Microservices vs Serverless Deployment in AWS: A Case Study with an Image Processing Application

Microservices and serverless are two major architectures used today for deploying cloud-native applications. There are ongoing debates concerning which of these two architectures to use for deploying a given application. In this paper, we have done a case study with an image processing application deployed in Amazon AWS. The study showed that serverless perform better in terms of performance, stability, cost, ease of deployment, and security, whereas microservices show superiority with lower memory use, and better controllability and visibility.
