Overview of this book

Whether you are trying to re-architect a legacy app or build a cloud-ready app from scratch, using the Azure ecosystem with .NET and Java technologies helps you to strategize and plan your app modernization process effectively. With this book, you’ll learn how to modernize your applications by using Azure for containerization, DevOps, microservices, and serverless solutions to reduce development time and costs, while also making your applications robust, secure, and scalable. You will delve into improving application efficiency by using container services such as Azure Container Service, Azure Kubernetes Service (AKS), and more. Next, you will learn to modernize your application by implementing DevOps throughout your application development life cycle. You will then focus on increasing the scalability and performance of your overall application with microservices, before learning how to add extra functionality to your application with Azure serverless solutions. Finally, you’ll get up to speed with monitoring and troubleshooting techniques. By the end of this book, you will have learned how to use the Azure ecosystem to refactor, re-architect, and rebuild your web, mobile, and desktop applications.

Creating Azure Functions in Visual Studio

So far, we have only created functions in the Azure portal, but this isn't ideal. First, the portal doesn't provide proper tools for writing complex code. Second, your code isn't included in source control. Third, your code isn't covered in unit tests and automated builds. Finally, you can never deploy your functions to other environments through continuous deployment. So, while it's nice for simple use cases, try to avoid creating functions in the portal and use Visual Studio instead.

Now, we are going to create our functions using Visual Studio 2017. To follow along with these examples, you need to have the Visual Studio Azure development workload installed, which you can select when you install or modify Visual Studio. To check whether you have it or not, open Visual Studio, create a new project, and look...
