Spring Cloud microservices architecture distributed across three physical nodes with Nginx load balancing, Spring Cloud Gateway routing, and Sentinel circuit breaking. Internet users connect through dual Nginx reverse proxies to Spring Cloud Gateway instances, which route traffic to replicated Microservice A and B instances across all nodes while maintaining service discovery via Eureka Server clusters. The design integrates Redis Sentinel for distributed caching with master-replica failover, XXL-JOB for distributed job scheduling, FastDFS for file storage, and DM DB for primary-replica database replication. This production-grade topology demonstrates enterprise patterns for service resilience, data consistency, and horizontal scalability.
