Questions tagged [spring-cloud]

Spring Cloud provides tools to quickly build common patterns in distributed systems (e.g. configuration management, service discovery, circuit breaker, intelligent routing, micro-proxy, control bus, global locks, leadership election, distributed sessions). Coordination of these systems leads to boiler plate patterns, and using Spring Cloud you can quickly create applications that implement those patterns.

Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems (e.g. configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, control bus, one-time tokens, global locks, leadership election, distributed sessions, cluster state). Coordination of distributed systems leads to boiler plate patterns, and using Spring Cloud developers can quickly stand up services and applications that implement those patterns. They will work well in any distributed environment, including the developer's own laptop, bare metal data centres, and managed platforms such as Cloud Foundry.
