Learn how to develop modern Java applications using JBoss EAP 8 and deploy them

Developers frequently work with monolithic applications. However, the popularity of these monolithic applications has waned due to their lack of flexibility. Scaling a specific component requires scaling the entire application. Transitioning to a microservice architecture, with modular, independently scalable units addresses these challenges and is well-suited for cloud environments. This article focuses on moving a monolithic application, exemplified by a Java™-based e-commerce app called Pedal, to the cloud, offering guidance for this complex task.

This talk introduces the basic principles of optimization and pitfalls to avoid. We’ll dive into why the exact same techniques that make Quarkus rocket-fast were considered a terrible idea fifteen years ago; why fast benchmarks make for slow programs; why Project Loom may not be the speedup you’re hoping for; and why—even though it can be easy to get wrong—optimization really, really matters.
