MicroServices are a very hot architecture or concept at the moment, and they are the architectural way to build large-scale Internet projects.1. Single StructureA monolithic architecture is the application of a well-developed project into a war package, which is then published to a container such as Tomcat.Assuming you are preparing to develop a taxi scheduling software that competes with Uber and Hailo, you may start this new project manually or usin

One: What is microservices (microservice)MicroServices English Name Microservice,microservice schema mode is to organize the entire Web application into a series of small Web services. These small Web services can be compiled and deployed independently, and communicate with each other through their exposed API interfaces. They work together to provide functionality to the user as a whole, but can be expande

What is micro-service?The traditional single service architecture is a separate service package, sharing code and data, development cost is high, maintainability, scalability is poor, technology transformation, cross-language cooperation is relatively difficult. While the MicroServices architecture emphasizes that a service is responsible for a business, the service can be deployed separately, the technology is selected and developed independently, th

automatically has the function of registry, load Balancing, failover. hystrix There are often multiple service layer calls in the MicroServices architecture, and the failure of the underlying service can lead to cascading failures, which in turn will result in the entire system being unavailable. This phenomenon is called the service avalanche effect. The service avalanche effect is a process in which the service consumer is not available and

business split into a lot of sub-business, and then for each sub-business cluster deployment, so that each sub-business if the problem, the entire system will not be affected. Excerpt from: What is the difference between a distributed and a cluster? Distributed concept reference: Features and design concepts of distributed systems In addition, there is a concept similar to the distribution, that is, microservices.

, dependent on the call relationship between services and communication protocols are clear2. Avoid splitting for splitting3.

First, IntroductionThe hystrix provides almost real-time monitoring. When executed, Hystrixcommand and Hystrixobserv-ablecommand generate execution results and run metrics, such as the number of requests executed per second, number of successes, and so on, which are useful for analyzing the state of the application system.Using the Hystrix module hystrix-metrics-event-stream, these monitored metrics information can be exposed to the external system in a Text/event-stream format.
