Implementation and Analysis of a Serverless Shared Drive with AWS Lambda

Serverless computing is an emerging new paradigm in cloud computing. Serverless denotes a special kind of software architecture in which application logic is executed in an environment without visible processes, operating systems, servers or virtual machines. Serverless enables the deployment of applications and services to the cloud as code snippets or functions as opposed to a monolithic program. While serverless is rapidly evolving, it lacks a standard definition and general consensus within the technical community but has the potential to massively alter the way in which software delivers business value. This work presents the architecture and implementation of a shared drive web application using AWS Lambda. The application is tested to compare the response time for cold and warm requests, effect on load balancing, performance on memory reservation and resource retention behavior. Additionally, the gaps and limitations in current serverless architecture are discussed.
