Hi Jeff, Axis2 clustering does not work on EC2 at the moment. This is because the Group Membership Protocol (GMP) uses multicast based member discovery. However, when you start two nodes on EC2, generally, the IP is randomly assigned by Amazon from a list of available IPs, unless you use elastic IPs. Even if elastic IPs are used, you cannot request for a specific IP address, hence it is difficult to get the two IPs such that they belong to the same multicast domain. Anyway, Amazon disallows multicasting at the moment.
We are investigating whether we can use some other mechanism for group membership management.
