In my SF application a stateful Worker service communicates with a stateless Logging service using service remoting. The stateful Worker service creates the Logging proxy in its constructor using ServiceProxy.Create<ILoggingService>(loggingServiceUri) and keeps the returned reference for its entire lifetime. There are several stateless Logging service instances running on the cluster (i. e. Instance Count == -1). My question is:
Are calls to the ILoggingService proxy form the Worker service routed to different Logging service instances?
Yes, when you are using SF remoting to talk to a stateless service, your message will be delivered to a random instance. The proxy will keep track of healthy instances for you, and deal with transient errors.
