Serverless Computing Cost Efficiency

Abstract

A software company in San Juan is currently modernizing the software product offering technologies for web apps. They wanted to understand how Serverless Computing can reduce costs. A proof of concept was done to refactor the web app and execute it into a Serverless architecture from an Infrastructure as a Service architecture. The Infrastructure as a Service architecture includes a Virtual Machine Web Server, while the Serverless architecture was done with the use of a Function App back end providing the web app front end from a storage static website. All these components were compared and appraised against the Virtual Machine Web Server costs. The Serverless Model is cost-effective and more convenient than the Infrastructure as a Service model. It is recommended that the software company in San Juan continue to pursue this option. Key Terms ⎯ azure functions, cloud, IaaS, SaaS.
