Preparing the environment to split processing between IBM App Connect Enterprise and IBM App Connect Enterprise as a Service

When you split message flow processing between IBM® App Connect Enterprise and IBM App Connect Enterprise as a Service, you must configure a connectivity agent.

Before you begin

These instructions assume that you installed App Connect Enterprise on premises, and that you provisioned an instance of App Connect Enterprise as a Service.

About this task

When you split processing between App Connect Enterprise and App Connect Enterprise as a Service, your flows communicate by using a Switch server and connectivity agent. The Switch server, which routes data, is managed for you by App Connect Enterprise as a Service. The connectivity agent contains the certificates that your flows require to communicate securely with the Switch server. A connectivity agent must be running in the App Connect Enterprise integration server where you deployed your on-premises message flows.
The diagram shows an application in Integration Bus, and an application in App Connect Enterprise on IBM Cloud.  The CallableFlowInvoke node in a flow in application 1 in Integration Bus uses a Switch server in the cloud to call the CallableInput node of a flow in application 2 in App Connect Enterprise on IBM Cloud.
The diagram shows an application in App Connect Enterprise on Cloud, and an application in IBM Integration Bus.  The CallableFlowInvoke node in a flow in application 1 in the cloud uses a Switch server in the cloud to call the CallableInput node of a flow in application 2 in Integration Bus.

The Switch server is already created in App Connect Enterprise as a Service. You must download an agent configuration file from the cloud, and use it to configure the on-premises connectivity agent. Your callable flows use this agent to communicate with each other securely, through the Switch server.

To prepare the environment to split processing between App Connect Enterprise and App Connect Enterprise as a Service, configure a private network connection in App Connect Designer. For more information, see Connecting to a private network in the App Connect Enterprise as a Service documentation.
