Hi,
I'm using Amazon EC2 instance (windows) to run Glassfish V3 (I'm going to update to 3.1 soon).
I need to run the same application with multiple databases for each client on one machine.
My question is which configuration is better:
1. Domain for each client - this looks like the safe side, each client get it's own configuration, database, connection-pool, etc.
2. Application deployment for each client on one domain - this may take less resources but one client can take down the whole site.

Also what kind of computer (CPU, memory) should I use for running 10 domains on one glassfish installation?

Thank you,
Ido.
