Look inside

You’re a senior developer at Travel World Agency (TWA), which has grown to become the largest travel agency in the world. The company has built a next-generation system that uses a microservice architecture running on Amazon Web Services (AWS). But while TWA’s success has been steadily climbing, the performance of its reservation microservice has been losing altitude. As a solution, TWA has replaced the microservice with a new one. Your job is to improve performance by leveraging cache mechanisms, including the Caffeine, Varnish, and Redis libraries, that will reduce traffic between APIs.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
