Who this book is for

This book is directed toward two groups of system administrators—those who want a detailed, step-by-step guide to setting up a high-performance and high-availability CentOS 7 cluster and those who are looking for a reference book to help them learn the necessary skills to ensure that their systems and the corresponding resources, and services are being utilized at their best capacity. No previous knowledge of performance tuning is needed to start reading this book, but the reader is expected to have at least some degree of familiarity with any spin-off of the Fedora family of Linux distributions, preferably CentOS.
