In keeping with the impressive release pace, WebSphere CloudBurst 126.96.36.199 is now available for download from the IBM Support site. In some ways, this release is typical of what you may expect from a service release. In other words, there are defect fixes and other general enhancements in the new version of the firmware. However, this release is a bit more than your typical service release in that there are a couple of major additions of which you should be aware.
First, starting in WebSphere CloudBurst 188.8.131.52, you will be able to provision WebSphere CloudBurst patterns to IBM Power7 systems. We already supported both Power5 and Power6 systems, and this new addition allows you to take advantage of some of the significant enhancements in the IBM Power7 hardware. In addition, this means that from a single appliance you can provision environments to multiple different releases of VMware, IBM z/VM, and IBM PowerVM hypervisor technologies. The best thing about this is that WebSphere CloudBurst provides an effective abstraction layer over the underlying infrastructure so that no matter which of the hypervisor solutions you use, the end-user experience with the appliance remains the same. You get all of this from a single device!
The other major element in WebSphere CloudBurst 184.108.40.206 is the introduction of Environment Profiles. Traditionally, WebSphere CloudBurst controlled most of the pattern deployment process. While this allows the appliance to provide a lot of configuration activity without input from the user, it made some usage scenarios hard to accommodate. For instance, historically you have not been able to assign specific IP addresses to machines in your deployment, and you have not been able to deploy a pattern across multiple cloud groups. Now, with environment profiles you can. Environment profiles give you more control over deployment behavior, including the ability to assign IP addresses (as opposed to WebSphere CloudBurst automatically doing so), deploy parts across multiple cloud groups, and apply virtual machine naming standards. The use of these new resources is completely optional, so you can still use the traditional deployment model, but this provides you with flexibility if you so choose. You can learn more about this new capability by watching the short demonstration here.
As an aside to the above information concerning WebSphere CloudBurst 220.127.116.11, I should also point out new WebSphere Hypervisor Edition announcements detailed here. I encourage you to read the announcement, but to summarize there are two major pieces of information. First, when you buy PVUs of entitlement for WebSphere Application Server Hypervisor Edition or WebSphere Message Broker Hypervisor Edition, those entitlements also apply to WebSphere Application Server and WebSphere Message Broker respectively. You can use the Hypervisor Edition images and traditional software packages in any combination, up to the level of use based on your Hypervisor Edition entitlements. Second, there is a new licensing for WebSphere Application Server Hypervisor Edition called IBM HTTP Server for WebSphere Application Server Hypervisor Edition. This allows you to deploy IBM HTTP Server instances using the WebSphere Application Server Hypervisor Edition without paying for the full Hypervisor Edition license. Again, for more details and term information, please read the announcement referenced previously.
There will be more to come about WebSphere CloudBurst 18.104.22.168, including an article on the use of environment profiles, but I wanted to give everyone a quick heads up. Let me know if you have any questions or feedback for us.
When I talk to users familiar with both WebSphere CloudBurst and the IBM Systems Director VMControl offering, there is sometimes a bit of confusion. It is not surprising. Both WebSphere CloudBurst and IBM Systems Director VMControl allow users to create and manage virtualized environments. That leads us to an oft-asked question: What is the difference between WebSphere CloudBurst and IBM Systems Director VMControl?
The simple answer is that the difference in the two offerings is the degree to which they are purpose-built. IBM Systems Director VMControl equips users with broadly applicable capabilities to create and manage environments consisting of virtual machines. These capabilities extend to PowerVM, z/VM, VMware, and Microsoft Hyper-V hypervisor platforms. IBM Systems Director VMControl is not necessarily knowledgeable about the software running in the virtual machine, but it does allow the user to manage that asset effectively.
Compare and contrast that with the capabilities provided by WebSphere CloudBurst. The appliance also enables users to create and manage environments consisting of virtual machines. The difference is that WebSphere CloudBurst is purpose-built to provide you with the ability to create, deploy, and manage virtualized WebSphere environments quickly and easily.
What does that mean? Well, on one hand it means that WebSphere CloudBurst does not treat the virtual machines it creates like a black box. In fact, it knows quite a bit about the software running inside those machines, and provides users with out-of-the-box configuration and administration capabilities for said software. WebSphere CloudBurst knows how to interact with the software in the virtual machines to do things like federate WebSphere nodes into a cell, create application server clusters, configure environments for optimal performance, apply fixes and upgrades, and more. The best part is you do not need to supply any of your own scripts to do this. In short, the appliance ships with WebSphere intelligence.
Beyond this WebSphere intelligence, WebSphere CloudBurst enables users to create customized WebSphere environments (from the operating system up) and codify those customized environments in the form of patterns. These patterns, which represent your very own WebSphere application environments, enable you to deploy your applications rapidly, repeatedly and with extremely consistent results. In addition, the appliance allows you to define varying roles for users, each of those mapping to traditional data center responsibilities (i.e. customizing the operating system, building application infrastructure, carrying out middleware customizations, etc.). Again, WebSphere CloudBurst was purpose-built with WebSphere environments in mind.
It is not all about comparing and contrasting WebSphere CloudBurst and IBM Systems Director VMControl. In the case that you are using WebSphere CloudBurst to create and manage virtualized WebSphere environments on top of the PowerVM hypervisor platform, IBM Systems Director VMControl is actually a required component. In this scenario, the two offerings are complementary. WebSphere CloudBurst communicates with IBM Systems Director VMControl in order to create and configure the virtualized WebSphere environment requested by the user. This image below depicts how the two products work in conjunction in a PowerVM environment.
I hope this helps to shed light on how WebSphere CloudBurst compares to, contrasts with, and complements IBM Systems Director VMControl. Feel free to reach out to me on the blog or on Twitter (@damrhein) with any questions I did not answer here.
A while back I co-authored an article along with Chris Ahl from Tivoli and Ken Klingensmith from WebSphere Technical Sales about the customization of virtual images in WebSphere CloudBurst. In the article we approached image customization as a means to enable IBM Tivoli Monitoring for the operating system within virtual machines dispensed by WebSphere CloudBurst. Today I posted a short demonstration that discusses and shows this particular integration scenario. If you are interested, but haven't had time to read the article, you may want to watch the video first as it should give you a good overview of the process and results.
Talk of Tivoli reminds me that IBM Pulse 2010 is just around the corner. I'll be going to discuss WebSphere CloudBurst and how it can be paired with software from IBM Tivoli for high-value integration scenarios. In the session I'll be talking about the Tivoli Monitoring integration as well as other key points such as our integration with Tivoli Service Automation Manager, IBM CloudBurst, and more. The best part about the session is that I will be co-presenting alongside a WebSphere CloudBurst customer that will dole out practical advice for using WebSphere CloudBurst within the enterprise. Join us on Tuesday February 23rd from 3:30 - 4:30 in Conference Center 306.
Remember, any time you have questions about WebSphere CloudBurst please pass them along. You can leave comments on this blog, or you can reach me at my new Twitter location @damrhein.
I was very encouraged by the consistently positive response we got at IMPACT for our WebSphere CloudBurst and Rational Automation Framework for WebSphere (RAFW) integration. I believe there were many reasons for this response: accelerated time to value, decreased investment needs for activities that are not core to your business, lowered barrier of entry for provisioning and configuring WebSphere cells, and much more. While those are certainly all very real and valuable benefits, I also believe that quite a bit of interest in this integrated solution comes from the fact that it is applicable to a number of needs common to you, our WebSphere users.
With that in mind, let's look at some (not all) of the scenarios where WebSphere CloudBurst and RAFW integration can help you:
Create WebSphere CloudBurst patterns that include configuration without scripting: Users love our WebSphere CloudBurst patterns. They really see the value in codifying both the topology and configuration of their application infrastructure. However, some users do not have existing WebSphere configuration scripts and do not have the time and/or resource to invest in creating these scripts. They are looking for a solution that provides not only the provisioning of WebSphere environments but also the configuration of said environments (configuration beyond what our IBM Hypervisor Edition images encapsulate, specifically application-oriented configuration). RAFW provides this capability in the form of 500+ out-of-the-box configuration actions for WebSphere environments. This includes actions to create JDBC resources, create JMS queues, deploy applications, configure application containers, and much, much more. You can create WebSphere CloudBurst patterns that contain a special script package, which points back to a RAFW project containing a set of configuration actions. During deployment, WebSphere CloudBurst will provision your WebSphere environment and then cause the invocation of the specified RAFW project, which in turn runs a set of configuration actions against the provisioned environment. This means you can set up full-blown, ready-to-go application environments with absolutely no user-supplied scripting. In fact, I took this approach to setup a J2EE performance benchmark application, DayTrader 2.0, running on WebSphere Application Server. Those of you familiar with the application know this is not a trivial environment to stand up. Yet, I did it without having to personally write a single line of configuration scripting, and it was all ready to go in around thirty minutes.
Creating WebSphere CloudBurst patterns from existing environments: This comes up all the time. I go through a standard introduction to WebSphere CloudBurst, users see the value, love the patterns-based approach, and immediately want to know how they get their existing environments into the form of a pattern. RAFW, along with the special WebSphere CloudBurst script package, can make this a straightforward and hardened process. You use a capability in RAFW to import the configuration of an existing cell, thereby creating a RAFW environment for that configuration. You then create a WebSphere CloudBurst pattern with a topology congruent to your existing environment, attach the special script package I mentioned earlier, and you are done with the import! When you deploy this pattern, you simply specify the RAFW environment that you created earlier (the one that holds the configuration data for your existing environment) and a RAFW project that will apply the configuration data in that RAFW environment to the WebSphere environment provisioned by WebSphere CloudBurst. The creation of the WebSphere environment, as well as its configuration, happens in a completely automated fashion.
Configure, capture, reuse: There are many situations that may require you to make manual changes to a WebSphere cell after it has been deployed. For example, during performance testing for your application, you might discover that you need to tweak the number of available threads in the web container. As another example, for the first setup of a given application environment, you may want to quickly deploy the cell using WebSphere CloudBurst and then manually install and configure your applications to make sure everything is just right. In either case, it is likely that you want to capture the updated configuration and make sure that any future deployments use those updates. Again, WebSphere CloudBurst and RAFW makes this simple. First, you build a pattern that encapsulates your WebSphere topology (the types and quantity of nodes you want) and attach the special script package mentioned above. For the first deployment, you simply specify the name of the new RAFW environment you want to create. Once the system is up, you log into the WebSphere administration console, make your necessary customizations, and then you use RAFW to import that updated configuration thus updating the initially created RAFW environment. For subsequent deployments, you simply deploy the same pattern, specifying the same RAFW environment as well as a RAFW project, which RAFW automatically created for you during the first deployment. This project applies the configuration (the one you manually established and imported into RAFW) to the WebSphere environment setup by WebSphere CloudBurst.
Configure WebSphere environments across virtual and physical settings: It seems that in many cases our users manage the same WebSphere environment across both virtual and physical settings. For example, they may provision the application environment using WebSphere CloudBurst for everything from development to pre-production, and then for production provision that same environment to a set of physical servers. At least, they try to provision the same environment. In reality, it is tough to reproduce the exact same configuration once you break from the WebSphere CloudBurst patterns-based approach. However, if you stored the configuration of your WebSphere cell as a RAFW environment, you could apply that configuration data to a WebSphere cell regardless of whether it existed in the physical or virtual world. Once you move to physical, you do lose out on the fast provisioning, WebSphere intelligence, cloud management capabilities, and automated integration with RAFW that you get when using WebSphere CloudBurst, but if it is in your process to move to physical hardware at some point, reusing the same RAFW environment certainly eases the migration task.
I hope this sheds some light on some of the common issues WebSphere CloudBurst and the Rational Automation Framework for WebSphere can combine to solve really well. This is by no means an exhaustive list, but really meant to point out the broad application of the solution. If you want to see how it works, check out this video.
Since the IMPACT conference, there has been quite a bit of buzz around the new features, capabilities, and enhancements coming in WebSphere CloudBurst 2.0. In addition to the updates for the appliance, there are some updates to the IBM Hypervisor Edition virtual images as well. In particular, there is one new offering that I want to make sure is getting more than a mere 15 minutes of fame.
What is this new offering that deserves some time in the spotlight? Well, it is the Intelligent Management Pack for the WebSphere Application Server Hypervisor Edition. Still not sure what this is? Simply put, it is an optional add-on to the WebSphere Application Server Hypervisor Edition that enables WebSphere Virtual Enterprise capabilities in the environments dispensed by WebSphere CloudBurst.
If you are not familiar with WebSphere Virtual Enterprise, this still may not mean much yet. Essentially, the use of the Intelligent Management Pack means you create environments that contain capabilities to dynamically manage your application runtime environment. This includes, but is not limited to, the following capabilities:
Dynamic clustering: Create WebSphere Application Server clusters whose membership changes autonomically in order to meet the needs of your applications. You create service level agreements to define the needs for your applications.
Application health monitoring: Monitor the health of your applications by assigning health policies. These policies designate the condition to monitor for (i.e. memory leaks), and they dictate what action to take in case the condition occurs (i.e. restart the server).
Application editioning: Manage multiple versions of your applications and roll out new versions of your applications without incurring downtime. This is essential if you consistently deliver updates to your applications deployed in production environments.
On-Demand routing: Build WebSphere CloudBurst patterns that include On-Demand Router parts. On-Demand Routers are a key component of WebSphere Virtual Enterprise environments and act as an enabler of some of the functionality discussed above.
If you are a user of WebSphere Virtual Enterprise, or otherwise knowledgeable with the product, the Intelligent Management Pack should be pretty familiar to you. When you deploy a pattern built from WebSphere Application Server Hypervisor Edition with the Intelligent Management Pack, you end up with a WebSphere Virtual Enterprise cell. When you log into the administration console, you will see the WebSphere Virtual Enterprise console. You can use any of the features in the normal WebSphere Virtual Enterprise product in the environment created by WebSphere CloudBurst.
Be on the lookout for more information concerning the Intelligent Management Pack. I know there is an article in the works, and we will also be working on some short demos for our YouTube channel. In the meantime, please reach out to me here or on Twitter (@damrhein) with any questions or comments.
The 1.1.1 version of WebSphere CloudBurst is now available on the IBM support site, and you can read a bit about it here. I have not blogged about each and every point release of WebSphere CloudBurst here, but this particular one is significant. The 1.1.1 release adds support for IBM's z/VM hypervisor platform as a deployment target.
Quite simply this means that you can now create virtualized WebSphere application environments on the z/VM platform using WebSphere CloudBurst. This starts by first defining target hypervisors, instances of Linux Master Systems, that WebSphere CloudBurst can communicate with to setup virtual machines on z/VM. Coupled with support for the z/VM infrastructure components, there is a new version of the WebSphere Application Server Hypervisor Edition virtual image. While this new image contains the same basic components as the previous hypervisor edition images, it is packaged for the z/VM platform, and it includes a zLinux operating system.
Once you upgrade to WebSphere CloudBurst 1.1.1, you can define your z/VM infrastructure and use the new WebSphere Application Server Hypervisor Edition image to build custom patterns targeted for the z/VM platform. I put together a demonstration that provides a very brief overview of these new capabilities. As always, please reach out if you have any questions about this or any other WebSphere CloudBurst topic.
For those of you attending IBM Impact 2009 next week (May 3rd - 8th) in Las Vegas at the Venetian Hotel, I thought I would tell you about some opportunities to hear about the new WebSphere CloudBurst Appliance.

IBM Intelligent Management - Overview demonstration - Booth #3
The more and more we visit with customers about our new WebSphere CloudBurst Appliance, the more we see a common thread of questions emerge around the offering. In an attempt to address some of these questions in a more accessible medium, I figured I'd start a series of blogs that relays some of these questions and of course the answers. Today I want to start with what is perhaps the most frequently asked question about WebSphere CloudBurst.
One thing I've noticed while talking to customers is that virtualization and virtualization management tools are widely used today. When we talk to customers already using these tools, they immediately understand the benefits WebSphere CloudBurst delivers in the form of virtualizing WebSphere Application Server environments and bringing a set of lifecycle capabilities to this virtualization. However, almost invariably they ask why they would use WebSphere CloudBurst over their existing tools, for instance VMware's vSphere offering.
There's a two-word answer to this question: WebSphere intelligence. What exactly does that mean? WebSphere CloudBurst was built with WebSphere in mind, and it knows how to configure, tune, and maintain WebSphere Application Server environments without the need for custom scripting.
For instance, when a user is building a WebSphere CloudBurst pattern (if you are wondering what a pattern is, or just want to learn the basics of WebSphere CloudBurst, take a look at this article) the relationships among the various WebSphere Application Server parts are automatically configured. This means that custom nodes are automatically federated into the Deployment Manager cell, web servers are automatically configured to route to application server nodes (and the web server's config file is setup to be automatically propagated), and much more. In addition to establishing these relationships, WebSphere CloudBurst also applies best practice tuning to the WebSphere environment. This tuning of course is just a suggestion and can be easily changed by users.
In addition to configuring and tuning a topology, WebSphere CloudBurst allows users to apply both fixes and service level upgrades to running virtual systems. Through the console, users can select virtual systems and apply either a fix or upgrade directly to the system. All the while, WebSphere CloudBurst automatically backs up the state of the system before the change is applied, and users can easily roll back to the previous system state if undesired behavior is encountered after the change.
I'm not disputing that all of these actions could be potentially accomplished using some "black-box" virtualization management tool, but the burden of supplying WebSphere intelligence is placed directly on the user. In order to configure, tune, or maintain virtualized WebSphere Application Server environments, users would accompany their virtual machine definitions with a heavy dose of scripting. These scripts only add to the pile of IT assets that need to be owned, updated, and maintained over time, and they only serve to distract users from the end-game of getting their applications up and running.
It's important to note too that WebSphere CloudBurst was only just released, so I would expect that the WebSphere intelligence it provides will only grow and get better over time. If you want to learn more about WebSphere CloudBurst, or if you think your company would be interested in a briefing and demo please get in touch. You can reach me at email@example.com. We would love to explain both the business value and technical capabilities of the appliance.
To continue with the series of blog posts regarding WebSphere CloudBurst FAQs, I want to take a look at one aspect of the deployment process.
When you leverage WebSphere CloudBurst to push patterns (complete WebSphere Application Server configurations) into a private cloud, the appliance provides an advanced placement algorithm to determine exactly where the resulting WebSphere virtual systems will reside. It attempts to match the needs of the pattern to the correct set of hypervisors that have been defined. WebSphere CloudBurst considers things like storage, CPU, memory, and high availability characteristics when placing the pattern, and this is all done by the appliance without you having to intervene at all.
This is certainly nice in that it absolves you from having to make such placement decisions. Having said this though, you may be thinking of a question that comes up quite often:
If WebSphere CloudBurst controls the placement of the pattern, how can I make sure that certain deployments end up on certain servers (hypervisors)?
Considering what I just told you above, it may not seem that it's possible to control what machines end up hosting your virtual system since the appliance takes care of that placement for you. However, the organized use of WebSphere CloudBurst cloud groups allows you to take advantage of the intelligent placement provided by the appliance while retaining a level of control over which machines end up hosting particular deployments.
In WebSphere CloudBurst all patterns are deployed to cloud groups. Cloud groups are a collection of hypervisors that have been defined within the appliance. The basic deployment mapping is depicted in the image below:
As seen above, you can create a cloud group for any purpose (dev, test, QA, production, etc.), including any hypervisors that you desire as long as a given hypervisor only belongs to a single cloud group. When you are ready to deploy a pattern, you simply select the cloud group you want to deploy to:
By selecting a cloud group for deployment, you are implicitly selecting the physical machines that will host your deployment. The cloud group could consist of anywhere from one to N hypervisors, so you are afforded the ability to restrict the location of your virtual systems as necessary.
I hope this helped explain a little bit about cloud groups in WebSphere CloudBurst. If you're looking for more information about WebSphere CloudBurst cloud groups, I'd also suggest you watch this video on our YouTube channel.
I want to stay in the realm of the deployment process for our next frequently asked question regarding the WebSphere CloudBurst Appliance.
The ability to quickly deploy entire WebSphere Application Server cells (anything from single node cells, to multi-node clustered cells) is a hugely compelling feature of the appliance. Instead of spending days or hours deploying a WebSphere Application Server cell, users can deploy these in a matter of minutes (less than twenty minutes for clustered environments)!
For the most part, WebSphere CloudBurst patterns represent entire cells. This includes management parts (AdminAgent, DeploymentManager), managed parts (custom nodes), and proxy parts (IHS). When you deploy a pattern, the result is a complete and fully functional WebSphere Application Server cell running in your private cloud.
So, now that you have a complete cell out in your cloud, what happens if you need to add more nodes? If the the user-demand for the applications on your cell has exceeded the initial topology, can you use WebSphere CloudBurst to add more cells? Sure you can!
In short, this involves creating a pattern that contains only a custom node part, and then at deploy time, providing information about the existing cell. WebSphere CloudBurst then takes over the deployment of that custom node and federates the node into the existing cell based on the information supplied about that cell. I won't go into an entire explanation here, because I think the demo I put on our YouTube channel explains it pretty well.
In my experience with the WebSphere Application Server, this represents a much more seamless and automated process for deploying new nodes into an existing cell than what exists outside of WebSphere CloudBurst today. Of course, we value your comments and feedback above all else. So let us know what you think!
