Hands-On Linux Administration on Azure - Second Edition

By: Kamesh Ganesan, Rithin Skaria, Frederik Vos

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.

  • Fast to deploy, both manually and orchestrated, and, of course, you can customize them afterward
  • Easy-to-extend functionality and options with Azure extensions

If you are going with the native offerings there are some disadvantages or, in other words, some drawbacks:

  • If you want more hardening than the standard image, then you have to rely on hardened image versions from the Marketplace, which is expensive for some.
  • The standard...
