Exploring Alternative Spring Cloud Implementations
summary
Compares concrete Spring Cloud interfaces — DiscoveryClient, LoadBalancerClient, Configuration and Bus — across Eureka, Consul, ZooKeeper and etcd and shows working code for each: ZooKeeper via Curator and Exhibitor with hierarchical keys, Consul as an HTTP key‑value store plus agent, etcd using TTL nodes for registration, and Eureka’s AP behavior at scale; bus initially uses RabbitMQ but is being rewritten to Spring Cloud Stream to be broker‑agnostic; demonstrates tracing with Spring Cloud Sleuth/Zipkin; bus demo fails but discovery/config demos work.
