What is Azure Functions?
Azure Functions is a platform for serverless applications. It lets developers host executable business logic without the need to provision infrastructure. Azure Functions offers inherent scalability, with pricing based solely on the utilization of resources. The language you choose to create your function code in can be C#, Java, JavaScript, Python, or PowerShell. In order to include well-known libraries into your business logic, support for package managers such as NuGet and npm is also provided.
