The idea of this project was to create a simple chat application that would grow over time. As a result, there would be more and more clients that want to chat with each other, what might lead to problems in the server that have to be fixed. Which exact problems will occur, we were going to see along the project.

In the center is a simple chat server that broadcasts incoming messages to all clients. In order to notify the clients about new messages, the connection should be static and bidirectional. Therefore, we based the communication on the WebSocket protocol.

Furthermore, wanted to see how the server behaves with the rising load. Therefore, we had the plan of performing several load tests to display the weak points and improvements, as the system enhances.
