Single-region IBM Cloud for Financial Services reference architecture for VPC with Red Hat OpenShift on IBM Cloud
If you want to use containers, you can add Red Hat OpenShift on IBM Cloud to your VPC. Except for the addition of Red Hat OpenShift on IBM Cloud, you use the same architectural patterns and components that were described for the Single-region IBM Cloud for Financial Services reference architecture for VPC with Virtual Servers for VPC.
The following diagram shows a more detailed view of both the management and workload VPCs when Red Hat OpenShift on IBM Cloud is introduced.
Architecture diagram
You can choose to use Red Hat OpenShift on IBM Cloud alongside (or instead of) virtual servers in either or both VPCs. Even though it is shown in the diagram as an option, it is not required to put Red Hat OpenShift on IBM Cloud in your management VPC.
Red Hat OpenShift on IBM Cloud concepts
Red Hat OpenShift on IBM Cloud is a managed offering to create your own Red Hat OpenShift on IBM Cloud cluster of compute hosts to deploy and manage containerized apps on IBM Cloud. Red Hat OpenShift on IBM Cloud provides intelligent scheduling, self-healing, horizontal scaling, service discovery and load balancing, automated rollouts and rollbacks, and secret and configuration management for your apps. Combined with an intuitive user experience, built-in security and isolation, and advanced tools to secure, manage, and monitor your cluster workloads, you can rapidly deliver highly available and secure containerized apps in the public cloud.
Red Hat OpenShift on IBM Cloud extends the Kubernetes platform with built-in software to enhance app lifecycle development, operations, and security. The master nodes are entirely IBM's responsibility, while there is shared responsibility for the worker nodes.
For IBM Cloud for Financial Services, you should provision Red Hat OpenShift on IBM Cloud only in a VPC and not in classic infrastructure.
