Once you determine what you are going to do, please report back. It
will be interesting to hear what you decided.
One choice is to do the following:
- one domain with a DAS
- create a node for each physical system and each VM
- create a stand-alone instance for each application (45 instances)
- deploy the applications to the instances.
This allows you to manage the entire setup from a single admin console
and all applications are isolated in their own JVMs.
If some applications can run together in a shared JVM, then the number
of instances can be reduced.
If some applications need more than one instance for scalability or
reliability, then clusters can be created.
With this setup, the DAS will not have any trouble managing this many
instances.
