Azure Functions is an event-driven serverless compute platform in Azure and Azure Stack. Its open-source runtime also works on multiple destinations including Kubernetes, Azure IoT Edge, on-premises, and other clouds.

Azure Functions is a solution for easily running small pieces of code, or "functions," in the cloud. You can write just the code you need for the problem at hand, without worrying about a whole application or the infrastructure to run it. Functions can make development even more productive, and you can use your development language of choice, such as C#, F#, Node.js, Java, or PHP. Pay only for the time your code runs and trust Azure to scale as needed. Azure Functions lets you develop serverless applications on Microsoft Azure.
