Red Hat OpenShift architecture on AWS
At a high level, the Red Hat OpenShift infrastructure runs on AWS, and the cluster is registered on the Red Hat Portal. When you create a cluster, you provide your Red Hat account details. This generates a token that helps identify your Red Hat account. The following diagram illustrates the high-level process, regardless of the implementation method you choose:
-
Create a Red Hat account.
-
Generate a token from the account.
-
Use the token to provision a cluster on AWS.
-
Administer the cluster by using the Red Hat console.
The entire infrastructure, including the control plane, user nodes, and Network Load Balancer, runs on AWS.
Infrastructure requirements
Because Red Hat OpenShift uses Kubernetes for container orchestration, it requires infrastructure components such as a virtual private cloud (VPC), subnets, and Amazon Route 53 on AWS. These requirements can change depending on the topology, but the following core components are always required:
Kubernetes and Red Hat OpenShift Container Platform control plane services that run on master nodes
The default router
The container image registry
The cluster metrics collection or monitoring service
Cluster-aggregated logging
Service brokers
