Azure Function Apps

Azure Functions is a solution for executing small lines of code or functions in the cloud. We can also select the programming languages we want to use. We pay only for the time our code executes; that is, we pay per usage. It supports a variety of programming languages, like C#, F#, Node.js, Python, PHP or Java. It supports continuous deployment and integration. Azure Functions applications let us develop serverless applications. Please refer to the official page of Azure Functions for more details
