Server-Less Cloud Computing—An Economical Solution for Business Operations

Abstract

Cloud computing provided computing resources which were not imagined before by any business as solutions for their operations. Since the last five years, a new paradigm of service model has emerged which is Function as a Service (FaaS). FaaS is also referred to as server-less computing where the stateless function is responsible for computation of data. These functions are deployed on Amazon Web Services (AWS) Lambda along with other services like API Gateway and DynamoDB to efficiently run the application. The data is transferred using HTTP which is a stateless protocol and it uses its GET and POST methods to exchange data. In this paper, we analyze the deployment of an API on a conventional cloud computing model and compare it with the server-less model, taking account of all the API calls that generate costs.
