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.

Container security

Container adoption grows exponentially, and with that also the number of vulnerabilities and potential attacks against all the container ecosystem. That being said, security is an important aspect you need to consider in your container strategy. Red Hat is well known for the high level of security of its products, which is one of the characteristics that has always been a differentiator for them in the industry, since the robust Red Hat Enterprise Linux (RHEL), which was (and still is!) the foundation of the company up to emerging technologies, such as Red Hat OpenShift. They have been named leaders in the container security space due to a number of security features that Red Hat defined as default (and required) with OpenShift that are optional in many other Kubernetes-based platforms, which also makes OpenShift more secure than other options. One example of it is Security-Enhanced Linux (SELinux), which is always enabled in any OpenShift worker nodes and prevents...
