The image shows the virtual cloud network (VCN) topology used in this architecture.
It depicts an OCI region containing a single network compartment. Within the compartment
are three fault domains. Spanning these fault domains is a VCN, subdivided into three
subnets:
- A public subnet for external facing applications and load balancers.
- A private subnet for the bastion service.
- A private subnet for shared services.
Access to the VCN is though either a Dynamic Routing Gateway, an Internet Gateway, a NAT Gateway, or a Service gateway.
