Websphere caused me only pain! A JBoss/Tomcat on Windows works 3000% faster than a WAS on a big pseries server.

Websphere is big, slow and expensive.

Do you know really advantages of using it?

I have no first hand experience with WAS, but quite a bit with BEA Weblogic as a developper. I have the same kind of greifs toward WebLo as you have against WAS : slow to start, big, expensive, ... not very developper friendly.

But when it comes to production, I have to admit that I see the value of WebLo over Tomcat. The monitoring facilities are way better, ease of deployement (especially on a cluster), much better connection pooling ...

So yes, there are reasons why you might want to choose one of the big and expensive app server.

By the way, I found WebLo slow to start, but once it has started, everything is fine. I restart my dev server quite often, but not the production servers ...

  • WebSphere tools for monitoring etc. look only nice. But when you really need them, you'll end up in frustration. – Martin K. Jul 16 '09 at 14:23

It has IBM support behind it which counts for a lot if your a large corporation. It's also written to support more platforms. If you already have a Mainframe you can run Websphere under Z/OS and leverage many of your system administrators mainframe skills to maintain it.


It has IBM standing behind it.

Don't knoch the power of that, for many people the "feel good" element of commercial support is critical for them.

  • Is IBM support the only "feature" around there? – Martin K. Jul 16 '09 at 12:55
  • Nobody ever got fired for buying IBM.

  • It takes an everything but the kitchen sink approach to things, so it gets top score on most simplistic feature list comparisons.

  • Support. Or more likely than not consulting, of course. And you'd better be running the latest version.

That said, I think Network Deployment is a rather good idea with actual added value. Not up to the price they're charging though, and it suffers from a mediocre implementation.

Think of what you'd like a multi-node app server to be able to do. Try to do that with ND - then watch it fail.
