Integration Server enables you to dynamically select the connection a service uses to interact with the adapter's resource. This feature enables one service to interact with multiple, similar backend resources.

For example, you can configure an adapter service to use a default connection that interacts with your company's production application server. However, at runtime you can override the default connection and instead use another connection to interact with the company's test application server.

For more information about overriding a service's default connection at runtime, see Dynamically Changing a Service's Connection at Runtime.
