Linux Service Management Made Easy with systemd will provide you with an in-depth understanding of systemd, so that you can set up your servers securely and efficiently.This is a comprehensive guide for Linux administrators that will help you get the best of systemd, starting with an explanation of the fundamentals of systemd management.You’ll also learn how to edit and create your own systemd units, which will be particularly helpful if you need to create custom services or timers and add features or security to an existing service. Next, you'll find out how to analyze and fix boot-up challenges and set system parameters. An overview of cgroups that'll help you control system resource usage for both processes and users will also be covered, alongside a practical demonstration on how cgroups are structured, spotting the differences between cgroups Version 1 and 2, and how to set resource limits on both. Finally, you'll learn about the systemd way of performing time-keeping, networking, logging, and login management. You'll discover how to configure servers accurately and gather system information to analyze system security and performance. By the end of this Linux book, you’ll be able to efficiently manage all aspects of a server running the systemd init system.

Understanding the purpose of cgroups

Back in the days of single-core CPUs, resource management wasn't such a big deal. Servers generally came with anywhere from one to four single-core CPUs installed, so they were already limited in the number of services that could run simultaneously. All we needed for resource management back then were simple tools such as nice, renice, and ulimit.

Nowadays, it's an entirely different story. Servers now come with one or more multi-core CPUs and gobs of memory. (The current king-of-the-hill server CPU is the AMD Epyc, which now comes in a 64-core variety that can run 128 simultaneous threads. Yeah, that's enough to make us hard-core geeks salivate.) Although it might seem counter-intuitive, resource management on these beasts is more important than it was on the old systems. That's because one server can now run multiple services, multiple virtual machines, multiple containers, and multiple user accounts all at the same time...
