Colocation centre

A colocation centre (also spelled co-location, or colo) is a type of data centre where equipment, space, and bandwidth are available for rental to retail customers. They are sometimes also referred to as "carrier hotels." Colocation facilities provide space, power, cooling, and physical security for the server, storage, and networking equipment of other firms—and connect them to a variety of telecommunications and network service providers—with a minimum of cost and complexity.
