1. register some metrics exposed to prometheus and these metrics also includes frontend metrics
2. socket io.on listens the event comming from the frontend service via socket.emit
3. signalhandler deals with the signaling process of the pair of sender and receiver

more to-do-lists in the future:

1. overcome the issues of the socket io connection on k8s environment by using ingress
2. deploy on the public cloud
