microservices deployment

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

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
