Hi Sajith, I think you are on the wrong direction. @Nirmal: Still SLB does not support hazelcast clustering.
Consider SLB as a standard load balancer which does not know anything about Carbon clustering. We just need to do a static load balancer configuration and try to simulate how WSO2 products will behave in Stratos.
