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.

Summary

In this chapter, we looked at some of the strategies that provide services for multiple tenants with OpenShift clusters. You now understand that we can have dedicated or shared OpenShift clusters to host tenants. You also saw that with shared clusters, you can provide some level of isolation for each tenant by using namespaces, ResourceQuotas, NetworkPolicies, and other objects to provide multitenancy or even have a physical separation of workers and/or ingress; the best option for your use case depends on the requirements of your organization, workloads, and environments.

However, I need to warn you that in the current hybrid cloud world, you will probably need to work with clusters in different providers and regions, which may lead you to have an increasing number of clusters. But don't worry – as we saw in Chapter 1, Hybrid Cloud Journey and Strategies, many great tools can help us manage several clusters, such as Red Hat Advanced Cluster Management, Advanced...
