This project is for a course CSE811 in Ajou Univ. The application is basically a client-server model but it has different server nodes for better fault tolerance and to distribute client traffic. Each component is deployed in a docker container except the clients. The server container will be tied in a same network so that each node can communicate with each other.

The detail of implementation will not be explained since the code is pretty much self-explantory.

• Master & Slaves should run first and they need a time to be tied with each other, which means that there must be a time to the slave to send a capacity to the master.
