The clustering regulates high scalability and availability. The basic considerations for servlet clustering are:
1. Objects opened in a session could be serializable to support in-memory replication of sessions. Also consider the problem of serializing very big objects. Test the performance to make sure it is running.
2. Design for idempotence. Failure of an impatient or a request users clicking again may result in duplicate requests being given. So the Servlets could be relay to tolerate duplicate requests.
