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.

So, this brings us to the end of our overview of deployment options in Azure. Hopefully, this was useful and will help you have a better understanding of the benefits and concerns of each type of deployment option. One thing you probably noticed is that there is a lot of overlap between some of these services. You will need to consider other things when deciding on which option to use, such as what is the culture of development staff and how agile and flexible your modernized application needs to be. In the next chapter, we will explore modernization strategies at a high level. We will look at the patterns and best practices for running your legacy applications in Azure.
