A colocation data center can provide IT facilities equipment, rack space, connectivity, and environmental support facilities, including power, cooling, physical security, and physical storage. Data center colocation service providers sell (lease) to both the wholesale and retail markets, and these services are typically priced on the rack displacement and the power presentation, in amps or kilowatts per hour.
The majority of colocation consumers choose a service provider based on a number of key attributes including conjunction with a high-speed communication hub, consumer to data center proximity, data center to data center proximity for bandwidth capability, data center tier and service accreditation (for example List X), regional locations or global presence, rather than just cost.
