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.

Is hybrid cloud the solution?

As we've already discussed, the public cloud, while it can solve some challenges, introduces others. It was in this context that the hybrid cloud emerged: to mitigate some of the challenges and take the best from each provider, from on-premises, private, or cloud providers. The HashiCorp State of Cloud Strategy Survey, which was made in 2021 with more than 3,200 technology practitioners, found that multi-cloud is already a reality. 76% of the respondents stated that they are using multiple cloud vendors, with expectations for this to rise to 86% by 2023.

So, what are the characteristics of the hybrid cloud that help mitigate the challenges of public cloud adoption? Here are a few of them:

  • Best-of-breed cloud services from different vendors can be combined, enabling a company to choose the best option for each workload.
  • The ability to migrate workloads between different public and private cloud environments, depending on the actual circumstances.
  • Being able to have a single, unified orchestration and management across all the environments for all providers.

The following table lists some of the challenges and hybrid cloud mitigations:
