Service Discovery Flow

Mircoservice Architecture

repl mircoservice

The microservice repl replicates the official images from docker hub to your enterprise private registry to keep images fetch traffic on local network.

sche mircoservice

The microservice sche will be scheduled to discover repl services registed in global service discovery server. Once the services are found, it will execute them with additional load balance and routing algorithms.
