principles of microservices

Spring Cloud Config is a new project created by the spring Cloud team to provide centralized external configuration support for infrastructure and microservices applications in distributed systems, which are divided into two parts: server and client. The server, also known as the Distributed Configuration Center, is a standalone microservices application that connects to the configuration warehouse and prov

1. Distributed A large system is divided into several business modules, and the business modules are deployed to different machines, and each business module interacts with the data through the interface. The difference between distributed methods is based on different machines and different businesses. above: Service A, B, C, D are business components, business access through API Geteway, respectively. Note: Distributed needs to do transaction management. Distributed transactions can be

This is a creation in Article, where the information may have evolved or changed. Part III: Go microservices-embed databases and JSON In the third part, we let accountservice do something meaningful. Declares an account structure. Embedded in simple key-value storage, we can store the account structure inside. Serializes the struct into JSON and then serves the/accounts/{accountid} through the HTTP service. Source Source code location:

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

In the Wetext Project: A demo case of the DDD, CQRS, and microservices architecture based on. NET implementation, I introduced the ddd/cqrs/I developed with Visual Studio (C # 6.0 with. NET Framework 4.6.1) Case Project for MicroServices Architecture: Wetext. After the article issued a very good response, but also thank you for your attention. In this article I'll show you how to run the service side of the

Permission control is an important function in a system. Zhang San can only access specific features of input Zhang San, John Doe cannot access specific menus that belong to Zhao Liu. This requires the entire system to do a perfect authority control system. The system should have a pin to distinguish between users, permissions, roles and other necessary functions.
