JBoss: HTTP load-balancing

The Sterling Order Management System Software HTTP screens are stateful in the sense that a screen preserves state information for subsequent screens.

As a result, you have to set up proxy servers or load-balancers to load-balance HTTP requests with a “sticky” load-balancing policy. This ensures HTTP requests go back to the server that have the session states.

Load-balancing can improve performance for large number of HTTP users because the user population is serviced by multiple application servers that are managed as a cluster. Load-balancing can be implemented with a variety of technologies ranging from the Apache proxy servers to hardware-based load balancers.

HTTP session replication

Please refer to JBoss Enterprise Application Platform for details to set up HTTP Session replication. Testing was performed with mod_jk and mod_cluster module with sticky session enabled.
