puppet for deployment of Java apps

[Bhuwan]

Hello,

Is Puppet a good choice to deploy JAVA applications (Tomcat) where there exists a cross-system dependency (i.e. the database should be deployed before the web app)?

If not, any suggestions for alternatives?

I can only recommend a push based solution(puppet is a pull based). I
like python so I use fabric[1] but I know that other shops(ruby based) use
capistrano.

If the DB will be the only precondition it might be ok to do this with
puppet but for something more distributed a push based solution is far
better.

We use Puppet to deploy multi-tiered apps.

Our apps are packaged as RPMs using the Maven RPM plugin (generally, we use RPM to express dependencies, such as Tomcat/Apache).  For orchestration (setting up the DB before starting the app,for example) we use MCollective (calling the different tiers by specifying facts that tell MCollective which nodes to run at which point in the process)

We are also actively moving towards not needing the orchestration - making the apps resilient enough to embrace failure (i.e. of the DB is not available, wait a while and try again)

You seem to emphasize Java, but I don't see what that has to do with anything.

Puppet does not (currently) provide for orchestration, so it cannot by itself ensure that your Tomcat server is configured only after your DB on a different node has been.  That might or might not present an actual problem for you.

As I know linkedin is using glu for automatically deployment and glu already open-sourced, do you know is there some unify approach to deploy java applications(war, ear) to some standard server like tomcat, jboss, websphere. (Cargo maybe is one for support the most server with limitation)
