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 Network

As we know, networking can be the cause of big trouble if it is not well designed. From a traditional perspective, the network is the dorsal spine of every infrastructure. Networking equipment such as routers, modems, switches, firewalls, Web Application Firewalls (WAFs), Intrusion Detection Systems/Intrusion Prevention Systems (IDSs/IPSs), proxies, and Virtual Private Networks (VPNs) needs to be totally integrated, deployed, and maintained using best practices to ensure high performance and reliable network infrastructure. In this chapter, we will discuss important concepts related to networking on OpenShift that you need to take into consideration to make the best decisions for your case.

This chapter covers the following topics:

  • OpenShift networking
  • Network policies
  • What is an Ingress controller?
  • Types of routes
