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 is rocketing higher, the performance of its reservations microservice is crashing and burning. As a solution, the company has replaced the microservice with a new one, using Kotlin and Spring Boot to improve performance and maintainability. Your job is to improve the performance of the new API.

With the help of the Maven Enforcer plugin, you’ll deal with dependencies that slow the microservice. You’ll use ktlint to format the source code according to a single standard, thereby increasing efficiency. You’ll create a Docker image using GraalVM and optimize it to decrease resource consumption. When you’re finished, your API will start up quicker and be more reactive, even on high-traffic days like Black Friday and Cyber Monday!
