What is Serverless?
Serverless is a computing model where code is directly deployed on compute resources in a way that is abstracted from the developer. Also know as Function As A Service (FaaS), serverless computing is designed to simplify the process of deploying and scaling code in production. A serverless framework automatically addresses key operational concerns such as elastic scaling, deployment, and routing. Common serverless frameworks include Serverless, Knative, and OpenFAAS.
