OpenShift Multi-Cluster Management Handbook

Hybrid Cloud Journey and Strategies

Do you want to learn about and operate OpenShift in multiple environments? If you are reading this book, we suppose that the answer is yes! But before we go into the technical details, we want to start this book by making you a proposition: any house construction starts with a foundation, right? In this book, our approach will be the same. We will start by giving you the foundation to understand and create a much stronger knowledge base – you will develop critical thinking and be able to make the best decisions for your use case.

That is why we decided to start this book by not talking about OpenShift itself yet, but by unveiling the most popular (and important!) context that it operates in: the hybrid cloud infrastructure. Therefore, in this chapter, you will be introduced to the hybrid cloud journey, challenges, dilemmas, and why many organizations are struggling with it. Knowing about these challenges from the beginning is a determinant success factor for hybrid cloud adoption.

Transforming an IT business so that it's agile and scalable but is also stable is a must-have nowadays, but that is not a simple step; instead, it is a journey from one star to another in the vast outer space of IT that currently surrounds us. However, why do we need those changes? Why is the market adopting the cloud massively and so rapidly? We'll discuss that shortly!

It is a changing world!

We are living in the age of fast changes! 10 years ago, most of the current big tech companies did not exist or were just small startups; several technologies that we have today also were only known within university research groups, such as 3D printing, artificial intelligence and machine learning, 5G, edge computing, and others – and there is much more to come! Technologies like the ones mentioned previously are becoming more popular and will create several demands that do not exist today, new job positions, and far more changes.

In this rapidly changing world, some new needs became important. Most companies were forced to change to be able to release new software and versions much faster than before, quickly scale resources, and have a global presence with responsive applications.

It was in this context that the public cloud providers have emerged with great success. However, several organizations that made huge investments in the cloud are experiencing some challenges. In a study conducted by IDG in 2020, among big companies in different industries and geographies, 40% of the respondents stated that controlling cloud costs is the biggest challenge when taking full advantage of it. This research has also shown data privacy and security as big obstacles. We will walk through some of these challenges in this chapter.

In this chapter, we will cover the following topics:

  • Main challenges of the public cloud
  • How a hybrid cloud strategy helps mitigate these challenges
  • How containers, Kubernetes, and OpenShift help to implement the hybrid cloud
  • OpenShift options
  • Types of OpenShift installations
  • Additional tools to support hybrid cloud adoption

Description

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.

Who is this book for?

This book is for a wide range of IT professionals using or looking to use OpenShift with a hybrid/multi-cloud approach. In this book, IT architects will find practical guidance on OpenShift clusters’ architecture, while Sysadmins, SREs, and IT operators will learn more about OpenShift deployment, troubleshooting, networking, security, and tools to manage multiple clusters from a single pane. For DevOps engineers, this book covers CI/CD strategies for multiple clusters using GitOps. Equipped with just basic knowledge of containerization and Kubernetes, you’re ready to get started.

As much as we would like it to be, OpenShift is not a single piece of technology - it's an entire stack of technologies many of which are complex in their own right, but together it can be a beast to comprehend. The benefits of OpenShift far outweigh the learning curve that comes with it so some of the most crucial technology services in the world rely on it. It's no wonder that OpenShift is one of, if not THE most in-demand skill set as of the writing of this review.I've read numerous books and countless guides and documentation on the topic of OpenShift, CICD, DevOps, Pipelines etc... and I've been impressed by what this book brings to the table. It's very well written with clear examples and intentions. You learn the "why's" while you learn the "what's".Why this book in particular? Because it is just the right amount of comprehensive. If you've ever waded into the world of OpenShift you'll know that there is a wealth of documentation available for free on the Internet, but you've probably also figured out that most of it is incomplete, incongruent, or too complex. This covers everything from deployment to troubleshooting, to application lifecycle management - a veritable "everything you wanted to know". You'll also get to learn about some pretty advanced topics such as RHACM and RHACS - two very powerful (IMO essential) tools for which there not enough documentation.The complexity of OpenShift leads much available documentation to focus on specific areas and assume a great deal about the reader's knowledge of everything else. For example, if you've ever tried to deploy a cluster while following documentation, you've probably come across a DNS section that said something like "Configure your DNS Server with the required entries." and just moved on expecting that you know what that means already. Maybe there was a link there that took you to some gigantic fifty page DNS document that wanted to tell you the history of Berkley before getting to the part that you actually needed to do the next step in your cluster install (assuming that the info was even there at all). Before you have that basic understanding it can sometimes be a challenge to even know what to search for to learn about it. In the case of the DNS example, this book just walks you through the process of installing BIND, creating zone files (from provided examples) and starting the service. In fact very little is taken for granted here.Where this book does make assumptions about your knowledge of containers, Kubernetes etc... it also refers you to specific named training (such as "Kube by Example") and resources to get you up to speed.Rather than be incomplete, some online documentation creates the opposite trouble - death by a thousand options. Since OpenShift and Kubernetes represent a lot of moving parts, there is a great deal of variability possible in the way you implement it. Much of the available documentation creates its own problem when it attempts to present every possible alternative. It's not always a matter of ten different ways to solve a problem either - sometimes the alternatives are matrixed with complex interdependencies (Like if you do A you have to do C & D, but if you do B you only have to do D). By contrast this book provides an opinionated approach while keeping branching to a minimum - you're left with carefully selected examples and instructions that are straightforward and will work for almost anyone.This book is easy to read, has great, practical examples (with code and everything) and takes very little for granted. It's great for beginners who want to get started with OpenShift and veterans who have maybe focused on a single area of the technology but want a more comprehensive understanding. If your company is in the midst of adopting OpenShift for the first time, or expanding your use of OpenShift in production, this book will be invaluable in helping you navigate that.
