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.

In the previous chapter, I already stated that there are multiple ways to use persistent storage in your container and I referred also to this chapter.

Kubernetes can configure persistent storage, but you have to provide it, for instance via a NFS container or by implementing StorSimple iSCSI Virtual Array (especially useful if you need read/write access from multiple containers). Even if you are using Azure storage there are many choices to make. Do you want to use disks, or the Azure File Storage? Do you want to create them on the fly (dynamic) or use existing ones (static)? Most of these questions are answered based on costs and the need for services such as replication, backup, and snapshots.

In this section, I want to cover the dynamic options; orchestration-wise, it's a better choice because you can do everything within Kubernetes (or tooling around...
