Modernizing Legacy Applications to Microsoft Azure

By: Steve Read, Larry Mead

Overview of this book

Organizations have varying circumstances, objectives, and prerequisites when contemplating a hyper-scale cloud solution transformation to a platform such as Azure. Modernizing Legacy Applications to Microsoft Azure uncovers potential scenarios and provides choices, methodologies, techniques, and prospective possibilities for transitioning from legacy applications to the Microsoft Azure environment. You’ll start by understanding the legacy systems and the main concerns regarding migration. Then, you’ll investigate why distributed architectures are compelling and the various components of the Azure platform needed during migration. After that, you’ll explore the approaches to modernizing legacy applications and the Rs of modernizing (i.e., rehost, refactor, rearchitect, and retire). You’ll also learn about integration approaches and potential pitfalls. By the end of this book, you’ll be well equipped to modernize your legacy workloads while being aware of pitfalls and best practices.

In this chapter, we explored some of the most important topics you will need to consider when modernizing your monolith. Much of the microservices world is still emerging, so you will need to do your research to decide which of the topics we covered are relevant to your journey. Keep in mind, as we stated earlier in this chapter, that there is no one size fits all approach here. There are multiple paths to consider based on your vision of where you want to go and the workloads you are considering for modernization.

In the next chapter, we will wrap things up with a look at trends and emerging technologies that you need to be aware of to have a successful transformation journey.
