Kite is a framework that is developed by the team responsible for Koding, the browser-based IDE. The framework is used by the Koding team and was open sourced, since they believed that it would be useful for other microservice practitioners, having faced many of the problems themselves.
The concept behind the framework is that everything is a kite, both servers and clients, and that they communicate in a bi-directional manner using web sockets and an RPC-based protocol. Web sockets make inter-service communication incredibly efficient, as it removes the overhead of constantly having to handshake a connection that can take as much time as the message passing itself. Kite also has a built-in service discovery feature that allows you to make a call to a Kite without knowing the specific endpoint.
