An Environment Instance, as its name suggests, is simply an association between one environment and one instance. An Environment Instance is created by either associating an instance to an environment on the edit/create environment wizard, or associating an environment to an instance on the edit/create instance wizard. The association can then be used to assign endpoints and provide values for any properties mapped to those environment instances (through workflows or plugins).

PROD | Endpoint (s) | Endpoint (s) |

The properties are linked to the environment instance because either one or more of the workflows or plugin operations associated to the instance have Environment Instance scoped properties defined. These Environment Instance scoped properties must have values defined for every Environment to which that instance is mapped. This provides, for example, the ability to define unique Weblogic Admin Server host and port for each environment instance.
