It’s called functions as a service, and it’s amazing. The concept is based on Serverless computing. It gives us the ability to deploy any individual piece of code, or function. The code runs and returns a value, in turn ending the process. Sounds simple, right? Well, it is. If you’ve ever written a REST API you’ll feel right at home. All the services and endpoints you would usually keep in one place are now sliced up into a bunch of tiny snippets, microservices. The goal is to completely abstract away servers from the developer and only bill based on the amount of times the functions have been invoked. Meaning services such as these are easy to scale.
