This document describes the reference architecture for the Red Hat OpenShift Container Platform 4.12 solution based on the Lenovo ThinkSystem, ThinkEdge, and ThinkAgile HX platform. The document provides a technical overview of Red Hat OpenShift Container Platform, which is built around a core of application containers powered by CRI-O, with orchestration and management provided by Kubernetes, on a foundation of Red Hat Enterprise Linux (RHEL) or Red Hat Enterprise Linux CoreOS (RHCOS). Lenovo ThinkSystem DM series can be used as persistent storage with storage provisioner supporting Container Storage Interface (CSI). The document also provides Red Hat OpenShift Container Platform deployment overview on bare-metal and hyper-converged infrastructure.
Red Hat OpenShift Container Platform provides many enterprise-ready features like enhanced security, multi-tenancy, virtualization, simplified application deployment, and continuous integration/continuous deployment tools. With Lenovo servers and Lenovo Open Cloud-Automation (LOC-A) technologies, deployment, provisioning and managing the Red Hat OpenShift Container Platform infrastructure becomes effortless and produces a resilient solution.
The document also describes how Red Hat OpenShift extends the capabilities of native Kubernetes to edge side, supporting a flexible edge site configuration, from single node to 3 nodes, from regional location to far edge, let organization select mixed and matched topology at their edge sites.
Lenovo works closely with Red Hat to provide a series of engineered, tested, and certified OpenShift Deployment Ready Solutions (DRS) for customers to get fast time to value benefit and accelerate business advantage.
The reference architecture is intended for IT decision makers, infrastructure and application architects looking to plan and implement On-Prem and Edge container cloud. Knowledge of containers, Kubernetes, cloud, and data center infrastructure architecture will be helpful.
