Yesterday, we kicked off a WebSphere in the Clouds campaign designed to connect you with IBMers that can help you to leverage WebSphere solutions to build clouds. The campaign consists of webcasts, podcasts, live Q&A sessions, and online JAMs. You can listen to replays and sign up for upcoming events by visiting the Global WebSphere Community website.
Next week, the campaign delivers a series of podcasts that discuss the WebSphere technologies that form the building blocks of clouds. These podcasts will discuss both the business and technical aspects of these solutions, and they will cover topics like application infrastructure in the cloud, policy-based workload management using application virtualization, hybrid cloud integration, and more. Over the past few days, I had the opportunity to catch up with the various presenters of these podcasts to ask them a few questions about their solutions. These interviews provide a nice sneak peak at what is coming in the podcasts, and I will be posting them here in the coming days.
To kick things off, I'm posting a video interview with Marc Haberkorn. Marc is the WebSphere Product Manager for WebSphere CloudBurst, WebSphere Application Server Hypervisor Edition, and WebSphere Virtual Enterprise. My colleague, Ryan Boyles, caught up with Marc and got his thoughts on how these solutions enable virtualization and automation for your cloud environments. Enjoy!
Over the past several months industry focus on cloud computing seems to have only intensified. Within IBM and for the purposes of this blog, WebSphere, there have been several announcements and offerings that indicate our commitment and belief in the cloud computing approach.
To further highlight WebSphere's focus and offerings in the cloud computing realm, we are embarking on a "WebSphere in the Clouds" campaign during the months of September and October. Our intent is to virtually deliver information about our cloud strategy and offerings directly from the experts to you, our WebSphere users.
The event will be kicked off by WebSphere's Director of Product Management, Kareem Yusuf, on September 23rd from 9-10 EDT. Kareem will talk about cloud computing in the enterprise, and its unique relationship to SOA thoughts and principles. In addition, he'll give an overview of what WebSphere has been doing in the cloud computing space. This will be followed by sessions from technical experts that detail WebSphere offerings in both the public and private clouds, as well as sessions that discuss enablers of application and application infrastructure elasticity.
To find out more about the "WebSphere in the Clouds" campaign, you can check out the main announcement page. To sign up for the series of virtual events visit the registration page. We hope you will join us for the series of webcasts to learn all about WebSphere's work in the clouds.
Though I feel like we've come a long way in some of the initial confusion surrounding IBM CloudBurst and WebSphere CloudBurst, I still get quite a few basic questions on the solutions. The two most common questions are, 'Are they different products?', and 'Can/should I use them together?'. I put together a really brief overview that answers these questions and talks about the basics of the combined solution. I hope it provides a good introduction!
A recent announcement signaled the coming release of WebSphere CloudBurst 1.1. This new release of the WebSphere CloudBurst Appliance delivers enhancements to all phases of the lifecycle of virtualized WebSphere Application Server environments. Let's take a closer look at a few of these updates.
First and foremost, WebSphere CloudBurst 1.1 delivers support for the PowerVM platform. You can now deploy patterns to create virtualized WebSphere Application Server environments running in a PowerVM environment on pSeries servers. Among other things, this is enabled by a new version of the WebSphere Application Server Hypervisor Edition. This new version of the virtual image contains an AIX operating system and has been specifically bundled to allow it to be activated on the PowerVM hypervisor. From a user standpoint, building, deploying, and maintaining WebSphere Application Server environments is done from the same console with the same look and feel regardless of the target platform. Check out this demo to see WebSphere CloudBurst and PowerVM in action.
In addition to support for PowerVM environments, WebSphere CloudBurst 1.1 will also provide a trial edition of a DB2 virtual image. You can import this image into your WebSphere CloudBurst catalog and then use it to build and deploy DB2 environments. This allows you to, from the same centralized interface, deploy and integrate both your application and data environments in your private cloud. Check out this demo for more information on the new DB2 trial virtual image for WebSphere CloudBurst.
One other cool feature I want to point out delivers an enhancement to the use of script packages in WebSphere CloudBurst. In this new version of the appliance, you have more control around when script packages you include in a pattern are executed. Previously, these were executed toward the end of pattern deployment once all the necessary WebSphere Application Server components had been started. While that is still the default behavior, you can also elect to have the script package invoked when the virtual system is deleted, or you can choose the invocation to be user-initiated meaning that you decide when and how many times your script runs. To check out a pretty handy use case for this feature, watch the demo here.
These aren't the only new features and enhancements delivered in WebSphere CloudBurst 1.1. Stay tuned for more demonstrations and more words about these new features and when and why you would want to use them. In the meantime, if you have any questions be sure to stop by our forums.
In keeping with the impressive release pace, WebSphere CloudBurst 188.8.131.52 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 184.108.40.206, 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 220.127.116.11 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 18.104.22.168, 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 22.214.171.124, 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.
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.
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.
