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.

Working with Microsoft Azure

Microsoft Azure, also known as Azure, is a public cloud service by Microsoft for building and deploying application services in the cloud. Azure provides a full offering of a highly scalable IaaS at relatively low costs, accommodating a wide range of users and business requirements, from small teams to large commercial enterprises, including financial, health, and governmental institutions.

In this section, we'll explore some very basic deployment workflows using Azure, such as the following:

  • Creating a Linux virtual machine
  • Managing virtual machine sizes
  • Adding additional storage to a virtual machine
  • Moving a virtual machine between resource groups
  • Redeploying a virtual machine
  • Working with the Azure CLI
