Shared Services

A Shared Service is a Service instance that multiple Clients executing on different processes or machines can attach to. State is maintained across the Service instance, and there is only one instance at any given time of a particular Shared Service running on a Broker. For example, you might use a Shared Service when GridServer Service invocation requests are delivered on an Enterprise Service Bus to a middle-tier client. If this middle-tier client is load-balanced across multiple systems, using a Shared Service lets the Broker reaggregate these related Service invocations.
