This reference architecture diagram illustrates Kubernetes in an on-premises data center and in Oracle Cloud Infrastructure, it is further described in the surrounding text.

The on-premises or 3rd party cloud has an Oracle Container Engine for Kubernetes (OKE) API Server (K8s/OKE API Server), which has a Kubernetes Cluster with User Pods, Control Plane Services & Pods, Kubernetes System Pods, Node OS Services, and Log & Object Collectors Pods. Information flows from the Log & Object Collectors Pods through the internet to Oracle Cloud Logging Analytics in a compartment in Oracle Cloud Infrastructure Region.

The Oracle Cloud Infrastructure region has a compartment and a VCN with Subnet A and Subnet B.

Oracle Cloud Logging Analytics sends information to Notifications and Alarms. Service & Audit Logs and OCI Services send information through the Service Connector to Oracle Cloud Logging Analytics.

Subnet A contains a Load Balancer. Subnet B contains a K8s/OKE API Server and OKE Node Pool with User Pods, Kubernetes System Pods, Node OS Services, and Log & Object Collectors Pods.
