A connectivity group represents a specific pattern of behavior found in an SCA module.
Create connectivity groups to represent the possible request sources for the system.

These connectivity groups provide encapsulation and isolation of the specific endpoint's integration requirements. Commonly, WebSphere® ESB mediation modules are used for this purpose as they represent convenient ways implement "infrastructure" related tasks.
When the system is recovered and able to process new work, these modules can be restarted.
The module that is outlined in the following screen capture is considered part of a connectivity group.
Connectivity groups can be used for input from an external source or an existing system such as SAP or CICS®. Or for new work from a web browser-based clients.
