Personal understanding is that Spring Cloud Spring Cloud Alibaba micro-service specification an implementation, plus some of Ali cloud business components
What is Spring Cloud
Spring Cloud offers a number of distributed components for developers so they can quickly build distributed systems (for example, configuration management, service discovery, circuit breakers, intelligent routing, micro broker, a control bus, a one-time token, global lock leadership election, distributed session, cluster state).
Developers using Spring Cloud components, implementation of distributed service system, so that the service can work in any distributed environment.

There was a very good text summary, for everyone to share:
Spring usually refers to the IOC Spring
Spring Framework contains the Spring IOC, includes both Spring AOP, and achieve integration with other J2EE frameworks
Spring Boot complements the Spring Framework, so that integration becomes simpler framework, committed to the rapid development of independent Spring applications
Spring Cloud Spring Boot design is based on a set of micro-service standards, and enhanced application context
Spring Cloud Alibaba Ali middleware uses as a raw material to achieve a micro-Spring Cloud service specification
