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.

What is multitenancy?

Multitenancy is the ability to provide services for multiple users or groups (also known as tenants) using a single platform instance. A platform architecture can be designed to be single- or multi-tenant:

  • In a single-tenant platform architecture, there is no isolation within an instance of the platform. This means that there is no separation in an instance and that, as such, there is no way to isolate objects for users or groups. In this case, to achieve multitenancy, you need to provision a separate platform instance for every tenant.
  • In a multi-tenant platform architecture, it is possible to isolate objects and data between different tenants. Therefore, you can protect each tenant's data and objects, thus providing enough privacy and security, even by using a single platform instance.

Depending on the architectural design and how OpenShift is used, you can have both types of platforms (single- or multi-tenant). In this chapter, you will...
