There is no doubt that although we have not yet incorporated it into the technical selection of the produc

In a microservices architecture, a service is the smallest, scalable, standalone deployment unit that can have multiple instances of the same service offering, which are registered to the Service registry (Eureka Server) for unified management and load balancing of calls.Because spring cloud is already Java as the main development language, this article will first speak the Java language of the service how to register to the service center, and then f

I. Background Under the microservices architecture, our systems are split into multiple, single-duty microservices based on business. Each service has its own set of APIs to provide to other service calls, so how to ensure security. It is not that you want to invoke the call, we must have the authentication mechanism, is the request from our internal service, we can call our interface. Note that we are tal

Part VI: Go microservices-Health Check As our microservices become more and more complex, it is important to have a mechanism that lets Docker swarm know that a service is healthy. Therefore, this article focuses on how to add a health check for a microservices service. If the Accou

ObjectiveBefore, I have said a lot about the concept of micro-services, after all, many people will see after the idea of no meaning, because there is no practical thing to say, even if each concept is understood, it is difficult to give practice. So this time, let me illustrate with a practical example of how we will build our microservices in the actual project process.PS: We just use the scene to simulate the entire process of our

1 , prefaceSurging by everyone so much attention, I am very surprised, such as a colleague in the company sharing the surging, as well as in the blog with other RPC framework, micro-service to do the comparison, and so on, these actions have made me feel very stressed, after all, as a personal open-source project, It is not possible to compare with the mature open source community projects, but also wait until there are many like-minded friends to join together to develop and perfect surging, so

Spring Cloud combines today's more mature, proven service framework with the spring boot style for re-encapsulation, masking complex configuration and implementation principles, and ultimately integrating a simple, easy-to-deploy and maintainable Distributed system architecture platform.Spring Cloud's sub-projects can be broadly divided into two categories: the package and abstraction of Spring boot for existing mature frameworks, and the largest number of projects, and the second is the impleme
