Description

Introduction

As enterprises scale their Kubernetes infrastructure, multi-cluster OpenShift architectures have become vital to support regional workloads, high availability, disaster recovery, and compliance. This course is designed for enterprise architects seeking to design robust, secure, and scalable OpenShift multi-cluster solutions tailored to business needs. Participants will explore architecture patterns, cross-cluster communication, governance strategies, and hybrid cloud deployment approaches using OpenShift.

Prerequisites

• Strong understanding of OpenShift and Kubernetes architecture

• Familiarity with container orchestration and platform-as-a-service (PaaS) concepts

• Basic knowledge of cloud computing models (public, private, hybrid)

• Experience with OpenShift installation and operations is recommended
