The task of deploying a software stack as a VM image onto a virtualized server has historically been a highly labor-intensive task. For instance, one has to first deploy and configure the OS along with all requisite patches. After that, the administrator has to install and configure the application server and all its constituent components (e.g. HTTP server, etc.) as well as patches and other fixes. For applications requiring a database, that becomes yet another piece of middleware that needs to be installed and configured. Then there is the application itself. Collectively, deploying and testing a complete application manually can require days or weeks to accomplish depending upon its overall complexity. In a private cloud environment, this kind of turnaround is untenable. The IBM Workload Deployer is specifically designed to address this problem. To the right is a screenshot of the pattern designer for IWD.
Following the IBM lead, Oracle is now starting to move in a similar direction. In June 2010 Oracle announced the Oracle Virtual Assembly Builder. This product provides provisioning of the virtual appliances into the Oracle VM environment. Other than overall lack of product maturity, there are number of significant limitations with the current version of the Oracle Virtual Assembly Builder product. Read full comparison in this blog entry: Comparison of two private cloud tools from IBM and Oracle.
When Oracle ships new version of the OVAB product, I will update my comparison, but for now this is the best I can do given current versions of both products.

Following Oracle’s acquisition of Sun it was determined, to no one’s surprise, that the Java CAPS middleware suite was not a strategic middleware platform and would be eventually moved to a “sustain” mode for support (in the interim support costs are likely to rise). What this means to Java CAPS customers is that they would see little or no new investment in the platform. This raises questions of what they should do about new IT projects (e.g., do you continue to invest development effort in an effectively defunct SOA infrastructure?) as well as the value of the subscription and support dollars currently being spent on the Java CAPS platform.
Oracle would of course prefer to see these customers move to SOA Suite, but despite many promises to deliver migration tooling has done little to bridge the gap from Java CAPS (and especially e-Gate). Java CAPS customers are essentially left with the choice to throw out their code investments by starting over with a new platform, which brings with it a host of new challenges (new skills to develop, business risk and potential interruptions, etc.).
What many Java CAPS clients are now discovering is that IBM not only offers a robust SOA platform alternative, but they have now delivered a migration toolset that is capable of preserving their investments in Java CAPS Collaboration and ETD/OTD assets by parsing and recreating that same code into the WebSphere target environment. Combine this toolkit with other assets such as WebSphere Support Pac IAM6, and you can see that IBM is willing to make investments to help customers running Java CAPS where Oracle has not.
With new version 8 capabilities, industry specific accelerators, and WebSphere Message Broker’s new packaging options that provide low cost entry points with the same reliability and robust scalability, it is not surprising that more Java CAPS customers are stepping back to consider their options.

If you have been reading this blog you must have noticed that so far most of the discussion was around Oracle and IBM. You might be wondering how would WebSphere compare to JBoss? Good question indeed. I am not going to cover this topic in its entirety in this one post as it would be impossible anyway, but I would like to review posts published earlier and provide a quick summary on JBoss status as it relates to the topics covered:
I hope this was useful for those of you who are JBoss curious.

Managing application servers manually may work on a small scale. With increasing number of servers and number of applications it takes more and more effort to keep the systems up and running. In this article I am comparing IBM and Oracle approach to solve this problem.

In this article last week I have compared WebLogic and WebSphere support for the latest JEE6 standard (which WebLogic does not yet support). However I am often asked if there any other standards and APIs that are different between these two application servers. One might look at the market share reports where WAS and WLS are within a few percentage points of each other and assume that there are no big differences between these two products.

Today I posted a detailed article on SmarterQuestions blog comparing the performance of WebSphere Application Server and Oracle WebLogic Server: Which is faster – WebSphere or WebLogic?.

I just posted a new blog on the smarterquestions.org about the JEE support in WebSphere and WebLogic: http://smarterquestions.org/2011/11/application-infrastructure-how-about-jee6-support/.
In general I will be posting in both of these blogs – and making some cross posts. Hope it works well for everyone.

IBM has collected a number of facts about potential savings that customers could experiences if they switch from Oracle Fusion Middleware to IBM WebSphere. This mini-website has a collection of documents on this subject.
Parallel to this theme – here is another interesting site with the wealth of info and free services for Oracle customers to help them reduce their license and support costs. This site is from an independent IT consulting company and is not sponsored by IBM.
