The single server in Pentaho 7.0 #topology

Morning

Just a quick one this on the move to a single server configuration in Pentaho 7.  This resolved a long running quirk with the Pentaho server stack, but don’t take that as a recommendation for installation in production!  It’s still very important to separate your DI and front end analytic workloads and I doubt we’ll see any other than the very smallest installations using the single server for both tasks simultaneously.

Separating the workload gives several important advantages:

  • independent scaling (reduced cost and no wasted resources)
  • security
  • protecting either side from over ambitious processing

Of course! Don’t take my word for it – Pedro said the same in the release announcement:

And luckily the Pentaho docs on the website give clear instructions for adding/removing plugins from the server – Key thing being don’t install PDD or PAZ on your DI server.

Final point – You can of course choose whether to extend the logical separation to the repository itself.  By separating the repository as well it gives you ultimate control over your system, even if for now it is hosted on the same database.
