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

authentication, flow control, and shunt control. 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

Microservices-webapi implementation, separation from iis, and tomcat-webapitomcatPreface Microservice, as its name implies, is a tiny, single service program, a single process, a single release, development and deployment can be independent; This is my understanding; However, web-based services, such as webservice and webapi, must be based on iis or tomcat, This article describes how to deploy plain text programs based on http services by bypassing ii

Run (args);} By default, the service registry will also try to register itself as a client, so we need to disable its client registration behavior by simply application.properties adding the following information to the configuration file: 123456 s

Create a basic spring boot project, named Eureka-server, and introduce the required dependencies in the Pom.xml:Start a service registry with @enableeurekaserver annotations to provide conversations to other apps. This step is very simple, just add this annotation to a normal spring boot application to enable this feature, such as the following example:@EnableEurekaServer@SpringBootApplicationpublic class Application {public static void main(String[] args) {new SpringApplicationBuilder(Applicati
