Building reactive microservices with Vert.x 3.3
summary
Vert.x 3.3 adds out‑of‑the‑box Circuit Breaker (example: opens after three failures, retries after a timeout), Service discovery with bridges to Zookeeper and Kubernetes (demo on OpenShift using Hazelcast clustering and Docker builds), and HTTP/2 server/client with server push and custom frames (image-building demo drops ~8s HTTP/1.1 time to ~1–2s over HTTP/2). Event bus runs JSON/TCP across nodes, WebSocket bridge to browsers works, and MQTT and Kafka adapters extend device and streaming integration.
