Overview of this book

For IT professionals working with Red Hat OpenShift Container Platform, the key to maximizing efficiency is understanding the powerful and resilient options to maintain the software development platform with minimal effort. OpenShift Multi-Cluster Management Handbook is a deep dive into the technology, containing knowledge essential for anyone who wants to work with OpenShift. This book starts by covering the architectural concepts and definitions necessary for deploying OpenShift clusters. It then takes you through designing Red Hat OpenShift for hybrid and multi-cloud infrastructure, showing you different approaches for multiple environments (from on-premises to cloud providers). As you advance, you’ll learn container security strategies to protect pipelines, data, and infrastructure on each layer. You’ll also discover tips for critical decision making once you understand the importance of designing a comprehensive project considering all aspects of an architecture that will allow the solution to scale as your application requires. By the end of this OpenShift book, you’ll know how to design a comprehensive Red Hat OpenShift cluster architecture, deploy it, and effectively manage your enterprise-grade clusters and other critical components using tools in OpenShift Plus.

OpenShift Multi-Cluster GitOps and Management

In the first chapter of this book, we discussed the main challenges most organizations face in scaling their Kubernetes infrastructure in a multi- or hybrid-cloud world. New challenges arise when you deploy multiple clusters on different providers, such as the following:

  • Inconsistent security policies: Clusters with different configurations regarding access rules and user profiles, allowed/blocked network flows, certificates, and other security aspects make an organization more vulnerable to data breaches and other security events.
  • High operational effort to manage all clusters: Managing configurations, components, compliance, and policies for several clusters is overwhelming.
  • Deploying and managing applications: The deployment process becomes much more complicated when you need to do it over several clusters. Monitoring and managing them are also really complex and require a lot of human effort.
