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.

Finding Your Way in the Filesystem

Now that you know how to manipulate and edit text files, it's time to see how these files are stored in the system. As a system administrator, you will have to check, mount, or even unmount the drives. So, now let's take a close look at the filesystem in Linux. The layout of the Linux filesystem is like all other members of the Unix family: very different from Windows. There is no concept of drive letters. Instead, there is a root filesystem (/), and everything else is available on the root filesystem, including other mounted filesystems.

In this section, you'll learn where you can find files, and why they are there.

The Filesystem Hierarchy Standard

In 2001, the Linux Foundation started the Linux Standard Base Project (LSB). Based on the POSIX specification, the idea behind this process was to have a standardized system so that applications can run on any compatible Linux distribution.
