A service exposes GIS resources like maps, rasters, locators, geodatabases, and so forth through REST and SOAP interfaces. The type of the service is often dictated by the type of resource being published. In addition to accessing the underlying resource, a GIS service can expose additional capabilities called extensions (or server object extensions). Extensions are packages of custom functionality that can perform business logic or expose the service through additional formats or protocols.

When a service is started, it is ready to service requests from users. A service typically has one or more instances (objects) defined by the minInstancesPerNode and maxInstancesPerNode parameters in the service definition. The maxIdleTime parameter defines how long these objects are kept alive when not in use.

The status resource on the service describes the current state of the service. To get detailed information about the instances in your service, you can access the statistics resource.
