Technical Overview

Red Hat OpenShift is an enterprise Kubernetes platform that extends upstream Kubernetes with essential tools and services tailored for streamlined container orchestration, security, and consistency. It efficiently manages containerized applications across hybrid cloud, public cloud, and on-premises VMware infrastructure.

Underpinning this platform is Kubernetes, an open-source container orchestration system. Red Hat OpenShift Container Platform builds on Kubernetes by adding developer-centric tools, integrated CI/CD pipelines, and enterprise-grade security. For enterprises utilizing VMware environments, OpenShift Virtualization enables running traditional VM workloads alongside containers, ensuring a seamless hybrid infrastructure.

VMware complements OpenShift with solutions like VMware vSphere and VMware Cloud Foundation, providing enterprise-grade compute virtualization and cloud infrastructure layers. VMware NSX facilitates network virtualization, securing microservices traffic within OpenShift clusters. VMware vSAN enhances storage by delivering distributed storage that integrates closely with container storage interface (CSI) drivers for persistent OpenShift volumes.
