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.

Our migration journey started in Chapter 3, Assessment and migration planning, where we saw the importance of assessment and its contribution to the overall migration journey.

In Chapter 4, Performing migration to Azure, we witnessed the actual migration of Linux workloads to Microsoft Azure Virtual Machines as well as to managed services. Chapter 5, Operating Linux on Azure, was more about the post-migration strategies and tools for optimizing and securing workloads in Azure.

At this point, we have our virtual machine (VM) successfully migrated to Azure. Time to pack your bags and consider the job well done. However, sometimes things don't work the way they should. You might be getting strange errors in your log files or your client might be complaining that the migrated application is behaving incorrectly. You could even find out that your VM doesn't boot at all.
