RPC Plumbing Diagram
This section outlines the moving parts required to invoke a service. Each
service has a small family of helper interfaces and classes. Some of
these classes, such as the service proxy, are automatically generated
behind the scenes and you generally will never realize they exist. The
pattern for helper classes is identical for every service that you
implement, so it is a good idea to spend a few moments to familiarize
yourself with the terminology and purpose of each layer in server call
processing. If you are familiar with traditional remote procedure call
(RPC) mechanisms, you will recognize most of this terminology already.
