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.

Input and output bindings

Another optional but cool feature of Azure Functions are bindings. With bindings, you can bind input and output values to Azure resources. For example, in our first example, we triggered a queue message, which we then wrote to a blob manually. What if I told you we could do this with just a single line of code? In the upcoming section, we'll learn how to add bindings in the portal.

Adding bindings in the portal

You can add bindings in the Azure portal. Create a new Function App (one that isn't in read-only mode) to get started. Now, follow these steps:

  1. Create a new function.
  2. Pick the Azure Service Bus Queue trigger.
  3. Install the extension if you have to.
  4. Pick a name for your function or...
