We need to migrate our existing Weblogic5.1 to something better... and we have narrowed it down to three - JBoss3.2.3, Weblogic 8.1 and Websphere 5.1.
Three most important features we are looking are:
1. Good clustering and fail-over
2. Hot deploy feature
3. High performance
We're high traffic site with several daily production pushes.
I am in the process of testing these three features. I wanted to get some feedback from fellow techies who have gone thru their selection process and share some of your insights and lesson that might be helpful to me. Thanks!
