A service binding provides seamless communication over a private overlay network within your identity domain between Oracle Application Container Cloud Service and another Oracle Cloud service. Also a service binding coordinates to the bound service using environment variables.
A service binding is not necessary to connect to an Oracle Public Cloud service that provides a publicly accessible endpoint (such as Oracle Database Exadata Express Cloud Service) or a REST API (such as Oracle Cloud Infrastructure Object Storage Classic or Oracle Messaging Cloud Service).
In Oracle Application Container Cloud Service, you can add service bindings to other subscribed Oracle Cloud services from the Deployments page of the Application Console or configure them using the
deployment.json file. To learn more about how to define service bindings in the
deployment.json file, see Creating Metadata Files.
