Why to use ZuulLet's take a look at the diagram below.If we now have four microservices, which are users, orders, payments, and collection microservices, they are invoked using HTTP, restful, thrift, Kafka, respectively. This time if we call the client directly in the sense is not too much effort, the client needs to maintain these methods of invocation of the client, if the late addition of micro-services or reduce or replace the call mode, etc., need to modify the client. So let's see what it'

In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la
