The image shows an Oracle Cloud Infrastructure region, which is in a Siebel environment, and an on-premises implementation.
The OCI region comprises three availability domains (ADs), Availability Domain 1, Availability Domain 2, and Availability Domain 3. These ADs are within a virtual cloud network (VCN), which extends into the region. The VCN contains three subnets, one allocated as public/private, and the other two allocated as private subnets. Access to each subnet is managed by a routing table and a security list.
The public/private subnet contains a Siebel Cloud instance in AD 1, a Gitlab instance in AD 2, and an OCI load balancer in AD 3.
- The node in AD 1 contains Siebel Application Interface 1, Siebel Cloud Gateway 1, and Siebel Server 1, each containing a server and a pod.
- The node in AD 2 contains a Helm/Flux cluster, along with Siebel Cloud Gateway 2, and Siebel Server 2. Each Siebel component contains a server and a pod.
- The node in AD 3 contains an Nginx Ingress Controller, along with Siebel Application Interface 2, and Siebel Cloud Gateway 3.
The third private subnet contains a Primary Siebel Database in AD 1 and a Standby Siebel Database in AD 2. They are synchronized by Data Guard.

Traffic between the OCI region and the on-premises implementation is from a DRG on the VCN and customer premises equipment over VPN/FastConnect.
