Your databases run on one or more virtual machine (VM) clusters that reside on Exadata infrastructure in your data center. Exadata Cloud@Customer also includes control plane server (CPS) infrastructure that connects to an Oracle Cloud Infrastructure (OCI) region for cloud automation and administration.

Your data center connects to the OCI region to access Exadata Cloud@Customer (ExaC@C) service endpoints, Object Storage, OCI telemetry monitoring, identity service, and logging service.

You can optionally connect your data center to the OCI region with FastConnect. This option uses a public virtual circuit to connect the edge of your network to the Oracle edge in the OCI region. Your edge connects to customer-premises equipment (CPE) in your data center.

The CPE connects to a switch or router, which directs traffic to and from the CPS, network time protocol (NTP) server, domain name system (DNS) server. If you're not using FastConnect, your network should also include a proxy server (not shown in the diagram).

Your client applications and administrators connect to your VM clusters and databases over the private client and backup subnets that you access through a switch or router in your data center. You create and manage the client and backup subnets.
