how to identify microservices

Tip: This article has been added to the. NET Core MicroServices Foundation Series indexFirst, the Docker minimalist introduction 1.1 General IntroductionDocker is an open source application container engine that is open source based on the Go language and complies with the APACHE2.0 protocol. Docker allows developers to package their apps and dependencies into a lightweight, portable container that can be published on any popular Linux machine or vir

NET core distributed project-Directory First, prepare prerequisites need to download and install Consul, project needs to understand add swagger Unified in the gateway to configure multiple microservices swagger, need to use the service registration and discovery, of course ocelot inside and have the service discovery, so need to put the ASP. NET core Project first registered in Consul. The landlord

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. NET Core version. 　　Version 1.Java Service call

restore the original master logic? For this problem, Hystrix also realized the automatic recovery function for us. When the circuit breaker opens, the main logic of the fuse, Hystrix will start a sleep time window, in this time window, the demotion logic is temporary into the primary logic, when the sleep time window expires, the circuit breaker will enter the semi-open state, release a request to the original master logic, if the request returned normally, Then the circuit breaker will continu

API Gateway is a very important part of the microservices architecture, there are many different services provided to external use, API gateway can be a unified portal, can also be done on the gateway for protocol conversion, permission control and request statistics and limit flow and other workSpring-cloud encapsulates the open source API gateway implemented by Netflix Zuul, and we can easily launch an instance of a Zuul gateway, support registering

Let's explore how

Application {public static void main(String[] args) {new SpringApplicationBuilder(ComputeServiceApplication.class).web(true).run(args);}}After we have completed the implementation of the service content, we will continue to do some configuration work for Application.properties, as follows:spring.application.name=eureka-clientserver.port=2001eureka.client.serviceUrl.defaultZone=http://localhost:1001/eureka/With the Spring.application.name property, we can specify that the name of the

Product mouth of a small project, from project to development on-line, with time and demand of the continuous explosion, will become more and more complex, become a large project, if the previous project structure is not well designed, code will become more and more bloated, difficult to maintain, late every product iteration on the line will be reaching. Project MicroServices, loosely coupled with the relationship between the modules, is a good choic

This section describes the following service management, and other features that will be introduced in the next few articlesService ManagementFor the service we need to manage the following actionsService machine: For the service deployment of the machine, we need the platform for management monitoring, if an exception occurs, through the API gateway to alarmMetadata: Through metadata we can find annotations of related services, such as name, own

Benefits:Solve the problem of traditional single-block style applications: Single code base, complex code maintenance Single release unit, difficult to test Single release unit, publishing difficulty Very high requirements for server hardware configuration, vertical expansion difficulties Unable to be stateless, horizontal expansion difficult Solve the problem of centralized service management mechanism: A single point of failure may occur Poor scalability, prone to

in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really a question that cannot be answered. So, in pr

This is a creation in Article, where the information may have evolved or changed. 1. Overview There is a scenario where a request will be processed by multiple services after the microservices split, and it will be difficult to troubleshoot if a service fails on the requested link.We may need to take the requested service, look at the log for analysis, and when the service has dozens of hundred instances, this is certainly scary. Therefore, in order t
