No Rocket Scientist Required - Developing +14,000 Message p/second IOT Systems
summary
Claims a high-throughput IoT pipeline and shows how it was proven and fixed: generates large load by embedding JMeter in a Spring Boot app and scaling to 14 app instances on Cloud Foundry, inspects containers via CF SSH + JMX + VisualVM, finds the monolith database/persistence and downstream pushes are the bottleneck, solves them by breaking into microservices with RabbitMQ buffering and using the @Async thread pool for writers, which cuts a 1m30s processing job to under 15s.
