Using the In-Process Service
The In-Process (IP) service is a pre-defined service that enables different parts of an application runtime to exchange digital events without using an external messaging server. Only one In-Process service exists per runtime.
You cannot modify the configuration of the pre-defined In-Process service or create a custom In-Process service. You can only add the In-Process service to a service group. In the service group, you can set the Usage property for the In-Process service only to Source and Destination.
For more information about how to configure a custom service group, see
Configuring Custom Service Groups.
