'''Serverless computing''', also known as '''Function as a Service (FaaS)''', is a [[cloud computing]] code [[execution (computing)|execution]] model in which the cloud provider fully manages starting and stopping of function's container [[Platform as a service|Platform as a Service (PaaS)]] as necessary to serve requests, and requests are billed by an abstract measure of the resources required to satisfy the request, rather than per virtual machine, per hour.<ref name='techcrunch-lambda'>{{cite web|url=https://techcrunch.com/2015/11/24/aws-lamda-makes-serverless-applications-a-reality/|title=AWS Lambda Makes Serverless Applications A Reality|last=Miller|first=Ron|website=[[TechCrunch]]| date=24 Nov 2015|accessdate=10 July 2016}}</ref>
