The most important question you need to answer is is your engine stateful ? Does it store any information in global, module, application level variables that a failover node will need in order to successfully process a request. Note: storing valid session ids or other information against a session or any such information within a process memory or in a storage subsystem (eg. local file system) that is not accessible to other engine classifies as stateful. Clustering stateless services is easy. Stateful ones isn't. The starting point would be to classify your system, and if feasible make it stateless. > > Regards > Uday > _______________________________________________ > BangPypers mailing list > BangPypers@python.org > https://mail.python.org/mailman/listinfo/bangpypers -- ---------------------------------------------------------------------------------------------------------------------------------- http://blog.dhananjaynene.com twitter: @dnene google plus: http://gplus.to/dhananjaynene _______________________________________________ BangPypers mailing list BangPypers@python.org https://mail.python.org/mailman/listinfo/bangpypers
