Developers use Azure Functions to connect to data sources or messaging solutions and react to events. The best part about Azure Function is its compute-on-demand capacity which means that you only pay for the services when you consume the resources. Azure Functions, a serverless compute service, enables enterprises to run event-triggered codes without having an infrastructure for its provision.
Azure Function is greatly reliable and is used in production settings. It can be used to achieve decoupling, high-throughput, shared, and reusability.
