Hands-On Linux Administration on Azure

By: Frederik Vos

Overview of this book

Azure’s market share has increased massively and enterprises are adopting it rapidly, while Linux is a widely-used operating system and has proven to be one of the most popular workloads on Azure. It has thus become crucial for Linux administrators and Microsoft professionals to be well versed with managing Linux workloads in an Azure environment. With this guide, system administrators will be able to deploy, automate, and orchestrate containers in Linux on Azure. The book follows a hands-on approach to help you understand DevOps, monitor Linux workloads on Azure and perform advanced system administration. Complete with systematic explanations of concepts, examples and self-assessment questions, the chapters will give you useful insights into Linux and Azure. You’ll explore some of Linux’s advanced features for managing multiple workloads and learn to deploy virtual machines (VMs) in Azure. Dedicated sections will also guide you with managing and extending Azure VMs’ capabilities and understanding automation and orchestration with Ansible and PowerShell DSC. In later chapters, you’ll cover useful Linux troubleshooting and monitoring techniques that will enable you to maintain your workload on Azure. By the end of this book, you’ll be able to make the most out of Azure’s services to efficiently deploy and manage your Linux workloads.

Chapter 9: Container Virtualization in Azure

  1. Many similar applications with the same needs, such as OS dependencies and software installed. On top of that, you need availability and scalability.
  2. Exactly the opposite. If there are many different workloads, it's often not worth the effort. Another reason is security: containers are much harder to protect.
  3. In general, a virtual machine is the solution here, but LXC is a very usable solution. It's somewhere between a virtual machine and a container in terms of creating and managing it.
  4. Tools such as Buildah make it possible to create virtual machines that can be used in every solution. Rkt also supports the Docker format. The Open Container Initiative is working very hard to create standards to make it even easier.
  5. Development can be pretty expensive if you do everything in the cloud. Developing locally and then pushing...
