The main function of Zuul is to route forwarding and filtering, for example, to forward all/api-a/* requests to Server A, all/api-b/* requests are forwarded to Server B, zuul default and ribbon combine to achieve load balancing function.1 Zuul Routing and forwarding1.1 Creating a Springboot project, introducing dependent dependenciesProjectxmlns= "http://maven.ap

In the micro-service architecture, several basic service governance components are needed, including service registration and discovery, service consumption, load balancing, circuit breakers, intelligent routing, configuration management, etc., which are co-organized by these basic components to form a simple microservices system. A brief micro-service system such as:Note: A service and b services can be called each other, when the drawing is forgotten. And the configuration service is also regi

internal microservices APIs to be exposed.Blog System ArchitectureBased on an architectural design of our microservices as a whole, this series of blogs is primarily a demonstration of the entire microservices architecture. The concept of a gateway can be more deeply understood through a set of schema comparisons.Traditional Internet architectureIn the architecture without microservices, we generally use nginx as the load distribution, reverse proxy, to form a building of an API gateway.

This essay goes on to learn a more important Component API Gateway service in MicroServices. When we finally have to provide external access to the micro-service architecture, we need a unified access portal, to hide our internal service URL details, which is a bit like the concept of the gateway in the LAN, this is the API Gateway Service has emerged. API Gateway is capable of providing the basic functions of request routing, load balancing, checking and filtering, as well as advanced functions
