some cases I ended up booking three sessions in one time slot. There are simply too many good sessions to choose from, so this list is nowhere near exhaustive, and it is certainly not my full calendar!

It's here at long last! IBM PureSystems was announced today and in particular the IBM PureApplication System family member. IBM PureApplication System includes many of the capabilities that you have been hearing about and using in IBM Workload Deployer. While this solution includes and builds upon the capabilities of Workload Deployer, there's also a lot more functionality that is built into a completely integrated and optimized solution that not only manages your private cloud but runs it in the most optimized fashion. It really is a complete private cloud solution that is highly optimized to provide the best possible integration of software and hardware made simple for your cloud needs.
I hate sitting on secrets. I always have. I understand that sometimes it's in the best interest of everyone (and your job) to keep tight lips, but that does not make it any more fun. Inevitably, the run-up to our annual Impact conference means everyone in the lab is doing their fair share of secret keeping -- just waiting for announce time. For a lot of us, that day ended Tuesday with the announcement of the IBM Workload Deployer v3.0.
Now, you may be wondering, 'I have never heard of this. Why is it version 3.0??' Well, IBM Workload Deployer is a sort of evolution of the WebSphere CloudBurst Appliance, which was previously at version 2.0. This is good news for all of our current WebSphere CloudBurst users because all of the functionality (plus new bits of course) that they have been using in WebSphere CloudBurst are present in IBM Workload Deployer. You can use and customize our IBM Hypervisor Edition images in IBM Workload Deployer. You can build and deploy custom patterns that contain custom scripts in order to create highly customized IBM middleware environments. So, what's the big deal here? Two words: workload patterns.
Workload patterns represent a new cloud deployment model and are an evolution of the traditional topology patterns you may have seen with WebSphere CloudBurst Appliance (I am a little torn between evolution and revolution, but that's splitting hairs). Fundamentally, workload patterns raise the level of abstraction one notch higher than topology patterns and put the focus on the application. That means, when you use a workload pattern the focus is on the application instead of the application infrastructure. Perhaps an example would be helpful to illustrate how a workload pattern may work in IBM Workload Deployer.
Let's consider the use of a workload pattern that was part of the recent announcement, the IBM Workload Deployer Pattern for Web Applications v1.0. Just how might something like this work? It's simple really. You upload your application (maybe a WAR or EAR file), upload a database schema file (if you want to deploy a database with the solution), upload an LDIF file (if you want to setup an LDAP in the deployment to configure application security), attach policies that describe application requirements (autonomic scaling behavior, availability guidelines, etc), and hit the deploy button. IBM Workload Deployer handles setting up the necessary application middleware, installing and configuring applications, and then managing the resultant runtime in accordance with the policies you defined. In short, workload patterns provide a completely application centric approach to deploying environments to the cloud.
Now, if you are a middleware administrator, application developer, or just a keen observer, you probably have picked up on the fact that in order to deliver something as consumable and easy to use as what I described above, one must make a certain number of assumptions. You are right. Workload patterns encapsulate the installation, configuration, and integration of middleware, as well as the installation and configuration of applications that run on that middleware. Most of this is completely hidden from you, the user. This means you have less control over configuration and integration, but you also have significantly reduced labor and increased freedom/agility. You can concentrate on the development of the application and its components and let IBM Workload Deployer create and manage the infrastructure that services that application.
Having shown and lobbied a bit for the benefits of workload patterns, I also completely understand that sometimes you just need more control. That is not a problem in IBM Workload Deployer because as I said before, you can still create custom patterns, with custom scripts based on custom IBM Hypervisor Edition images. The bottom line is that the IBM Workload Deployer offers choice and flexibility. If your application profile meshes well with a workload pattern, by all means use it. If you need more control over configuration or more highly customized environments, look into IBM Hypervisor Edition images and topology patterns. They are both present in IBM Workload Deployer, and the choice is yours.
If you happen to be coming to IBM Impact next week, there will be much more information about IBM Workload Deployer. I encourage you to drop-by our sessions, ask questions, and take the opportunity to meet some of our IBM lab experts. Hope to see you in Las Vegas!
The soon to be released IBM Workload Deployer is already being integrated with many IBM products. One of these is the Rational Application Developer. I created a short video demonstration of a simple scenario that includes multiple phases of an application from development to production using IBM Workload Deployer. The scenario starts with the Solutions Architect creating a workload application pattern for a stock trading application. It then moves to the developer working in Rational Application Developer and demonstrates this integration that allows the developer to access the workload pattern, publish the application that she has built in Rational Application Developer into the pattern, and then deploy the pattern to the test cloud. All of this without leaving the Rational Application Developer user interface. The scenario then continues with the test team adding policies and validating the application before the deployment manager finally makes some final adjustments and adds places the application into the production cloud.
IBM Workload Deployer v3.1 firmware has been released and is available for download. V3.1 includes many improvements, building upon the solid foundation that was laid in V3.0 and earlier releases of WCA. There are many improvements and enhanced features. Dustin already alluded to a few of these in his previous post but let me list again here some of the more prominent new features:
The ground breaking capabilities offered in our Virtual Application Patterns have been extended to include deployments for AIX on PowerVM - giving you more choices for your private cloud environment. Along with this support a new base operating system image for AIX is also available for extension using either extend and capture or the IBM Image Construction and Composition Tool. Of course, Virtual System Patterns continue to be supported on all three private cloud hypervisors we support: VMWare, PowerVM, and zVM.
A new version of the Web Application Pattern Type (formerly WebApp Pattern Type) has been released. The Web Application Pattern Type V2.0 is built upon the feature rich WebSphere Application Server V8.0 release.
The DBaaS Pattern Type has been updated and is now the IBM Database Patterns 1.1 which includes both the IBM Data Mart Pattern 1.1 and the IBM Transactional Database Pattern 1.1 (OLTP - the default). These pattern types support a broader range of offerings for both production and non-production use. You can choose to create a new type of workload standard to apply to the DB instance or you can choose to clone an existing DB image that has been backed up to your DB image catalog repository.
A number of improvements have been made to the shared services leveraged by Virtual Application patterns. The caching service used to persist session data when scaling a web application can itself now be configured to scale, adjusting to increased demand. We have also extended the shared services to support external caching services and to leverage an external monitoring service based upon Tivoli Enterprise Monitoring Server (TEMS). You can also deploy multiple instances of shared services by deploying to multiple cloud groups.
The Plugin Developer Kit that was previously released to support building your own plugins and pattern types for Virtual Application patterns is now available for download directly from the IBM Workload Deployer dashboard - making it even easier to gain access and experience using this extension mechanism to deliver your own custom plugins and pattern types.
Images created using the IBM Image Construction and Composition Tool are now fully supported in IBM Workload Deployer V3.1 Virtual System patterns. Furthermore, the IBM Image Construction and Composition Tool is now a generally available product that is fully supported and available for download directly from the IBM Workload Deployer dashboard.
Speaking of Virtual System Patterns - a new hypervisor edition image of WebSphere Application Server V8 is now delivered with the appliance. WebSphere Application Server V8 fully supports the JavaEE6 programming model and includes many other programming models directly in the base image that were previously delivered only as feature packs including OSGi, JPA, and many more.
One item already mentioned by Dustin is the ability to configure multiple IBM Workload Deployer appliances in a master/slave relationship with a floating IP address to support continuous availability in the event that the master become unavailable. This feature can also be leveraged to support continuous operation while performing maintenance.
Another key appliance improvement is increased appliance security through the introduction of several new security roles for separation of duties. This is to ensure that no single user has unrestricted control without oversight. Among the new roles is an auditing role and auditing operations to provide data for forensic analysis of security attacks and better assist with compliance with the Health Insurance Portability and Accountability Act (HIPAA) and the Sarbanes Oxley Act (SOX).
We believe that these new features and several more make the value proposition delivered by IBM Workload Deployer V3.1 an even more compelling offering that can increase agility, consistency, and time to value for your applications.
