Migrating Linux to Microsoft Azure

By: Rithin Skaria, Toni Willberg

Overview of this book

With cloud adoption at the core of digital transformation for organizations, there has been a significant demand for deploying and hosting enterprise business workloads in the cloud. Migrating Linux to Microsoft Azure offers a wealth of actionable insights into deploying Linux workload to Azure. You'll begin by learning about the history of IT, operating systems, Unix, Linux, and Windows before moving on to look at the cloud and what things were like before virtualization. This will help anyone new to Linux become familiar with the terms used throughout the book. You'll then explore popular Linux distributions, including RHEL 7, RHEL 8, SLES, Ubuntu Pro, CentOS 7, and more. As you progress, you'll cover the technical details of Linux workloads such as LAMP, Java, and SAP, and understand how to assess your current environment and prepare for your migration to Azure through cloud governance and operations planning. Finally, you'll go through the execution of a real-world migration project and learn how to analyze and debug some common problems that Linux on Azure users may encounter. By the end of this Linux book, you'll be proficient at performing an effective migration of Linux workloads to Azure for your organization.

Popular workloads on Linux

In real-world scenarios, we only migrate servers with workloads running on them, as there is no point in migrating a VM with no services running to the cloud. Instead of doing that, you could deploy a new server in Azure directly and start developing on top of that. Let's have a quick recap of the popular workloads on Linux. Some of these were already explained in Chapter 1, Linux: History and future in the cloud. Let's recall the varieties of workloads, including application hosting (such as Java and LAMP), Search, and big data, and see how Azure supports these.

LAMP

The acronym LAMP stands for Linux, Apache, MySQL, PHP/Perl/Python. Typically, it is the first service stack that any Linux administrator would set up and is usually used to host dynamic and database-driven websites. In LAMP:

  • Linux (L) refers to any Linux distribution; you can use Ubuntu or Fedora or CentOS or any other distribution.
  • Apache (A) is the web server that...
