Answer 1

Is Amazon Elastic Compute Cloud aka Amazon EC2 an option? CentOS 5 isn't listed in the Operating Systems and Software provided by Amazon but according to this thread, CentOS 5 is very close to RHEL:

CentOS 5 is 99.9% Red Hat Enterprise Linux 5. With exception to the yum update process used within CentOS, the only difference between the two is the name. In fact, with CentOS5/RHEL5, yum is the actual update process under the hood - up2date is now just a simple wrapper around yum.

Or you could go for a shared CentOS 5 AMI provided by RightScale (check this page too).

Or maybe choose a GlassFish AMI provided by Sun (e.g. OpenSolaris + GlassFish + MySQL).

There is a solution to get a clustered GlassFish environment at low cost in the cloud and w/o the need to configure anything manually.

The following presentation provides the overview of GlassFish installation steps and how to connect your GF to MySQL database cluster.
