From a client perspective, online video communication is insanely simple today. You do not even need to install anything on your computer to call another person via the Internet. Modern video API solutions often require an Internet connection only to work, which is truly convenient. However, some work must be done behind the scenes to offer software users such an opportunity. Thanks to WebRTC signaling servers, people can engage in peer-to-peer communication right in the browser using video, audio, and data sharing. Whenever you are using a web interface to communicate with someone in real time, this connection happens via WebRTC signaling servers.
