Multi-node Spring Cloud microservices architecture with distributed scheduling, service discovery, and data persistence across three clustered nodes. Users route through Nginx load balancers to Spring Cloud Gateway instances, which coordinate with Eureka Server for service discovery and Sentinel for resilience, while XXL-JOB handles distributed task scheduling across executor nodes. Redis Sentinel provides in-memory caching with master-replica failover, FastDFS manages distributed file storage, and DM DB ensures database consistency with primary-replica replication. This topology demonstrates production-grade patterns for fault tolerance, horizontal scaling, and operational observability in enterprise Java applications.
