Provide sentiment analysis for each chat
Performance Requirements:
Simultaneous connect with multiple users and send and receive multiple messages
Able to scale automatically without worry about setting up servers to maintain connections
Assumptions:
Assuming each users do not get to see the messages sent before they join
