IBM expands WebSphere's framework support


By David Worthington
October 13, 2008 —  Sometimes slow and steady wins the customer. IBM has delivered the first major release of WebSphere Application Server (WAS) in four years, WAS 7. It introduces support for more development frameworks and standards, in addition to new management capabilities.

WAS 7 became generally available last week. It implements Enterprise JavaBeans 3.0, Java EE 5, the Java Persistence API, Java Development Kit 6.0 and the Spring Framework, and it broadens support for WS-* Web service specifications, said Marisa Shumway, director of WebSphere application servers at IBM. Big Blue also targeted Web service performance.

Runtime provisioning and OSGi-enabled dynamic deployment reduce startup times and resource consumption to the bare minimum set of WAS services that are required by an application. “This aligns WAS with the trend toward a pluggable architecture, which was pioneered by Iona Technologies and JBoss, and is now adopted by all major vendors,” noted Gartner analysts Yefim V. Natis and Massimo Pezzini in a September 2008 report, “IBM Adds Java EE Support in WebSphere Application Server 7.”

WAS 7 also introduces new management functions for multi-component applications, said Shumway. Other changes are designed to make controlling applications more efficient and flexible.

Cutting-edge requirements are available through optional feature packs, which introduce functionality for Web 2.0-style interfaces or Service Component Architecture. WebSphere Extended Deployment add-ons provide for more advanced capabilities including application virtualization, extreme transaction processing, high-performance computing.

Developers will be able to consume new features and technologies as they become available without having to wait for a new release of WAS through feature packs, said Shumway.

“IBM has adopted a cautious, stepwise evolution strategy for WAS. This reflects the maturity of the product and the increasingly conservative nature of its large installed base. These users are more concerned about operational efficiency and nonstop availability than breakthrough innovation or the latest standards,” Natis and Pezzini wrote.

Gartner expects that IBM will begin to realign its entire WebSphere stack (including WebSphere Portal, WebSphere Process Server and WebSphere Enterprise Service Bus) over the next 15 to 18 months, according to the report.

IBM’s Shumway said WAS 7 will run applications developed in versions of Java Enterprise Editions back to JEE 1.2.

Regardless, Gartner’s report noted that many users will have to deal with multiple versions of WAS for the next two to three years due to operational complexities, “despite the new, but unproven, WAS V7 features specifically addressing this scenario.”
