Afkham Azeez commented on SYNAPSE-360:
--------------------------------------
I have made changes to the Axis2 clustering implementation that allows a node
to behave as a load balancer. The changes were made to the axis2 clustering
module and the one class(ClusterBuilder) in the deployment package in the axis2
kernel and in the clustering package in the axis2 kernel.
All test cases pass with Axis2 SNAPSHOT though

> There are some limitations in the current load balancer implementation. e.g.
> if we have 2 identical services in 2 different worker nodes, which are
> fronted by a synapse load balancer instance. In such a case, we need to
> provide 4 endpoints in the synapse.xml file. As can be seen, this is not a
> very scalable solution. Hence, I have implemented an dynamic load balancing
> mechanism where the application members are discovered at runtime, and the
> endpoint do not need to be statically specified in the synapse.xml file.
> Currently, the application endpoints are calculated by replacing the IP and
> port of the incoming request with that of the member to which this request
> will be forwarded to. I have only tested with HTTP/S for the moment. More
> details about the concept & design can be found here:
