This image shows an Oracle Cloud region, comprising a single Virtual Cloud Network (VCN) and spanning two availability domains (AD), labeled AD1 and AD2. The VCN also contains a single subnet, labeled "Subnet A (" that also spans the ADs. Each AD contains a web server, which are connected, indicating a failover architecture.

The VCN is connected to a dynamic routing gateway, which itself connects over FastConnect VPN to the customer's data center.
