One of the key benefits of WebSphere CloudBurst adoption is rapid -- seriously fast -- deployments of middleware application environments. Our users are leveraging the appliance to bring up enterprise-class middleware environments in mere minutes. If you know a little bit about WebSphere CloudBurst, that statistic may be a little surprising considering the appliance dispenses large virtual images from the appliance over the network to a farm of hypervisors. You may ask how the appliance can achieve such rapid deployments in light of the mere physics involved in transferring large amounts of data over a network. The simple answer is caching of course!
WebSphere CloudBurst creates a cache for each unique virtual image on datastores associated with the hypervisors in your cloud. On subsequent deployments of the same virtual image to the same datastore, WebSphere CloudBurst does not need to transfer the image over the wire. It simply uses the virtual disks that are in the cache on the datastore. In the context of the virtual image cache, the deployment process goes something like this:
WebSphere CloudBurst identifies the images necessary to deploy the pattern selected by the user.
WebSphere CloudBurst identifies the hypervisors and associated datastores that will host the virtual machines created during deployment.
WebSphere CloudBurst checks the selected datastores to see if they already have caches for the images it will be deploying. From here, one of two things happens:
WebSphere CloudBurst detects that there is no cache on the datastore and transfers the images over to the hypervisor, thereby creating the cache on the underlying datastore.
WebSphere CloudBurst detects that there is a cache on the selected datastore and uses that cache in lieu of transferring the disk over the wire.
The process may sound complicated, but it is completely hidden from you, the user. You do not need to know how the cache works since WebSphere CloudBurst handles all of these interactions. So, why am I telling you all of this then? As a WebSphere CloudBurst user, it is good to be aware of the cache for two main reasons. First, you need to account for the storage space the cache needs when doing capacity planning for your WebSphere CloudBurst cloud. Second, anytime you upload or create a new image through extend and capture, I would strongly suggest you automatically prime the cache for this new image. You can do this by simply deploying a pattern built on the image to each unique hypervisor/datastore in your environment. This may take a temporary re-arrangement of cloud groups, but it is a simple process, and it guarantees rapid deployments for all users of the new image.
I hope this sheds a little light on a subject we do not discuss too often. As always, if you have any questions, do not hesitate to let me know!
I hardly ever have a conversation about WebSphere CloudBurst, or generally cloud computing for application middleware, without the topic of databases coming up. Databases are such an important piece of nearly every application middleware environment, so users want to be sure that whatever they do for their application servers, they can also do for the databases on which their applications rely. That is why the capability to deploy DB2 from WebSphere CloudBurst has been around for as nearly as long as the capability to deploy WebSphere Application Server.
Even though DB2 deployment capability has been around for a while, there are still some common misconceptions regarding the offering. First, I have talked to a fair number of users who are under the impression that we only offer a trial version of DB2 for deployment via WebSphere CloudBurst. While that was true for the first few months of the offering, that is no longer the case. For several months now, a fully supported, 64 bit, production-ready DB2 image has been ready for use in WebSphere CloudBurst. If you were waiting for a DB2 image that you could go live with, wait no longer!
The other misconception, or rather, point of confusion, arises from the fact that the DB2 image for WebSphere CloudBurst is not, by name, a Hypervisor Edition image. I can assure you that is in name only. The DB2 image looks like and behaves like any other IBM Hypervisor Edition image once you load it into the appliance. You can use it to build and deploy patterns in the same way you use other images in WebSphere CloudBurst. You may just have trouble finding it if you search for 'DB2 Hypervisor Edition' as opposed to 'DB2 Server for WebSphere CloudBurst Appliance.'
Instead of going into further detail, I want to refer you to a blog entry from a fellow IBMer, Leon Katsnelson. Leon is a program director for DB2 and is responsible for the team that develops and delivers the DB2 image for WebSphere CloudBurst. In his most recent post, he provides a nice overview of the image and gives good information for those looking to use DB2 and WebSphere CloudBurst (there is also a bit on cloud computing at the beginning that I think is spot on). Check out Leon's post, and let us know what you think!
In last week's post, I put the spotlight on various aspects of bundles in the Image Construction and Composition Tool. I finished with a look at a WebSphere CloudBurst virtual image created from the bundle. However, you do not just magically go from a bundle to an image that you can use in WebSphere CloudBurst, Tivoli Provisioning Manager, or on the IBM Cloud. Today, I want to show you how to go from a bundle to a custom virtual image using the IBM Image Construction and Composition Tool.
Once you have defined at least one bundle and one base operating system image, you are ready to compose a custom image. We already talked about creating a bundle, but the base operating system image is a new topic. You can do this by either starting from ISO and kickstart configuration files, or you can import an existing Open Virtual Appliance (OVA) image that contains your operating system of choice. Once you have that base image imported or defined in the Image Construction and Composition Tool, you can extend it to create a custom image on top of the base OS image.
After creating your extended image, you can add bundles that represent the software you want to install in your custom image. Simply click on the Software tab of the new virtual image. Click the add icon, and select the bundle that you want to add. You can add as many bundles as you would like to your custom image.
After adding a bundle, it will show up in the Planned list of software for the image. Click on it to display its details in the right side of the screen. You will notice General, Install, and Configuration sections for the bundle. In the Install section, you will find a list of the installation parameters you defined for the bundle. You can provide values for the parameters at this time.
If you click on the Configure section, you will see all of the configuration paramters you specified for the bundle. You can provide default values, and you can specify whether or not these should be configurable by deployers of your custom image. If you mark them as configurable, users will be able to provide values for the parameters at image deploy time, regardless of whether they provision the image using WebSphere CloudBurst, Tivoli Provisioning Manager, or the IBM Cloud.
After you add the necessary bundles and specify installation and configuration data, you can save the image. Upon saving, the image status changes from Synchronized to Out of Sync.
Now you are ready to synchronize the image. To do this, simply click the synchronize icon. This will result in the creation of a virtual machine in the cloud envrionment (VMware or IBM Cloud) you defined in the selected cloud provider. The Image Construction and Composition Tool will then invoke the appropriate installation tasks (per the bundles you included in the image) within the running virtual machine. It will also copy over any configuration scripts you defined in the bundle.
After a while, the synchronization process completes, and the image returns to the Synchronized state. At this point, you are ready to capture the image by clicking the capture icon. This results in the creation of an OVA virtual image with your customizations. When the capture process completes, the image status changes to Deployable.
Once the image is in the deployable state, it is nearly ready to use. If you are using the IBM Cloud as your cloud provider, you can simply mark the image complete by clicking the complete icon. At this point, the image will show up in your private catalog on the IBM Cloud and it is ready to use. If you are using VMware as the cloud provider, you need to export the image. Click the export icon and provide information about an SCP-enabled server to which you want to export the image. Ideally, this location is directly reachable by the WebSphere CloudBurst or Tivoli Provisioning Manager environment into which you will import the image.
You can monitor the export status in a separate window by clicking on a link shown after clicking the OK button in the dialog above. When the export finishes, you are ready to import your new custom virtual image into WebSphere CloudBurst or Tivoli Provisioning Manager.
I hope the last three posts have given you a better idea of what the new IBM Image Construction and Composition Tool is all about. There will definitely be more to come about this tool in the near future, but in the meantime, if you have any questions or comments, please reach out to me. Until then, good luck and full speed ahead on your custom image compositions!
In previous posts, I have discussed the integration capability between WebSphere CloudBurst and Tivoli Service Automation Manager. Most recently, I discussed this in the context of integrating WebSphere and IBM CloudBurst. Today, I am happy to announce the publication of an article I co-wrote with Marcin Malawski from TSAM development on the subject of this integration.
If you are a WebSphere user interested in a holistic approach in building out a private cloud, I strongly recommend that you check the article out. If you are currently an IBM CloudBurst, IBM Service Delivery Manager, or Tivoli Service Automation Manager user and you provision a significant number of WebSphere environments, I strongly recommend that you check the article out. In fact, regardless of your current situation, do me a favor and check the article out!
As always, I look forward to feedback and comments. Good, bad, or indifferent. You can leave your comments here or on the article page. I look forward to hearing from you!
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!
One of my favorite books from childhood is If You Give a Mouse a Cookie. Although targeted at children, the book illustrates a frequently occurring human behavior that is important for all of us understand. That behavior is the tendency for escalating expectations. The book offers this up by starting out with the simple action of giving a mouse a cookie. The mouse in turn asks for a glass of milk, various flavors of cookies, and on and on, until the mouse circles back to asking for another cookie.
Nearly all of us exhibit this same kind of behavior, and it can often produce positive results. In particular, in IT we always push for the next best thing or a slightly better outcome. Personally, I am no stranger to this behavior because I experience it from WebSphere CloudBurst users quite frequently. In these cases, it usually revolves around one particular outcome: speed of deployment.
Bar none, users of WebSphere CloudBurst are experiencing unprecedented deployment times for the environments they dispense through the appliance. The fact that we say you can deploy meaningful enterprise application environments in a matter of minutes is far beyond just marketing literature. Our users prove it everyday. However, just because they are deploying things faster than ever does not mean they are content to rest on those achievements. They want to push the envelope, and I love it.
For our users looking to achieve even speedier deployment times, I offer up one reminder and one tip. First, analyze all of your script packages to ensure you are using the right means of customization. If you have some scripts that run for considerably longer than most other script packages, you may want to at least consider applying that customization by creating a custom image. You still need to adhere to the customization principles outlined here, but you may benefit from applying the customization in an image once and avoiding the penalty for applying it during every deployment. You may also be able to break this customization out with a combination of a custom image and script packages. For instance, instead of having a script that installs and configures monitoring agents, you may install the agents in a custom image and configure them during deployment. Being selective about how and when you apply customizations can go a long way in improving your deployment times.
In addition to the reminder above, I also have a tip. Take a look at all of the script packages you use in pattern deployments and look to see if there are any that you can apply in an asynchronous manner. In other words, identify customizations that need to start, but not necessarily complete as part of the deployment process. Going back to our example of configuring monitoring agents during the deployment process, it may be important to kick off the configuration script during deployment, but is it crucial to wait on the results? Maybe not. If it is not, consider defining the executable argument in your script package in a manner that kicks off the execution and proceeds -- i.e. nohup executable command &. This approach can save deployment time in certain situations.
My advice to users of WebSphere CloudBurst: keep pushing your deployment process! Pare as many minutes off the process as you can. I hope that the tips above help in that regard, and be sure to pass along other techniques that you have found helpful.
Maybe you remember, but not long ago I wrote a post about scenarios when WebSphere CloudBurst and Rational Automation Framework for WebSphere (RAFW) combine to form quite the pair. You can read that post for details, but the basic scenarios were configuring and capturing, importing existing environments into WebSphere CloudBurst, and migrating from virtual to physical installations. Well, after talking with customers and colleagues lately, you can add another scenario to the list: version-to-version WebSphere Application Server migrations.
I want to be clear here about one thing before I go further. I am in no way advocating against the use of the migration tooling that ships with WebSphere Application Server. It is an excellent tool that can make migrations simple and fast. I am merely pointing out that when it comes to version-to-version migrations you have options, and you should survey them all before making a decision.
With that understanding, let's take a look at WebSphere CloudBurst and RAFW in the context of a version-to-version migration. This integrated approach to migration is ideal if you are amenable to moving up to a newer version of WebSphere Application Server in a cloud-based environment. Using both products makes migrations fast and easy, and you can be very confident that the configuration of the migrated environment is faithful to the original. The figure below shows the basic flow of the migration and breaks it down into a set of discrete steps.
Now, for a quick break down of each step:
Extract config & apps from old environment: The first step involves pointing RAFW at your existing configuration, the one you want to migrate from, and using an out-of-the-box action to import all of the configuration into a RAFW environment. You can also import your application binaries in this step.
Store config & apps from old environment: In step two, you will store the extracted configuration and application binaries in a source control repository or some backup location separate from your RAFW server. This is an optional, but recommended step.
Analyze and update apps: Before migrating your applications to the newer version of WebSphere Application Server, you can use the completely free Application Migration Toolkit to analyze the source code of your applications. This toolkit will recommend any required updates to ensure your application continues to behave as expected when moving to the new version. Again, this is an optional step, but the toolkit is free and very handy. So, why not?
Deploy new version of the environment: Step four starts by building a new WebSphere CloudBurst pattern. This new pattern matches the topology of the environment you are migrating from, and you build it from an image containing the version of WebSphere Application Server to which you want to migrate. Once built, you deploy it to your private cloud and you have a running environment in minutes.
Apply stored config and deploy updated apps: Now that you have your new environment up and running, use RAFW to apply the configuration you extracted from your old environment. RAFW inherently understands any configuration translation that needs to occur to apply the old configuration to your new environment, and it can also deploy your updated applications for you.
That's the basic overview for version-to-version migrations when you are moving to a cloud-based environment. In time, I will be posting more information about this process to shed a little more light about what is going on under the covers. In the meantime, you know how to reach me if you have questions!
One of my favorite things to do with users or potential users of WebSphere CloudBurst is to help them understand how they can construct a custom environment using the appliance. Typically, we take one of their existing application environments and discuss the configuration steps that contribute to its makeup. From there, we map the required configuration actions to different customization capabilities in the appliance. It is one thing to talk about how you can customize every layer of your application stack with WebSphere CloudBurst, it is quite another to talk about it in the context of an existing environment. This exercise usually serves to greatly enhance a user's understanding of how to construct tailored environments with the appliance.
While I cannot take every one of you through this exercise in the context of one of your own application environments, I can propose a scenario that will help to illustrate the WebSphere CloudBurst customization process. Consider that I want to deploy a clustered WebSphere Application Server environment whose application server instances utilize WebSphere DataPower XC10 for HTTP session management. In order to deploy such an environment, I would need to do the following:
Install an OS and WAS
Install the WebSphere eXtreme Scale Client binaries - required for integration
Construct a clustered cell
Augment profiles with WebSphere eXtreme Scale profile templates
Configure the application server instances to use WebSphere DataPower XC10 for session management
So those are the steps, but how do they map to WebSphere CloudBurst? First, I know that the WebSphere Application Server Hypervisor Edition image used by WebSphere CloudBurst encapsulates the installation of the OS and WAS. I also know that WebSphere CloudBurst will automatically construct the clustered cell during the deployment process. That means I need to address the installation of client binaries, augmentation of profiles, and configuration of application server instances. In order to do this, I will use a combination of image extension and custom script packages.
To get started, I extend an existing WebSphere Application Server Hypervisor Edition image and simply install the WebSphere eXtreme Scale Client binaries. I then capture that image and store it as my own unique image in the WebSphere CloudBurst catalog. Now, you may wonder why I did not capture the profile augmentation in the custom image. Remember, you cannot change profile configuration during the extend and capture process as WebSphere CloudBurst resets the profiles as part of capturing the custom image.
My custom image encapsulates the installation of the client binaries, so now I turn to custom script packages. I need two in this case. One script package will augment a profile (either deployment manager or custom node) with the WebSphere eXtreme Scale profile template. The second script package will configure application server instances to use WebSphere DataPower XC10 for HTTP session management. Once done with these script packages, I have all the assets I need to build my target environment.
Using my custom image, I build a pattern that contains the number and kind of WebSphere Application Server nodes that I want. I use the advanced options to define a WebSphere Application Server cluster ensuring its creation happens during deployment. Next, I drag and drop the profile augmentation script onto the deployment manager and custom node parts in my pattern. Finally, I drag and drop the WebSphere DataPower XC10 configuration script onto the deployment manager. The pattern is now ready to deploy!
For those of you that are visual learners like me, this demonstration provides a nice overview of exactly what I wrote about above. Check it out and let me know what you think.
The majority of my posts on this blog address using various features of WebSphere CloudBurst to build private cloud computing environments. Today though, I want to switch gears and instead of talking private cloud, let's talk public cloud. Specifically, let's take a look at the capabilities and services delivered via the IBM Smart Business Development and Test on the IBM Cloud (hereafter referred to as the IBM Cloud).
For some of you, the fact that IBM has a public cloud offering may be a little surprising. After all, if you listen to some uninformed critics you may hear that IBM only cares about private clouds for large enterprises. That is simply untrue. The IBM Cloud is an Infrastructure as a Service public cloud that delivers rapid access to services hosted on IBM infrastructure via a self-service web portal. The IBM Cloud offers multiple payment options, including usage-based billing and reserved capacity billing, and even features a cost estimator so you can confidently establish a monthly budget for your usage.
Regardless of whether you use a private or a public cloud, security should always be a chief concern. As such, IBM takes security very seriously in the IBM Public Cloud. The infrastructure that constitutes the cloud is subject to internal IBM security policies that include regular security scans and tight administrative governance. Your data and virtual machines stay in the data center to which you provisioned them, and physical security policies match those of internal IBM data centers. Additionally, you can optionally make use of the virtual private network option to isolate access to the virtual machines that you provision on the IBM Cloud. Rest assured that security in the IBM Cloud was a guiding design principle and not an afterthought.
With the basics out of the way, let's get on to the question I'm sure you have: What can I run on the IBM Cloud? To get you started, the IBM Cloud provides a nice list of public images in its catalog that are ready for you to provision. These images include WebSphere Application Server, WebSphere sMash, DB2, WebSphere Portal Server, IBM Cognos Business Intelligence, Tivoli Monitoring, Rational Build Forge, and many more. In addition to the public images provided by the IBM Cloud, you can build your own private images. Private images allow you to start with a base public image and then customize it by adjusting the configuration or installing new software. Once customized, you can store these private images on the IBM Cloud and provision them whenever needed. Whether you are using public or private images, you have a number of server configurations to choose from in order to host your environments.
While very brief, I hope this overview provides you with some of the more important details regarding the IBM Cloud. There are few, if any, service providers out there with the enterprise expertise of IBM, and I think you see that reflected in the IBM Cloud. If you are looking at public cloud options for your enterprise application environments, you should definitely take a closer look at the IBM Cloud.
I spent most of my time growing up doing two things, going to school and playing sports. I made many fond memories -- mostly from the latter :) -- and learned more than a few lessons over that time. Of all of those lessons, there was one in particular that stuck out in both the classroom and on the baseball diamond: Sometimes you have to get back to the basics.
In that vein, I think it is time to revisit the basics of WebSphere CloudBurst. In revisiting the basics, I am not talking about the technical basics of the appliance. Rather, I am talking about revisiting exactly why WebSphere CloudBurst exists in the first place. In other words, let's take a look at the problem domains WebSphere CloudBurst addresses, and let's discuss a little bit about how the appliance does so.
A couple of weeks ago, I wrote about a sample I was working on that would allow one to apply a layer of governance to their WebSphere CloudBurst patterns. Earlier this morning, I posted the sample to the WebSphere CloudBurst Samples Gallery under the 'Sample CLI Scripts for WebSphere CloudBurst' section. The name of the new sample is 'Check WebSphere CloudBurst patterns', and you can download it here.
As hinted in my earlier post, the new sample is a simple way to check your patterns against assertions you supply in a properties file. It allows you to check that patterns contain the correct parts and scripts, and it allows you to verify that they were built from valid images. The assertion format is pretty basic, but it should be flexible enough to allow you to check patterns against a wide array of requirements. The sample archive includes a readme file that explains exactly how to use the script, and it contains a sample assertions file to give you an idea of the input syntax.
I hope this helps to address some of the requirements of many WebSphere CloudBurst users that told me they were in need of a way to apply governance to their patterns. If you have any questions about the sample, please let me know. Alternatively, if you have another idea or a problem you would like to see addressed by a sample in our gallery, please let me know.
In the course of my job, I am lucky to be able to work with both enterprise users and business partners who are adopting and using the WebSphere CloudBurst Appliance. When it comes to the business partner camp, one of my absolute favorites is the Haddon Hill Group. The Haddon Hill Group is an IBM Premier Business Partner, and they have been an early adopter and vocal advocate of the WebSphere CloudBurst Appliance. They have extensive knowledge of the use of the appliance in enterprise accounts, and quite frankly, they are doing some really cool things with WebSphere CloudBurst.
Given the above, I was glad to see summarized results from their various implementations made available recently on the IBM site. The summary is fairly concise, so I encourage you to take a look at the results Haddon Hill Group is getting with WebSphere CloudBurst.
I am not going to rehash the contents of the results here, but there are a couple of things I want to call out. First off, Haddon Hill Group says that WebSphere CloudBurst can provide companies with a '100 times faster time to market' delivery experience. In a practical sense, this means reducing the amount of time to deliver WebSphere environments from 40-60 days on average to just hours. That is an eye-opening data point!
The other thing I want call out here is a quote from Phil Schaadt, President and CTO, Haddon Hill Group. I have had the pleasure of working with Phil and team, and I have heard him echo these same sentiments many times:
"The important thing about the IBM WebSphere CloudBurst Appliance is that it will dispense a WebSphere Application Server image onto your WebSphere Application Server environment or private cloud along with other products within the WebSphere stack, and that application server will be ready in a few minutes. You can do it in a clustered environment, and you can even roll out IBM WebSphere Process Server and get it right in a fully clustered environment with a database connection, in about 90 minutes. You can also easily manage all the configurations of IBM WebSphere Process Server that you need. All the steps that took up so much time and effort on the part of IT staff have been removed. The savings for companies with large WebSphere implementations can be in the millions."
It is always great to see clients putting our technology to use to produce tangible business value. Again, I encourage you to take a look at these reports. As always, I am eager to hear what you think, so leave me a comment or reach out to me on Twitter @damrhein.
I spend most of my time talking with our users about the WebSphere CloudBurst Appliance. While I believe the appliance is somewhat of a hybrid among the Infrastructure as a Service and Platform as a Service layers of the cloud, it is definitely closer to IaaS than PaaS. Users recognize that, and they can identify the capabilities of WebSphere CloudBurst that correlate with IaaS cloud functionality.
That said, I often get questions regarding IBM and work in the PaaS arena. These include questions like, 'Is IBM planning to do anything with PaaS?', 'What is your take on PaaS?', 'What kind of applications do you plan on targeting with your PaaS offering?', and more.
Well, rest assured that IBM is definitely embracing the PaaS movement. Instead of trying to answer these questions in this post though, I want to make you aware of a recent InfoQ interview with IBM WebSphere CTO, Jerry Cuomo. In the interview, Jerry answers the questions above and much more. Jerry talks about IBM's plans for PaaS, what such a platform might look like, and how he sees IBM competing against some of the cloud players in this space.
The interview runs about a half hour, but there is a very nice table of contents that allows you to navigate to specific question/answer segments with Jerry. If you are interested in PaaS, and specifically in IBM's intention in this space, I encourage you to take a look at the interview. Let me know what you think!
One of my favorite things to do is create content that you, our users, can directly use to adopt and implement our products. Luckily for me, my job allows me to spend a considerable time doing just that for our WebSphere CloudBurst Appliance. In the course of this kind of work, I use multiple different mediums to hand over what I hope is helpful content to you. This includes blogs, articles, demos, and the WebSphere CloudBurst Samples Gallery.
While I like creating content for all of these forums, if I had to pick a favorite, I'm going to go with the samples gallery every time. The reason for this is simple. Users can download and directly use the content in the samples gallery. The samples gallery plays host to script packages, CLI scripts, and other tools that are ready to use with WebSphere CloudBurst (of course, one can also extend these or simply use them as reference). Further, the samples in the gallery are mostly direct responses to suggestions or requests I get from users regarding this type of content, thus increasing its usefulness and relevance.
A good example of the kinds of assets in the gallery is the latest script package I put out there. Recently, I was talking to a user and asked, 'What do you do every single time you establish a WebSphere Application Server environment?' He outlined a few different tasks, one of those being the creation of virtual hosts in the server's configuration. The creation of virtual hosts piqued my interest because many users do that, and the configuration logic itself is fairly consistent regardless of the administrator doing the task. Therefore, I set about creating a sample script package that you can use to create virtual host configuration in WebSphere Application Server.
The script package does two things. It creates virtual host entries, and it configures host aliases for these entries. The script allows the user to supply the data for the entries and aliases they want to create via a properties file. The properties file is pretty basic and allows for the configuration of multiple host aliases for each virtual host entry. Here is an example properties file:
The script package parses the data from a properties file like the one above, and it creates the appropriate WebSphere Application Server configuration. If you are using WebSphere CloudBurst and this kind of configuration task is common for your deployments, you may want to download this free sample. I also want to point out that there are quite a few more samples that are completely free for you to download in the gallery. Check them out and let me know what you would like to see in the samples gallery!
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 184.108.40.206, 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 220.127.116.11 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 18.104.22.168 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.
