Overview of this book

Thanks to its flexibility in delivering scalable cloud solutions, Microsoft Azure is a suitable platform for managing all your workloads. You can use it to implement Linux virtual machines and containers, and to create applications in open source languages with open APIs. This Linux administration book first takes you through the fundamentals of Linux and Azure to prepare you for the more advanced Linux features in later chapters. With the help of real-world examples, you’ll learn how to deploy virtual machines (VMs) in Azure, expand their capabilities, and manage them efficiently. You will manage containers and use them to run applications reliably, and in the concluding chapter, you'll explore troubleshooting techniques using a variety of open source tools. By the end of this book, you'll be proficient in administering Linux on Azure and leveraging the tools required for deployment.

Software Management

In any operating system, we need to install some software that will help us to do our day-to-day work. For example, if you are writing scripts, the stock software or application that comes with the operating system might not be enough. In that case, you need to install software such as Visual Studio Code to make your work easier. Likewise, in a corporate environment, you might need to add new software or even update existing software to meet your business requirements.

In the old days, installing software was a matter of extracting an archive to a filesystem. There were several problems associated with this approach, however:

  • It was difficult to remove the software if the files were copied into directories also used by other software.
  • It was difficult to upgrade software; maybe the files were still in use, or they were renamed for whatever reason.
  • It was difficult to handle shared libraries.

That's why Linux distributions invented...
