Services are grouped together as a set of one or more services to which events can be sent. One of the services in a service group can be tagged as the source of events for all event types associated with this service group.

Each Event Routing runtime contains a default service group, which is sufficient for most use cases. However, you can also define a custom service group for a particular runtime.
