• gateway

  A Spring Gateway based application which reverse proxy all requests to user-service application.

• user-service

  A backend Spring Boot web application based on tomcat webserver which provides some APIs for external applications.

• user-client

  A client application that calls the APIs provided by user-service via gateway.

• account-client

  A gRPC client application that periodically send request to gRPC server which is hosted by account-service.

• account-service

  A gRPC server application that calls API implemented by user-service to simulate a complicated server call.
