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.

Managing Network Resources

As discussed earlier, in Chapter 3 Basic Linux Administration, networking is very important. Azure Virtual Network is an Azure service that provides the following:

  • Connectivity to your workload
  • Connectivity from your workload to the outside world
  • Connectivity between VMs
  • Other connectivity options, such as VPN tunnels
  • Traffic filtering
  • Advanced routing options, including BGP routes through a VPN tunnel

Virtual Network

In Azure, the most important component of virtual networking is the virtual network, or VNet for short. A virtual network is crucial as it provides a highly secure isolated environment for your VMs to run in.

The following process might appear a little confusing and lengthy, but the intent here is to make you understand the process and commands. Let's start with the creation of a virtual network:

AzVirtualNetwork -Name <vnet name> '
