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.

Multi-cluster observability with Red Hat ACM

Multicluster observability is an ACM feature that is intended to be a central hub for metrics, alerting, and monitoring systems for all clusters, whether hub clusters or managed clusters.

As this tool handles a large amount of data, it is recommended to provide fast disks as its storage backend. Red Hat has tested and fully supports the solution if adopted in conjunction with Red Hat OpenShift Data Foundation.

Although Red Hat recommends doing so, the prerequisite is a storage solution that provides object/S3-type storage, such as those commonly found in most cloud providers (such as Amazon S3).

Prerequisites

Since observability is a feature of an ACM operator, there aren’t many prerequisites. The following are the requirements:

  • Enable the observability feature on a connected Red Hat OpenShift cluster.
  • Configure an object store from a storage provider. Some of the supported object storage types are as follows...
