Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure.

OpenStack is a collection of tools designed to create and manage cloud infrastructures by providing the needed components as a granular model that serves cloud computing-specific services. OpenStack was initially released in 2010 as a joint project between Rackspace and the National Aeronautics and Space Administration (NASA), is written in Python, and is licensed under the Apache 2.0 license.
