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.
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!
Over the last three posts I've been discussing a few of the most frequently asked questions regarding the WebSphere CloudBurst Appliance. I'd like to wrap up today with a fourth and final installment.
If you have read some of my entries before, or if you have read any of our WebSphere CloudBurst articles on IBM's developerWorks, then you know that the appliance brings extreme simplification and safety to applying fixes and service level upgrades to running WebSphere Application Server virtual systems. Users select a virtual system, choose a fix or service level upgrade, and then WebSphere CloudBurst drives the application of the fix or upgrade to the system. Before applying the fix or upgrade, the appliance takes a snapshot of the virtual system, and users can simply click a button to roll back to the previous state if the process produces undesired results.
This is a pretty strong value add to WebSphere Application Server management and one that our users typically immediately understand. Almost always though, after users see this they are curious about another aspect of rolling out fixes and upgrades in WebSphere CloudBurst. In particular, they want to know how they ensure that all subsequent deployments (after applying the fix to a specific virtual system) can be ensured of having the correct fixes and service levels.
The answer to this inquiry is that there are a couple of different ways to achieve this, and it depends on what you are try to accomplish and your preferences. For instance, if you want to make sure all of your subsequent deployments have a particular interim fix, you will likely go the route of image extension. First, you pick the WebSphere Application Server Hypervisor Edition image in your catalog to which the fix applies. Next, you extend that image, and once a virtual machine based off the image is accessible, you use existing WebSphere Application Server tools (Update Installer) to apply the fix. After the fix has been applied, you can capture the updated image and then use it as the basis for patterns created from that particular version of the WebSphere Application Server.
On the other hand, if you are looking to ensure subsequent deployments are based on a new level of the WebSphere Application Server, your process will be a bit different. First you would load a new WebSphere Application Server Hypervisor Edition image (based on the new level of WebSphere Application Server) into your WebSphere CloudBurst catalog. Then you would select any of your customized patterns you wanted to upgrade to the new level, clone that pattern, and simply select the new image as the basis for the pattern. All of your other customizations are preserved. Really, it's that simple!
I hope that over the last month I have answered some of the more common questions about WebSphere CloudBurst. At any point if you have any questions feel free to email me or leave a comment right here on the blog.
It's about the time of year when we all look back and try to determine exactly how we spent the past twelve months. Whether we do it because we have to as part of year-end job reviews or because we like to take stock in what we've done and figure out where to improve next year, it's a time for reflection and recall. For me, this exercise made me take a look at various things we have done to deliver WebSphere CloudBurst technical collateral (articles, demos, blogs, etc.) in 2009.
For all practical purposes, our mission and efforts for such technical collateral for WebSphere CloudBurst started when it was announced at Impact in May of this year. Though there was certainly some preparatory work being done on this front, there was nothing we could really push to the public until after the announcement, and in some cases even after the appliance's release in June. Given that most of the content was produced over a six month stretch, I really think we put forth a strong effort, and I hope that this technical material has helped to both raise awareness of and educate users on the WebSphere CloudBurst Appliance.
Seeing as I already went back and rounded up this content, I thought I'd provide you a centralized look at the information. To start, I accounted for the articles that we published to the IBM developerWorks site over the six month stretch. All together I counted 8 articles and a special column entry:
As you can see the articles cover quite a bit of content and range from general level overview articles to technical in-depth "how-to" style articles. In general they seem to have been received well with over 26,000 views to this point. Our goal is to keep the pace up for 2010, and we already have a few articles on our plate for early in the new year (including an overview of what's new in WebSphere CloudBurst 1.1).
Another main medium we utilized to spread the word about WebSphere CloudBurst was YouTube. On our YouTube channel at http://youtube.com/websphereclouds, we currently have 17 different videos that demonstrate how to use certain features of the WebSphere CloudBurst Appliance. Though I think each demo provides value depending on exactly what a viewer is looking for, 3 of them really stick out for me.
Check out our videos if you get a chance. We've made an effort to keep them as short as possible while still providing value to viewers.
We have some WebSphere CloudBurst content spread around other places as well including this blog and my personal blog. Over the next few weeks we'll be taking a look at what worked and didn't work with respect to getting information out to the public. Of course at any time we very much appreciate your feedback on how you like to see content delivered because you are our target audience! If you have a comment, idea, or suggestion, leave a comment on the blog or send me a tweet to @WebSphereClouds.
If you've attended one of our WebSphere CloudBurst sessions then you've undoubtedly heard us talk about the "special sauce" or "WebSphere intelligence" delivered by the WebSphere CloudBurst Appliance. If you haven't attended one of our sessions, trust me, we talk about it a lot, but there's good reason. This "special sauce" truly sets WebSphere CloudBurst apart from other virtualization management tools.
Essential to the uniqueness of the WebSphere CloudBurst solution is the WebSphere Application Server Hypervisor Edition virtual image that it dispenses. In one sense, the intelligence comes in the format of pre-installed, tuned, and configured software. The operating system and WebSphere components are all pre-installed, and the WebSphere Application Server configuration is tuned based on best performance practices. In addition, the image comes with a pre-configured instance of each WebSphere Application Server profile type that is available in the version that is bundled. This saves time during deployment since the unneeded profiles are simply removed.
The pre-installed, tuned, configured software only sets the foundation for what truly sets apart the WebSphere CloudBurst solution. The activation framework built inside of the WebSphere Application Server Hypervisor Edition allows WebSphere CloudBurst to deliver unique value. This activation framework allows the single virtual image to turn into many different flavors of WebSphere Application Server (Dmgrs, Standalone nodes, Custom nodes, Job Managers, etc), and it provides the facilities to change WebSphere cell and node names, IP addresses, host names, and more while a running virtual machine instance is being created.
On a mostly unrelated topic, the changing of WebSphere cell names, node names, host names, is done with documented, publicly available commands in either wsadmin or other WebSphere Application Server binaries. I know many customers want to do this exact same thing in their existing environments, so if you are wondering how it is done, drop me a line below.
Anyway, I won't get into anymore detail here because you can get a much better assessment of this special sauce elsewhere. Ruth Willenborg, one of the lead architects for the WebSphere CloudBurst Appliance, did a developerWorks Comment lines piece about this special sauce. Ruth provides a deeper look at the topics I hit on above, and it's a really good read. You can check it out for yourself here.
Every time I've visited with customers about WebSphere CloudBurst, without fail someone requests that the appliance support products besides the WebSphere Application Server. We started to address these requests with WebSphere CloudBurst 1.1 when we announced the availability of a DB2 Enterprise 9.7 trial virtual image specifically packaged for use in the appliance. Very recently we continued to respond to customer requests by extending the list of supported products in WebSphere CloudBurst to include WebSphere Portal.
The WebSphere Portal Hypervisor Edition, initially offered as a Beta product, is a virtual image packaging of WebSphere Portal 6.1.5 ready for use in the WebSphere CloudBurst Appliance. The image includes a pre-installed, pre-configured instance of WebSphere Portal. Also contained within the image is an IBM HTTP Server instance configured to route to the WebSphere Portal instance and a DB2 instance installed and configured as the external database for WebSphere Portal. The WebSphere Portal instance also includes Web Content Management enablement along with several samples to help users get started right away.
The user experience when building and deploying WebSphere Portal patterns remains consistent with the existing experience for WebSphere Application Server and DB2 patterns. Another good note is that you can expect similar rapid deployment capability for WebSphere Portal patterns. I got a running virtual system, with all the parts I mentioned above installed and configured (meaning no after the fact integration scripting was necessary) in under 15 minutes.
To see more, check out my new demonstration of the WebSphere Portal Hypervisor Edition for the WebSphere CloudBurst Appliance. If you have a WebSphere CloudBurst Appliance you can download the WebSphere Portal Hypervisor Edition image and a usage guide from here.
One of the most exciting announcements at IBM IMPACT last week was that of the new WebSphere Process Server Hypervisor Edition. This new virtual image allows you to provision complete WebSphere Process Server environments into your on-premise cloud using the WebSphere CloudBurst Appliance. Just like with the other environments you can provision using WebSphere CloudBurst (namely WebSphere Application Server, DB2, and Portal Server), you can stand up these WebSphere Process Server environments in a matter of minutes.
The WebSphere Process Server does not come pre-loaded on the appliance, but it does come with a cool utility that helps you get it on the appliance. The WebSphere Process Server Hypervisor Edition loader provides a wizard-like tool that loads the image into the catalog of an appliance you specify. The tool is simple to use and is included as part of the image package that you download from Passport Advantage.
Not only does the loader above populate the WebSphere Process Server Hypervisor Edition into the appliance's catalog, but it also creates a set of patterns for the WebSphere CloudBurst Appliance. These patterns encapsulate golden topology environments for WebSphere Process Server Hypervisor Edition. At the time of my post, the patterns created by the loader include the following:
Standalone server: This pattern represents a single server instance of WebSphere Process Server. Deployment of the pattern results in a single virtual machine that contains both the server instance and a DB2 instance.
Simulated environment: This pattern contains a single part called a 'Full function control node'. Deployment of the pattern results in the creation of a deployment manager, proxy server, DB2 environment, and three WebSphere Process Server clusters (application target cluster, support cluster, and messaging cluster), all in a single virtual machine.
Scalable environment: This pattern contains a deployment manager, 'Basic function nodes' part, DB2 part, and a proxy server. Deploying the pattern results in the same components as the pattern above, but in this case each component resides in its own virtual machine.
The announcement of the WebSphere Process Server Hypervisor Edition only serves to increase the applicability of WebSphere CloudBurst for constructing on-premise WebSphere clouds. If you have any questions, or want to learn more about this new virtual image, please let me know.
Looking for a reminder of the difference a year can make? If so, just take a look at the last year or so for the WebSphere CloudBurst product. Since about this time last year, we have seen the release of versions 1.1, 1.1.1, 2.0, and 220.127.116.11, each one bringing their own set of major enhancements and features. Owing to this aggressive pace, it is sometimes easy to miss out on the latest capabilities of the product. For that reason, I wanted to give a brief rundown of some (definitely not all) of the major additions to WebSphere CloudBurst over the past year.
PowerVM and z/VM support: WebSphere CloudBurst 1.1 introduced support for PowerVM (based on Power5 and Power6 systems), and version 1.1.1 introduced support for z/VM. This means that a single WebSphere CloudBurst Appliance can provision to VMware, PowerVM, and z/VM virtualization platforms.
Power7 support: WebSphere CloudBurst 18.104.22.168 introduced support for Power7 systems, thus allowing users to take advantage of the significant enhancements provided by Power7 via WebSphere CloudBurst deployments.
Expansion of the IBM Hypervisor Edition portfolio: The portfolio of images that you can deploy using WebSphere CloudBurst now includes WebSphere Application Server, WebSphere Process Server, WebSphere Portal Server, WebSphere Business Monitor, WebSphere Message Broker, and DB2. In addition to adding new images, we also expanded the platform and operating system support for existing images. For example, you can take advantage of the Red Hat Enterprise Linux OS for WebSphere Application Server Hypervisor Edition, and you can deploy WebSphere Process Server Hypervisor Edition to z/VM infrastructure.
Addition of the Intelligent Management Pack: The Intelligent Management Pack is an optional feature of the WebSphere Application Server Hypervisor Edition that allows you to take advantage of autonomic, policy-driven runtime management capabilities in your deployed environments. This includes the ability to create proactive health policies for your environments, assign SLAs to your applications, manage the update of applications, and more.
License management capabilities: In WebSphere CloudBurst version 2.0 and later, you can make use of license monitoring and management functionality. This allows you to get both point-in-time and historical views of software PVU usage within your cloud, and it allows you to setup policies concerning the usage of PVUs for WebSphere CloudBurst deployments.
Environment profiles: WebSphere CloudBurst provides quite a bit of out-of-the-box deployment automation in terms of selecting hypervisors, assigning IP addresses, and more. However, sometimes you need more control over exactly how this happens. WebSphere CloudBurst 22.214.171.124 introduced environment profiles that you can use to exercise more control over how deployment happens in WebSphere CloudBurst.
In my view, this is quite an impressive list of features delivered within a year's time. I should also reiterate that this is by no means a complete list, but just a selection of some of the major enhancements during this time. If you have any questions about the above additions, or if you have any questions on other features, please let me know.
