An introduction to Azure Functions

Azure Functions is a service that Microsoft offers for customers to run Functions on Azure Platform. Azure Functions is Microsoft's implementation of Functions as a Service (FaaS). Its main goal is to enable developers to run small pieces of software code or functions to be run in the Microsoft Azure cloud. If you recall the benefits of FaaS that we learned in Chapter 1, What is Serverless Computing? one of them is that, the developer is just focused on writing the code to solve the problem at hand, rather than, worrying about infrastructure on where it will run. The developer need not worry about the entire application that is required to run the code and scaling the infrastructure as well when the function receives a lot of traffic. As the developers are focusing on just solving the problem at hand, development can be more productive.
