The image shows a customer data center and OCI region.

The customer data center contains a production environment with two private subnets. One subnet contains the applications and middleware, while the other is a database subnet with Oracle Exadata Database Service on Cloud@Customer. The applications and middleware subnet contains Oracle Compute Cloud@Customer, web and app virtual machines, windows and linux containers, and Oracle Cloud Infrastructure Block Volumes.

The database subnet connects to storage (Oracle Zero Data Loss Recovery Appliance and a local network file system backup destination). A remote backup connects the database subnet and the service gateway in the OCI region.

Oracle Exadata Database Service on Cloud@Customer includes a Control Plane Server (CPS) infrastructure that connects to the OCI region for cloud automation and administration. The CPS is shown to connect to a switch or router, which directs traffic to and from the CPS, network time protocol (NTP) server, and domain name system (DNS) server.

The customer premises equipment (or CPE) connects to customer edge via OCI FastConnect and Oracle Edge, which connects to the dynamic routing gateway in the OCI region.

The OCI region contains an OCI Services Network where the service gateway is configured. The OCI Services Network includes the following services:
