microservices fundamentals

In a distributed architecture, the role of the circuit breaker pattern is similar, when a service unit fails (similar to a short-circuit with electrical appliances), through the fault monitoring of the circuit breaker (similar to a fuse fuse), to the caller returned an error response, rather than a long wait. This does not cause the thread to fail to be released for a long time because of the invocation of the fault service, thus avoiding the spread of the fault in the distributed system.Netflix

rather than databases. But at first the idea was inspired by Shenli's article, "Micro-SOA: Principles of Service design and practices", which was thought of in conjunction with other ideas. The idea is only a utility model at present, the specific use of the effect also needs further verification, but only for the small and medium-sized development team, in the early implementation of the micro-service can completely replace the API gateway. is a comparison of the capabilities, implementation t

Spring Cloud is adapted to cloud services and is also suitable for enterprise informatization SOA construction. Spring boot is also a tool for the development of RESTful micro services. But for the intranet service, the call between service and service, spring does not deliberately encapsulate, perhaps they think it is not necessary, because already have thrift, ice and other powerful framework.If you use the RESTful service provided by spring boot itself as a call between service and service, t

In addition to supporting RABBITMQ's automated configuration, Spring Cloud bus supports Kafka, which is now widely used. In this article, we will build a Kafka local environment and use it to try the support of Spring Cloud Bus for Kafka to realize the function of message bus. Since this article will be modified based on the implementation of the previous rabbit, it is helpful to read the "Spring Cloud Building MicroServices Architecture (VII) message
