Bank clearing system
summary
A small bank clearing system is built from Spring Boot microservices wired by the JLupin server platform, using Maven and an IntelliJ plugin, REST endpoints for external calls and a faster binary Java protocol between services. Deployment runs each microservice as its own OS process with an atomic routing switch for zero-downtime rolling deploy; a demo injects 10,000 customers, the update completes with one client request failure, otherwise the platform runs and hot-swaps services.
