Developers upload their code to Google’s cloud, and the functions are run in a managed Node.js environment. There is no need for users to manage or scale their own servers. “[Cloud Functions] enables true server-less development,” Google’s Ben Galbraith said. Like AWS Lambda and Microsoft’s Azure Functions, Cloud Functions allows users to deploy and run code without provisioning servers. Developers code to cloud APIs, and the cloud takes care of managing and scaling the functions.
