Explore reactive microservices with Vert.x in this comprehensive Devoxx conference talk. Dive into the world of high-demand, high-scale distributed systems and learn how to leverage reactive programming for improved scalability. Discover Vert.x, a lightweight, fast, modular, and high-performance toolkit for building reactive applications on the JVM. Follow along with live demonstrations showcasing how to create reactive code using Java, Groovy, JavaScript, and other JVM languages. Gain insights into building Vert.x-based systems that utilize the unique Vert.x event bus for real-time communications between modern web browsers and the cloud. Explore key microservices principles, reactive systems, and programming concepts, including verticles, event loops, and JSON decoding. Learn about microservices patterns, API gateways, and circuit breakers to prevent cascading failures. By the end of this talk, reconsider traditional monolithic architectures and embrace an event-driven, reactive, microservice-focused approach to application development.
