ibm microservices architecture

all services that are obtained in the implementation of Eureka through the Discoveryclient interface defined by spring cloud. Since spring cloud has done a very good job of abstraction in the service discovery layer, for the above program, we can seamlessly switch from Eureka's service governance system to Consul's service governance system Central.From now on, I will record the process and the essence of the recently developed Springcloud micro-service cloud

Spring cloud itself provides a lot of components, but we need to follow the business model to customize the enterprise needs of the common architecture, then we need to consider what technology to use now?Below I have made the following technical summary for the spring Cloud Micro-service distributed cloud architecture, hoping to help you:View:H5, Vue.js, Spring Tag, React, AngularJsSpring boot/spring Cloud

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 o

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

Spring cloud itself provides a lot of components, but we need to customize the common architecture that the enterprise needs according to the business model of the enterprise.

/consumer, and we will get the return result: fallback. We can see from the console of the eureka-client that the service provider outputs the results that were originally to be returned, but because the service consumer triggered a service request timeout exception due to a delay of 5 seconds before it was returned, the service consumer was executed by the downgrade logic specified in the Hystrixcommand annotation , so the result of the request returned fallback. Such a mechanism provides the b

DcClient dcClient; @GetMapping("/consumer") public String dc() { return dcClient.consumer(); }}The way to implement service invocation through spring Cloud feign is much simpler, with the interface defined by @feignclient to unify the life we need to rely on for the MicroServices interface. And in the specific use of the call to the local method a little bit of the call. Since feign is implemented based on the Ribbon, it comes with

A microservices architecture system, the different services will be called each other, such as an order service needs to fetch user data, you need to invoke user services, there are multiple User Service instances, Eureka load balanced to one of the service instances, and the previous chapter, We first use the Java version of the service discovery and invocation service to do examples and porting to the.
