# Portal And Server

Evennia consists of two processes, known as Portal and Server. They can be controlled from inside the game or from the command line as described here.

If you are new to the concept, the main purpose of separating the two is to have accounts connect to the Portal but keep the MUD running on the Server. This way one can restart/reload the game (the Server part) without Accounts getting disconnected.

The Server and Portal are glued together via an AMP (Asynchronous Messaging Protocol) connection. This allows the two programs to communicate seamlessly.
