In a recent post, Joe Bohn detailed some of the new capabilities and enhancements that come along with the recently delivered IBM Workload Deployer v3.1. To be sure, there are many valuable new features such as PowerVM support for virtual application patterns, the Plugin Developer Kit, WebSphere Application Server Hypervisor Edition v8, and more. Each of these topics probably merit their own post, but today I want to talk about something I did not mention above. Specifically, I want to talk about the announcements regarding the IBM Image Construction and Composition Tool (ICCT) and what that means for IBM Workload Deployer users.
You may have read an earlier post that I wrote about the ICCT, but allow me a brief overview here. In short, the ICCT enables the construction of custom virtual images for use in IBM Workload Deployer. You use the tool to create virtual images, much like IBM Hypervisor Edition images, and then you can use those custom images (containing whatever content you need) to create your own custom virtual system patterns. The key point about the custom images you create with the ICCT is that they are dynamically configurable. That is, the tool helps you to create the images in such a way that you can defer configuration until deploy time rather than burning such configuration directly into an image. For those of you familiar with virtual image creation, you know this type of 'intelligent construction' is a huge step towards keeping image inventory at a reasonable level.
Okay, enough of a general overview for now. Let's talk about the two new items of note regarding IBM Workload Deployer v3.1 and the ICCT. The first thing you should know is that starting in IBM Workload Deployer v3.1, the ICCT is shipped with the appliance. This means that you do not need to go anywhere else in order to get your hands on the tool to start creating your custom images. You simply log into IBM Workload Deployer and click the download link on the appliance's welcome panel (shown in image below).
Getting your hands on the tool is one piece of the puzzle, but using it is quite another. While the ICCT has been available as an alphaWorks project for some time, that also implies that there has never been official support for the tool. That changes starting with IBM Workload Deployer v3.1. The ICCT is now a generally available product from IBM, and that means that it is fully and officially supported as well. Further, the images you create using the tool are also officially supported for use as building blocks of your IBM Workload Deployer virtual system patterns. For many of you who have been using the ICCT for some time, but have been hesitant to expand use because of the lack of a formal support statement, you should now feel free to charge forward!
I hope this helps clear up exactly what the new Image Construction and Composition Tool announcements that were part of IBM Workload Deployer v3.1 actually mean. I cannot wait to hear about how you all are putting the ICCT to use with IBM Workload Deployer. Finally, don't forget to send us any questions, comments, or other feedback that you may have regarding this or any other new feature in IBM Workload Deployer v3.1!
Jason McGee will be leading the second GWC Lab Chat this week on Wednesday, 4/20. The very timely topic is related to recent announcements from IBM regarding the IBM Workload Deployer (see previous posts). Entitled "Application-Centric Cloud Computing" the discussion will focus on the concept of deploying and managing your application workloads in a shared, self-managed environment rather than manually creating and managing the application middleware topologies. It places the focus on the application rather than the infrastructure. This concept promises to deliver greater simplicity, elasticity, and
density among other things. It can position your business to react more
quickly and efficiently to the increasing demands of your customers and
free you from the managing all of the details.
Many of you may have already heard Jason speak last week at IMPACT 2011 in the cloud mini main tent or perhaps at any number of other sessions that Jason was involved in. Jason is the key architect behind IBM's WebSphere cloud activities. Obviously, Jason understands the cloud space very well and has a clear view of the evolution into Application-Centric Cloud Computing. This GWC Lab Chat will provide the opportunity to get your questions answered and share your perspective on this technology.
Jason will provide a brief introduction to the concepts and ideas and then lead an open discussion. Put it on your calendar and plan to attend - and please plan to bring your questions and comments to help foster a rich discussion. We want to hear from you.
If you haven't registered yet it is not too late - learn more and register here. It is easy to register and there is no cost. This is a very timely event and a great way to dig a little more deeply into concepts you first heard at IMPACT or perhaps hear them for the first time. Don't miss it!
IBM Workload Deployer v3.1 firmware has been released and is available for download. V3.1 includes many improvements, building upon the solid foundation that was laid in V3.0 and earlier releases of WCA. There are many improvements and enhanced features. Dustin already alluded to a few of these in his previous post but let me list again here some of the more prominent new features:
The ground breaking capabilities offered in our Virtual Application Patterns have been extended to include deployments for AIX on PowerVM - giving you more choices for your private cloud environment. Along with this support a new base operating system image for AIX is also available for extension using either extend and capture or the IBM Image Construction and Composition Tool. Of course, Virtual System Patterns continue to be supported on all three private cloud hypervisors we support: VMWare, PowerVM, and zVM.
A new version of the Web Application Pattern Type (formerly WebApp Pattern Type) has been released. The Web Application Pattern Type V2.0 is built upon the feature rich WebSphere Application Server V8.0 release.
The DBaaS Pattern Type has been updated and is now the IBM Database Patterns 1.1 which includes both the IBM Data Mart Pattern 1.1 and the IBM Transactional Database Pattern 1.1 (OLTP - the default). These pattern types support a broader range of offerings for both production and non-production use. You can choose to create a new type of workload standard to apply to the DB instance or you can choose to clone an existing DB image that has been backed up to your DB image catalog repository.
A number of improvements have been made to the shared services leveraged by Virtual Application patterns. The caching service used to persist session data when scaling a web application can itself now be configured to scale, adjusting to increased demand. We have also extended the shared services to support external caching services and to leverage an external monitoring service based upon Tivoli Enterprise Monitoring Server (TEMS). You can also deploy multiple instances of shared services by deploying to multiple cloud groups.
The Plugin Developer Kit that was previously released to support building your own plugins and pattern types for Virtual Application patterns is now available for download directly from the IBM Workload Deployer dashboard - making it even easier to gain access and experience using this extension mechanism to deliver your own custom plugins and pattern types.
Images created using the IBM Image Construction and Composition Tool are now fully supported in IBM Workload Deployer V3.1 Virtual System patterns. Furthermore, the IBM Image Construction and Composition Tool is now a generally available product that is fully supported and available for download directly from the IBM Workload Deployer dashboard.
Speaking of Virtual System Patterns - a new hypervisor edition image of WebSphere Application Server V8 is now delivered with the appliance. WebSphere Application Server V8 fully supports the JavaEE6 programming model and includes many other programming models directly in the base image that were previously delivered only as feature packs including OSGi, JPA, and many more.
One item already mentioned by Dustin is the ability to configure multiple IBM Workload Deployer appliances in a master/slave relationship with a floating IP address to support continuous availability in the event that the master become unavailable. This feature can also be leveraged to support continuous operation while performing maintenance.
Another key appliance improvement is increased appliance security through the introduction of several new security roles for separation of duties. This is to ensure that no single user has unrestricted control without oversight. Among the new roles is an auditing role and auditing operations to provide data for forensic analysis of security attacks and better assist with compliance with the Health Insurance Portability and Accountability Act (HIPAA) and the Sarbanes Oxley Act (SOX).
We believe that these new features and several more make the value proposition delivered by IBM Workload Deployer V3.1 an even more compelling offering that can increase agility, consistency, and time to value for your applications. You can download IBM Workload Deployer V3.1 from IBM Fix Central. Please let us know what you think!
Sorry for the late notice - but I just realized that I hadn't blogged about a webcast that I am participating in tomorrow (Tuesday, 9/13)!
Chris Brealey (a Senior Technical Staff Member and Rational Enterprise Architect) and I are hosting an InformationWeek WebCast tomorrow (Tuesday, 9/13) entitled "Quickly and Efficiently Design, Develop, Deploy, and Test Workload Application Patterns to Save Months and Millions". I encourage you to register now for this free event (or if you can't make it tomorrow listen to it at your convenience as it will be recorded ... but you still need to register).
I'm really looking forward to this webcast. IBM Workload Deployer's predecessor, WebSphere Cloudburst Appliance, delivered unmatched capabilities for middleware deployments and management using Virtual System patterns (topology) - delivering complete middleware topologies in a rapid, consistent, and repeatable fashion. This has greatly improved the ability of development and test organizations to meet the ever increasing demands of today's agile development processes in addition to the assurance it provides for production environments. All of that value is still present (and improved) in IBM Workload Deployer but there is even more value in the new Virtual Application Patterns, as we've mentioned in previous posts.
Virtual Applications build upon this same notion of consistency and speed found in Virtual Systems while at the same time introducing a radical simplification to hosting your applications. Using an application-centric, declarative approach with Virtual Applications (workloads) it is even easier to deliver your applications rapidly leaving Workload Deployer to ensure the middleware environment is constructed and optimized to meet your application criteria. Virtual Applications usher IBM Workload Deployer into the realm of Platform-as-a-Service ... with even greater simplicity and agility to host your application in the most efficient fashion. As with Virtual System patterns earlier, we expect the introduction of Virtual Applications to continue to improve the dev/test lifecycle as well as production. The robust capabilities of Rational Application Developer and the simplicity of Virtual Application patterns in Workload Deployer make for a great combination.
I will start off the webcast with a discussion of PaaS and IBM Workload Deployer Virtual Application patterns. Chris will then discuss the application development process and how that is influenced with the introduction of the cloud environment. Chris will then explore the integration that is available in Rational Application Developer for IBM Workload Deployer. Finally, we will walk through a scenario that demonstrates how to leverage Virtual Application patterns in IBM Workload Deployer to design a solution that is then shared with the developer. Using Rational Application Developer the developer delivers the application into the pattern and moves it to test and finally pre-production. We will end with a question and answer time. I hope you can join us as we explore how we can use these technologies to increase agility and efficiency.
The answer is yes, I did a related but different blog post with a similar title a few weeks back. At that time I was primarily highlighting a webinar that I co-presented with Keith Smith regarding the various virtualization solutions and features that are available in IBM Workload Deployer in virtual application patterns and virtual system patterns leveraging the Intelligent Management Pack (IMP). If you didn't get a chance to attend that webcast live then I encourage you to check out the replay (especially Keith's portion with details on IMP - a really helpful overview).
This new blog post expands on the theme of that original blog post but takes a broader vision of where IBM has been with our private cloud offerings in WCA and IWD up to and including the recently announced IBM PureApplication System - and how this history demonstrates our leadership in supporting applications in the cloud.
As Joe mentioned in his last post, virtual application patterns are all the rage in IBM Workload Deployer. The high degree of abstraction provided by these patterns means users can remove tedious, time consuming tasks like middleware installation, configuration, and integration from their field of view. As a consequence, users can build and deploy application environments in unprecedented time, thus freeing up more time to focus on the actual application.
This is obviously important because building and deploying application environments are crucial, traditionally time consuming activities. However, what happens after you build and deploy the application? You manage it, that's what! Joe brought up the fact that IBM Workload Deployer makes this easier too by delivering an integrated management portal through which you can manage and monitor your application environments. Now, this probably already sounds valuable, but what really puts it over the top is the management portal exposes an interface that is workload aware. But, what does that mean?
To get an idea of what that means, consider the case that you use the shipped virtual application pattern to build a simple application environment with a web application and database. You deploy it with IBM Workload Deployer, and your application is up and ready. Now you want to start checking things out. You start by opening the management portal directly from the appliance, and you see both the application and database components listed in the view:
After you looked at basic machine statistics such as network activity and memory usage, you could move on to a more workload-centric view. For instance, you could examine statistics particular to a web application such as request counts and service response times:
You may also decide that you want to alter certain aspects of your deployed environment. As an example, you could update your deployed application or change certain configuration data in the deployed environment:
It is important to note that you have a management interface for each of the components in your environment. That means that from the same management interface, you can manage and monitor the database you deployed as part of your environment. For example, at different intervals, you may want to backup your database. You can do this directly from the management portal provided by IBM Workload Deployer:
Lest you think that you can only manage and monitor, this unique management interface is also a one stop shop for all of your troubleshooting needs. From the centralized portal, you can view log and trace data for each component:
Virtual application patterns are an attempt to encapsulate each phase of your application's lifecycle, from creation to deployment to management. In this regard, I hope the above provides a taste of some of the management capabilities provided by virtual application patterns. It truly is the tip of the iceberg!
A few weeks ago, I had a conversation with a current WebSphere customer about the potential value they could derive from the use of IBM Workload Deployer. Right away, this customer saw value in the consistency that a patterns-based approach could afford them. It was clear that patterns eliminate the uncertainty that can make its way into even the best-planned deployment processes. Initially though, the customer questioned the value of being able to do fast deployments because, in their words, "We don't deploy WebSphere environments that often." So, we continued our discussion, and then they asked an important question that I encourage all of our users to ask: "Why don't we deploy our WebSphere environments more frequently?"
It is interesting to talk with our WebSphere users that have a long history with our products. Often times, they have been taking a shared approach to WebSphere installations for many, many years. They develop innovative approaches and isolation schemes that allow them to carve up a single WebSphere installation (cell) amongst multiple different application teams. This allows them to avoid having to setup a cell for each application deployment and saves them the associated time. However, having talked to many different users taking this approach, it is not without its challenges.
As was the case in the customer I mention above, users typically made trade-offs when electing for larger, shared cells. As an example, if you have multiple different application teams with different types of applications using a single cell, applying fixes and upgrades to that cell can be a lot more complex. After all, you now have to coordinate plans across a number of different teams and find a window that fits all of their needs. For the same reason, trying incremental function via our feature packs is much more arduous in these types of cells. Additionally, administrative controls become more complex since teams with varying needs all require administrative access. Admittedly, this gets simpler with newer fine-grained security models in WebSphere Application Server v7 and v8, but it still requires organizational discipline and process.
At this point I should be clear that I am not denigrating the shared cell approach. It can work well, and we have many facilities built into the WebSphere Application Server product to support that model. However, if you are using this approach and you find yourself stumbling too much for your own liking, then I would strongly suggest that you explore the patterns-based approach of IBM Workload Deployer. By deploying patterns that represent your WebSphere cells using IBM Workload Deployer, you can quickly and consistently setup multiple WebSphere Application Server cells to support the varying needs of your application teams. You will still avoid spending an inordinate amount of time installing and configuring cells as that is an automated part of pattern deployment, and your application teams will still get the resources they need. Further, this can liberate your application teams in terms of how they apply maintenance, install upgrades, and absorb new function in the form of feature packs.
I am not suggesting a complete pendulum swing in your approach to how you manage multiple application environments. There is definitely a happy medium in terms of how many cells you end up with. After all, you do not want to trade in one set of problems for the problem of managing way too many different cells. However, I do think that decomposing monolithic, multi-purpose cells into smaller, more purposeful cells can be beneficial. In the course of thinking about this different approach, you may come to the same conclusion that the customer I mention above did. IBM Workload Deployer's rapid deployment capabilities are indeed valuable if you take a slightly different view of current processes.
I just wanted to point out a great opportunity for anybody considering leveraging IBM Workload Deployer v3 to deploy Database workloads. On June 29th Rav Ahuja, a Senior Product Manager for Data Management at IBM, will be hosting a webcast entitled "Easily Deploying Private Clouds for Database Workloads". He will be joined by Chris Gruber (Product Manager, Database as a Service), Leon Katsnelson (Program Director, IM Cloud Computing Center of Competence), and Sal Vella (Vice President, Database Development and Warehousing) in this panel discussion.
As many of you already know, IBM Workload Deployer v3 comes pre-loaded with DB2 images and patterns that are configured to rapidly provision standardized database servers for any number of purposes. The servers can be deployed in standalone configurations or as part of a complete virtual system including web components with the database components. These servers can also be configured for high availability scenarios. This panel discussion will cover all of these scenarios and more.
You can read more about the webcast in this blog post by Rav Ahuja.
If you want further details about how to build and rapidly deploy databases in a private cloud, be sure to attend this free webinar on June 29th.
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.
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!
The soon to be released IBM Workload Deployer is already being integrated with many IBM products. One of these is the Rational Application Developer. I created a short video demonstration of a simple scenario that includes multiple phases of an application from development to production using IBM Workload Deployer. The scenario starts with the Solutions Architect creating a workload application pattern for a stock trading application. It then moves to the developer working in Rational Application Developer and demonstrates this integration that allows the developer to access the workload pattern, publish the application that she has built in Rational Application Developer into the pattern, and then deploy the pattern to the test cloud. All of this without leaving the Rational Application Developer user interface. The scenario then continues with the test team adding policies and validating the application before the deployment manager finally makes some final adjustments and adds places the application into the production cloud.
