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. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud. If you also find yourself adopting DevOps practices in the process, we'll consider our mission accomplished.

Introducing IaaS solutions

IaaS is the backbone of cloud computing. It offers on-demand access to resources, such as compute, storage, network, and so on. The CSP uses hypervisors to provide IaaS solutions. In this section, we provide you information about some of the most widely used IaaS solutions available. We will give you details about providers such as Amazon Elastic Compute Cloud (Amazon EC2), Microsoft Azure Virtual Machines, and Google Compute Engine (GCE) as the big players, and DigitalOcean as a viable solution.

Amazon EC2

The IaaS solution provided by AWS is called Amazon EC2. It provides a good infrastructure solution for anyone, from low-cost compute instances to a high-power graphics processing unit (GPU) for machine learning. AWS was the first provider of IaaS solutions 12 years back and it is doing better than ever, even after the COVID-19 pandemic (
