Colocation is a term used to describe a certain type of IT Hosting service provided by telecommunication facilities and data centers to clients who own equipment and need to house it. There are different levels of Colocation – from colocation of a single standard desktop computer or rack server to rack enclosures (cabinets) used for colocation of multiple computing appliances.
