Load Balancers
Clustering in Mediator requires a load balancer. The load balancer is a third-party tool that routes incoming virtual service calls from CentraSite to the nodes in the cluster. For Mediator, the load balancer:
Provides
CentraSite with a single point of entry to the cluster. This means that
CentraSite recognizes only that it is communicating with a single entity rather than multiple nodes. All communication from
CentraSite to the cluster goes through the load balancer.
CentraSite deploys virtual services to the load balancer, and whichever node is prepared to take action processes the message.
Distributes calls from service consumers to the virtual services across the cluster. When a service consumer calls a virtual service, the call is routed by the load balancer to the node prepared to process the call.
