If you are going to install and use WebSphere CloudBurst in your own environment, it is very likely that you would want at least two appliances. Perhaps you want to have a standby appliance in case of a failure on the main appliance, or maybe you have different teams that are looking to utilize the appliance in different data centers. In any case, once you install multiple appliances there's another requirement that will pop up pretty quickly. Naturally you are going to want to share custom artifacts among the various WebSphere CloudBurst boxes.
When I say custom artifacts, namely I mean virtual images, patterns, and script packages. Script packages have been easy enough to share since WebSphere CloudBurst 1.0 because you can simply download the ZIP file from one appliance and upload it to another. However, there are some enhancements in WebSphere CloudBurst 1.1 that make it easy to share both patterns and images among your different appliances.
As far as patterns go, there is a new script included in the samples directory of the WebSphere CloudBurst command line interface package called patternToPython.py. This script will transform a pattern you specify into a python script. The resulting python script can then be run against a different WebSphere CloudBurst (using the CLI), and the result is the pattern is created on the target appliance. You need to be sure that the artifacts that pattern references (script packages and virtual images) exist on the target appliance and have the exact same name as they do on the appliance from which the pattern was taken. There are no other caveats, and this new sample script makes it really simple to move patterns between appliances.
For virtual images, a new feature was added that allows you to export a virtual image from the WebSphere CloudBurst console. Simply select a virtual image, specify a remote machine (any machine with SCP enabled), and click a button to export the image as an OVA file. This OVA file can then be added to another WebSphere CloudBurst catalog using the normal process for adding virtual images. You can see this feature in action here.
Stay tuned for more information about some of the handy new features in WebSphere CloudBurst 1.1. We also should have a comprehensive look at the new release coming soon in a developerWorks article.
I want to clear something up about WebSphere CloudBurst that can sometimes cause a bit of confusion. In nearly all of our content about the appliance, we talk about it in the context of building private clouds consisting of WebSphere application environments. Typically people think of private clouds as something only those within their organization can access and utilize. However, with WebSphere CloudBurst you are not limited to creating that kind of a private cloud.
Perhaps it is more fitting that we talk about WebSphere CloudBurst as a means to create on-premise clouds. After all, that's really what we mean. You create a shared pool of hardware and network resources owned by your organization, and then you define this cloud of resources to WebSphere CloudBurst. Once that cloud is defined, you can leverage WebSphere CloudBurst to dispense your WebSphere application environments into that cloud. The accessibility of your application environments running in that cloud is entirely up to you.
You may decide that the cloud is indeed private and that only those in your organization or a smaller subset of users can access the environments. On the other hand, you may decide that you want to allow consumers in the public domain to request WebSphere application environments and then have WebSphere CloudBurst provision those environments into a public cloud. I say public here because while the cloud's resources are on your premise, access to that cloud is not restricted to within the organizational firewall. Ultimately, the determining factor for whether or not your WebSphere CloudBurst cloud is public or private is the network configuration you provide. If the virtual machines are associated with network resources that are publicly accessible, then I would say you have a public cloud.
I hope this entry didn't serve to only add to the confusion. The bottom line is this: WebSphere CloudBurst allows you to create, deploy, and maintain virtualized WebSphere environments in an on-premise cloud. Whether that cloud is public or private is entirely up to the network configuration that you setup.
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.
Users of cloud computing solutions today expect to be charged for exactly the amount of compute resource they use. No more, no less. This expectation is often at the forefront of our customers' minds when contemplating the creation of internal or private clouds. They want to be sure that any solution they use audits the activity and usage of their cloud and enables them to consume this information to implement their specific chargeback scheme.
Thought it's not a feature we always seem to talk about, WebSphere CloudBurst provides the necessary capabilities to properly allocate costs to users, teams, and organizations. To start with there are some handy usage reports that you can view directly from the WebSphere CloudBurst console. For instance, as seen below, a WebSphere CloudBurst administrator can see a break down of cloud resource usage for each user of the appliance.
While the capability illustrated above is nice, it is likely that if you are implementing an enterprise-scale chargeback scheme you want to automate the processing of the usage data, thus implying the need to programatically consume such data. WebSphere CloudBurst enables you to do just this by way of its audit log. The WebSphere CloudBurst audit log is a record of each and every action taken in the appliance, along with information about who took the action, when the action was taken, what object the action was taken on, and much more. You can instruct the appliance to generate this file for a specified date range, and the output is a comma separated value file that can then be consumed in a manner of your choosing.
As an example of some of the things you can do with this data, I recently wrote a Java program that parsed the audit file and for each virtual system determined who created it, who deleted it (if it had been removed), and the duration of its existence. This program was simple (more of a string parsing exercise than anything else), but nonetheless provided necessary function and output for billing schemes based on hours of usage. If you are interested in how this was done please let me know and I'd be happy to discuss details. In the meantime, if you have any thoughts you can reach me on Twitter via @WebSphereClouds.
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.
There have been quite a few announcements from IBM lately that keep referring to the "IBM Cloud". Since IBM has been moving at a pretty substantial pace with cloud offerings as of late, I thought it may help to give readers a concise idea of exactly what the IBM Cloud provides.
Put very simply, the IBM Cloud is a public cloud offering that allows users to provision and utilize IBM Software on an infrastructure hosted by IBM. From the IBM Cloud's web-based dashboard, users choose a software package, provide some deployment information about the particular instance they wish to create, and then simply click OK. In a matter of minutes the software is up, running, and available for full use. At the time I wrote this blog, I saw software from our Information Management, Rational, and WebSphere brands available for use. In addition, users can launch plain SUSE Linux instances out onto the IBM Cloud.
Within WebSphere, users can choose from either the WebSphere Application Server or WebSphere sMash. I just went through a WebSphere sMash deployment, and in about 6 minutes the sMash instance was up and running, and I was able to log into the App Builder development environment. The WebSphere Application Server package that's available on the IBM Cloud is particularly interesting because it contains an embedded Rational Controller Agent. This makes it very easy to integrate some of the Rational offerings on the IBM Cloud (or elsewhere) with the WebSphere Application Server. Many of these integration scenarios focus on making it easier to very quickly build, package, and deploy applications from Rational development tooling to WebSphere Application Server environments.
The best thing about the IBM Cloud is that you can sign up and give it a whirl with absolutely no costs! Go and sign up for a free account and you'll immediately be able to spin up IBM Software in IBM's cloud. You can access and use that software, and then when you are done you can simply delete the running instance. There's no need to download anything to your computer, the interface to the IBM Cloud is completely web-based, and the launched software runs on IBM infrastructure. All of this adds up to give users a super easy way to kick the tires on some of our software. Sign up now by visiting the landing page for the IBM Cloud.
One of the things I haven't written about much here is how the WebSphere CloudBurst Appliance integrates with other IBM software solutions. One of those interesting integration scenarios, and one I think is particularly useful for developers, involves Rational Build Forge.
Very simply put, Rational Build Forge is an adaptive execution framework that allows users to define completely automated workflows for just about any purpose. These workflows are represented as projects that contain a discrete number of steps. When looking at Rational Build Forge through the software assembly prism, the offering allows users to fully automate and govern the process of building, assembling, and delivering software into an application environment.
Now, on to the integration of WebSphere CloudBurst and Rational Build Forge. Users can build custom patterns in WebSphere CloudBurst that include a special script package (which I'll eventually provide a link to from here). This script package provides the glue between the deployment process in WebSphere CloudBurst and Rational Build Forge. When deploying a WebSphere CloudBurst pattern that contains this script package, users provide the name of a Rational Build Forge project as well as information about the Rational Build Forge server on which the project is defined.
Once the necessary information is supplied, the deployment process gets underway. Toward the end of the deployment, like all other scripts included in patterns, the special Rational Build Forge script is invoked. This results in the project specified during deployment being executed on the virtual machine created by WebSphere CloudBurst.
Because the Rational Build Forge project executes on a virtual machine setup by WebSphere CloudBurst, the individual steps of the project can very easily access the WebSphere Application Server environment. Thus, the Rational Build Forge project could very easily contain steps to build, package, and deploy an application into the WebSphere Application Server cell. The result is a fully automated process that includes everything from standing up the application environment to delivering applications into that environment.
I put together a short demonstration of this integration, and you can take a look at it here. As always, please let us know if you have any questions or comments. Your feedback is much appreciated!
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.
I've blogged previously about some of IBM's work in the public cloud and specifically on our partnership with Amazon to deliver IBM offerings on the Amazon EC2 cloud. Mostly on this blog I've been focused on IBM WebSphere offerings on the Amazon cloud, but coming up on October 1st, you'll get a chance to hear about and see the full breadth of IBM software offerings available on the Amazon EC2 cloud. Better than simply hearing and seeing, by attending the virtual developer's day, you'll get access to try out some of this software absolutely free!
By leveraging IBM software on Amazon EC2, users can very quickly benefit from the advantages of a cloud computing approach to IT. Instead of focusing valuable time and resource on installing, updating, and otherwise maintaining software, users can simply activate instances of the IBM software of their choosing on Amazon's infrastructure. Besides delivering this rapid approach to getting up and going, users can also leverage cloud computing techniques to quickly and dynamically scale up and down their entire application infrastructure. This ability to dynamically scale up and down means your end-users will always enjoy a satisfactory experience when accessing your applications on the cloud.
You can sign up for the Cloud Computing for Developers day here. In the meantime you can learn more about IBM offerings on the Amazon EC2 cloud by visiting the IBM/Amazon EC2 landing page. I hope you can take advantage of a chance to hear both IBM and Amazon experts and learn how IBM software delivered on the Amazon EC2 cloud can make a real difference for your business.
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.
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!
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.
IBM trekked further into the cloud today by announcing new offerings that will help clients to leverage the cloud within their enterprise. These offerings include development environments, test environments, and desktop services running either in the IBM cloud or a private cloud, as well as something called IBM CloudBurst (not to be confused with the WebSphere CloudBurst Appliance).
In particular, the IBM CloudBurst offering jumps out to me as a truly innovative offering. This offering promises our clients a complete private cloud solution that includes hardware, software, and services all in a single package.
Essentially it sounds like the IBM CloudBurst offering is all about building out a cloud-enabled data center. The hardware provides the bulk computing power to host private clouds, and the software provides enhanced service management capabilities to give users full control and insight over the elements of their private cloud.
Couple these computing capabilities with included IBM service, and this means clients should be able to get up and going with their private clouds very quickly.
This new offering really seems to hit a sweet spot. While the number of cloud computing offerings continues to grow, few if any offerings take such a holistic approach to providing such a solution.
This type of comprehensive solution gives users what they need in terms of the hardware to host a private cloud and the software to manage that cloud. Just as importantly though, it helps users put the hardware and software to work via implementation services also offered in the solution.
I invite you to take a look at the new IBM CloudBurst offering, and don’t forget to sign up for the IBM CloudBurst webcast scheduled for June 25th.
If you work in a development shop similar to mine, you and many of your coworkers have more than one workstation under your desk.We use those extra machines for a variety of reasons but by and large they they tend to serve most often as foot warmers. That is not to say that they are unnecessary but rather they simply aren't used most of the time. If you try to eliminate one, you will surely need it within the next week but if your manager asks if it is really necessary you would be hard pressed to pinpoint precisely when the last time it was used for something really important. To developers, these extra machines are potential sandboxes for isolated experiments or testing scenarios. For managers, they are relatively unused capital investments that require inventory control and have depreciating value. If you are a network administrator there are certainly computers in your inventory that are older and lack the capacity to be counted on for everyday use. They sit in a corner or in a blade rack and are probably idle or even powered off. These assets take up physical space and contribute very little to your data center. However, they have little sale value but may represent a significant investment. Or maybe you just can't part with them for sentimental reasons.
Whatever the reasons for having computing resources lying around that are seldom used, here is an idea: Virtualization. With virtualized images you can use those machines for whatever purposes are required and for as long as they are required without having to spend hours loading them with a compliant OS image, installing software and configuring them for use. Virtual image libraries could hold preinstalled systems for almost any need. It could be for anything:
Workstations provisioned for temporary workers
More server capacity
More machines or load testing
Extra processors for parallel processing systems
Back up systems to carry loads during maintenance hours
If you use WebSphere in any capacity, CloudBurst can be used to lay in place a completely functioning WebSphere install in as little as 20 minutes, OS and all.
When the need for the machine is passed, it can be un-deployed and returned to the pool. This could significantly increase the available computing power of an entire development business. The ability to turn any machine into a needed and useful system on demand is real agile computing and gives a whole new dimension to governance.
WebSphere CloudBurst delivers out-of-the-box capabilities in the form of pre-built WebSphere Application Server configurations, or patterns, which are ready to be deployed to a private cloud. These pre-built patterns range from a single server topology to more complex, clustered topologies. In addition, these patterns have been tuned to produce hardened, best-practice environments. For users, this means once they have the appliance setup, they can immediately begin building a private WebSphere cloud.
The out-of-the-box capability of WebSphere CloudBurst is extremely useful, but what about the situations where those patterns don't align with a user’s needs? What if a user needs to create a highly customized WebSphere environment? Not to worry, WebSphere CloudBurst was built with a focus on bringing customization capabilities to the user. These customization capabilities cover the full WebSphere middleware environment, from the operating system to user applications.
To start with, WebSphere CloudBurst allows users to modify the virtual images that are shipped with the appliance. These virtual images contain the operating system and WebSphere components that are used to build the WebSphere patterns. A perfect use-case for this is if a user needs to install custom software to be used in all of their WebSphere environments.
For instance, if a user wanted to install a JDBC driver that was to be used by each of their WebSphere deployments, they would simply extend one of the shipped virtual images, install the JDBC driver, and then recapture the image. Once the image was recaptured, it could be utilized to build the WebSphere patterns that represent the complete WebSphere middleware environment. By using this virtual image to build patterns, users are assured the JDBC driver will be present in each and every WebSphere deployment to their private cloud.
Another common customization is a change to the WebSphere topology in a pattern. If a user has a particular cluster environment that is different from the shipped WebSphere cluster patterns, they could simply clone the shipped cluster pattern, make any needed topology changes, and then save their new pattern.
The best thing about this process is that the topology changes are done via a slick GUI interface. Users can construct WebSphere topologies by simply dragging and dropping WebSphere components (i.e. stand-alone servers, deployment managers, web servers, etc.) onto a canvas! Once the pattern is constructed and saved, it can be reused as many times as necessary.
Patterns can also be customized to include user applications or other WebSphere configuration tuning. Script packages are compressed files (ZIP or TAR) that are constructed by users to alter the WebSphere environment. These packages might contain an application and scripts to install the application, or it could contain a script to tune or enhance the environment created by WebSphere CloudBurst.
The beauty of script packages is that they can do just about anything. Users tell WebSphere CloudBurst how to execute the script package (i.e. “Call the installApp.sh script in my script package”), and that execution takes place at the end of the pattern deployment. The result is a dispensed WebSphere environment that has been customized according to the script package contents.
There’s more to WebSphere CloudBurst customization capabilities than what I talked about above, including the ability to customize each and every deployment of a pattern, and the ability to align these customization activities with organizational responsibilities. To find out more about these capabilities, check out the demos on our YouTube channel or send us an email at email@example.com. Stay tuned to the blog for more information about the WebSphere CloudBurst Appliance.
