IBM's WebSphere: Dances With Mainframes

IBM's WebSphere Application Server has the most appeal for those who already have a good deal of Blue in their blood.


IBM's WebSphere Application Server has the most appeal for those who already have a good deal of Blue in their blood.

In late 2000, Atlanta-based National Account Service Co. (NASCO), which processes more than 100 million health-benefits claims yearly, was looking for a Web application server to give customers the ability to check their claims online. That data is still hosted on IBM mainframes. So while BEA's WebLogic had better support for Java standards at the time, "WebSphere offered us more features integrated with an IBM environment," says Mark Badia, NASCO's chief technology officer. For example, he says, WebSphere supports mainframe file structures and works well with IBM's MQ message-queuing middleware.

IBM loves to tout WebSphere's ability to run on multiple hardware systems, including mainframes, but the company has had trouble maintaining consistency across them at times. Aurora Health Care, a health-care provider based in Milwaukee, runs WebSphere on AIX and z/OS for mainframes but its developers work on Windows and Linux machines. Frustratingly, WebSphere code developed on one platform behaved differently on another, according to Duane Wesenberg, director of Web applications development at Aurora Health. "We were always having problems when we promoted an application up to the big iron," Wesenberg says. IBM has fixed the problem in recent releases, he says.

WebSphere is also mind-numbingly complicated, some customers say. "If you're not integrating an application to a back-end system, I wouldn't look at WebSphere," says Todd Stewart, director of information technology for Brenntag North America, a subsidiary of a German chemical distributor. "I'm willing to tackle the complexity because of the benefits we get from the platform."

But others argue that WebSphere is no more difficult to get your arms around than BEA's WebLogic. "The level of complexity for either platform is quite close," says Roman Lys, an information-technology manager with Toronto-based Scotiabank, which runs its online banking applications on WebSphere. The most important issue for companies embarking on Java development, he says, is building expertise in-house.
