Editor's Notes
- #3 SPServiceEvery SPService object has an Instances property that holds all the instances of the service that are running on various servers in the farm. No more than one instance of each service runs on any one server, but some services have multiple instances, each one running on a different server. Each instance is represented by an object of a class derived from SPServiceInstance.SPServiceInstanceSPServiceInstance represents an instance of a service on a server in the farm. A service instance is independent from, and identical in functionality, to all other server instances of the same type. As long as one service instance of a given service remains online, the service is fully functional. Service instances may be in the ’started’ or ’stopped’ state. A service instance provides the host process for service applications.SPServiceApplicationA service application is hosted by a service instance. Service applications are generally created by administrators. They provide the service interface, containing the administrator settings. Service applications may own user data.SPServiceProxyA SPServiceProxy is simply the parent of the SPServiceApplicationProxy. It is the equivalent of a SPService on the server side, which is the parent of a SPServiceApplication. You can also think of these parent objects as class factories for the child objects, if that makes more sense to you.SPServiceApplicationProxyService application proxies provide the public (front-end) interface to a service application. They allow client code to consume remote service applications. Service applications may not be installed locally and therefore cannot be called directly.
