The following page has been changed by ChamikaraJayalath: http://wiki.apache.org/ws/FrontPage/Axis2/clustering_proposal New page: ====== Clustering Axis2 ====== ===== Terminology ===== HN - Head Node N1,N2,N3... - Nodes in the cluster R - repository ===== Step 1 ===== http://people.apache.org/~chamikara/images/model1.jpg **HN - ** Simply distributes incoming requests between Nodes of the cluster. Most probably based on a round-robin manner. **N1,N2... - ** Axis2 instances located in different machines. All share the same axis2.xml file and the same repository. **R - ** A remote repository, most probably situated on a separate machine. ===== Step 2 ===== http://people.apache.org/~chamikara/images/model1.jpg **HN - ** Provides basic support for session affinity. Basically an Axis2 or Synapse instance with a SessionAfinity module deployed. **N1,N2... - ** Axis2 instances located in different machines. All share the same axis2.xml file and the same repository. **R - ** A remote repository, most probably situated on a separate machine. ===== Step 3 ===== http://people.apache.org/~chamikara/images/model1.jpg **HN - ** Similar to step 1. **N1,N2... - ** Nodes share state among themselves using the ClusterManager. ClusterManager is a interface that will be introduced to Axis2 to allow replication of context state. ConfigurationContext, ServiceGroupContexts and ServiceContexts will be replicated. **R - ** A remote repository, most probably situated on a separate machine. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
