Being new to Tomcat infrastructure, I am wondering what an advisable setup would be to have two physical machines each running a tomcat instance to be load-balanced and capable of failover to each other? I have seen lots of posts, but to me it is still not clear what the best implementation would be.

Do I need an Apache webserver to achieve this? Or is it better to use a hardware load-balancer? etc.. How do I get the two tomcat servers to form some kind of failover? any remarks would be highly appreciated.

    Do you want to achieve performance, high availability or both?

  • The ideal situation would be both :), but our goal is also to keep things as simple as possible, this is normally the difficult when trying to achieve both high-performance and high-availability. But availability seems to be some what more important then performance.

  • How many servers do you expect use for this solution? Do you have any limitations on that?

  • 2 expect 2 tomcat servers, 2 mysql servers and 1 storage server to start with. All physical servers. It would ok if we could scale later on offcourse :)

  • Thanks nathan, so i assume that the tomcat solution is the most simple way to to achieve my goals?

  • As far as I can tell from the info you have provided. If you don't need to share sessions then you can ignore the second link.

  • So use a combination of the load-balancer with apache http is the way to go. Does the load-balancer also give me fail-over then?

  • Again, I don't know your app, but tomcat.apache.org/connectors-doc/generic_howto/… is probably more than enough from they way you have articulated it so far.
