In a post not long ago, I mentioned new enhancements to virtual system patterns in IBM Workload Deployer. A prominent part of those enhancements were updates to pattern construction that allow you to order virtual machine startup, order script package invocation, and include add-ons that provide system level configuration options. Recently I uploaded a demonstration to YouTube that highlights some of these new capabilities. Specifically, this provides a brief look at ordering and add-on enhancements.
I hope you take a look, and even more importantly, I hope to see some feedback. If you have something you would like to see captured in a demo, let me know and I'll work it to the top of a long and continually growing list!
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 recently read the Open Cloud Standards incubator charter proposed by the Distributed Management Task Force (DMTF), and I think this is a great effort to propel the cloud computing effort forward (read the charter here). In the interest of disclosure, I’m not just saying this because I happen to be employed by one of the supporters of the movement. It’s time to acknowledge that open standards are not an inhibitor to innovation, but instead they facilitate the kind of technological adoption that makes innovation both possible and profitable.
The incubator charter sets its eyes on standards around cloud resource management. Its main focus will concern the management of cloud computing elements that make up the Infrastructure as a Service (IaaS) layer, but it will also discuss some elements of the Platform as a Service (PaaS) layer. The charter lists among its deliverables a cloud taxonomy, cloud interoperability white paper, informational specifications, and security requirements for cloud resource management. The hope is that such standards would increase cloud interoperability, mitigate the potential for vendor lock-in, and guide companies who already deliver resource management products and are looking to extend such capabilities to cloud resource management.
In particular, there are a couple of deliverables that sound interesting. The first, a cloud taxonomy including terms and definitions, is a necessary step to move forward any cloud computing standardization efforts. There is too much disagreement among the cloud industry at large as to exactly what defines and makes up cloud computing. While healthy discussion and debate on this subject are good, it is time to agree on a standard definition that all can at least accept. Without a common, acceptable definition, standards movements will be crippled since it’s hard to govern something we cannot define.
The charter also proposes information specifications that would define profiles for the management of resources within a cloud computing environment. If these types of management standards were produced and subsequently adopted by a multitude of cloud providers, consumers could define a common cloud interaction layer and freely switch in and out the provider. In addition to these new specifications, updates to existing standards in DMTF are among the deliverables. The existing specification that is explicitly called out in the charter is the OVF packaging standard. I can only hope this means a standard packaging for virtual images deployed in a cloud environment. If that is indeed the goal, by combining a common cloud management mechanism with a common cloud packaging strategy, consumers would be provided the ultimate choice among cloud providers. They could package and deploy services meant to run in the cloud in such a way that the task would be repeatable across any cloud provider adopting the DMTF’s standards. In addition, the mention of updating existing specifications sends a clear message that cloud computing standardization efforts must not duplicate existing standards work. Instead, new specifications are introduced where necessary, and existing specifications are updated to accommodate this new computing paradigm.
I’m excited about the incubator charter announced by DMTF. I’m sure this is just the beginning in what will be a long journey of providing for an open cloud, but it is a necessary first step. I for one don’t buy the argument that open standards stifle innovation. Instead, I believe open standards increase technological adoption, and more consumers mean more opportunities, and demand, to distinguish offerings by creative innovation. What do you think about cloud computing standards? Let us know below, or send us an email.
More and more, I am getting a question about how to bring existing WebSphere environments into IBM Workload Deployer. While "bringing in an environment" can mean any number of things, let's take it to mean that a user wants to import their existing WebSphere cells, applications, and configuration into IBM Workload Deployer as a pattern they can subsequently deploy. While there may not be a big red easy button in the appliance that lets you point to an existing environment and import it, there are a couple of techniques that one can employ. I have covered both techniques before, but since I'm getting the question with increasing frequency, I felt like it was time for recap.
The first option is to use a combination of IBM Workload Deployer and Rational Automation Framework for WebSphere. This is a use case I have spoken about numerous times at conferences and in blog posts and articles. In fact, you can read a little about it here. In this sense, RAFW provides excellent capabilities to point at an existing cell, and import everything about it. This includes WebSphere configuration, applications, shared libraries, and more. Once imported as a RAFW project, you can use the IBM Workload Deployer integration script package provided by RAFW to replay that configuration on top of deployments created by the appliance.
The second option is something I talk about a little less frequently. This option revolves around the use of a sample script (provided for free in our samples gallery) that you can run against existing WebSphere cells. The invocation of this script produces IBM Workload Deployer script packages that you can use in patterns to apply the configuration of the target cell to your new cloud-based deployments. Under the covers the utility script and resultant script packages use backupConfig and restoreConfig respectively. They do ensure the update of the cell, node, and host names during the restoreConfig execution (which happens automatically during pattern deployment). Beyond that, the use of the script is subject to the same limitations and rules in place for the use of the backupConfig and restoreConfig commands. You can read more about this capability, watch it in action, and download it for free.
I hope this is all useful information for those of you looking for ways to import existing environments into IBM Workload Deployer as patterns. If you have any questions, please let me know!
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.
It isn't often that the IT world looks at the federal government as technological pioneers, and the new CIO of the Office of Management & Budget, Vivek Kundra, thinks that is a problem. Kundra is striving the for the federal government to become key leaders in innovation, and in doing so, he's looking at cloud computing as a first step.
Due to the sensitivity and privacy of data the government is often handling, one may not think cloud computing the best fit. Kundra, however, does not see that as a show stopper. "We recognize that whether it's cloud computing or any area of technology there is sensitive and classified information and it cannot be treated the same way as public information, but they are not mutually exclusive." While only a few words, Kundra makes it clear that one of the biggest perceived fears of adopting cloud computing, security and privacy, will not stand in the way of the federal government's march to innovation.
It's still early in his tenure, but the First CIO seems to be serious about his push for cloud computing. He says that he is "killing projects that don't investigate software as a service first", and he is keen on looking to the cloud for storage and web development solutions. Kundra also believes that by leveraging cloud solutions across the multitude of federal agencies, we can ensure that resources are used only when needed by replacing the always-on data center with outsourced solutions where possible. He's also counting on the adoption of cloud computing to send a strong message that government agencies can lead technological innovation.
I doubt anyone would discount the benefits Kundra is seeking by attempting to move the federal government in the clouds. He hopes to reduce tax dollar spending by using only the necessary IT resources, improve end-user services for tax payers, and foster a culture of technological innovation among a myriad of federal agencies. There is no doubt that such a transition and culture change will not come easy, but Kundra sounds dedicated to an honest effort at change. If the federal government is able to effectively leverage cloud computing solutions, I believe it could be a trend-setter for many organizations. If an entity as unwieldy and complex as the federal government can adopt and derive benefits from cloud computing, I believe many organizations that once discounted the technology may take a fresh look at the capabilities at hand.[Read More]
We've been talking a lot about IBM Workload Deployer V3 and we will continue to highlight different aspects of the capabilities it provides in the coming weeks. As we've already mentioned - IBM® Workload Deployer V3 is not just another release of the IBM WebSphere CloudBurst Appliance. While it builds on WebSphere CloudBurst's success, and supports and improves upon all of its original capabilities, Workload Deployer provides new application-centric computing capabilities for your private cloud, and brings you higher utilization, improved ease of use, and more rapid application deployment.
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!
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.
