Since the platform deals with one function at a time, and functions are the fundamental deployment units, this model is often called as Functions as a Service (FaaS).

These are then assembled together to deliver a unique feature or functionality of an application. So, a function is to FaaS what a VM is to IaaS.There are three critical attributes to a serverless platform… (read more).
