In this project, we’ll create six apps using Spring Boot, Quarkus, and Micronaut. For each framework, one app will use blocking Web with Tomcat, and the other will use non-blocking Reactive with Netty. We’ll build both JVM and Native Docker images. For Spring Boot, additional images will test configurations with Virtual Threads, CDS, and AOT
