Microservice Traffic Management

For monolithic applications, there is only inbound and outbound traffic. For microservice architecture, there is another traffic from service-to-service invocation. In a complex network topology consisting of many services, traffic is far more complex than that of a monolithic application. Without policies to manage traffic, the behavior and state of the application will be uncontrollable. Traffic control allows us to gain insight into the system state and implement service governance capabilities, such as service discovery, dynamic routing, traffic shifting, etc.
