As of year-end 2016, off-premises datacenters (MTDC & cloud) account for one-third of total datacenter space in North America. While enterprise-owned datacenters continue to account for the majority (66.8%) of total datacenter space, this growing share of off-premises sites indicates that growth of MTDC and cloud datacenters will come at the expense of on-premises infrastructure. By year-end 2020, the share of enterprise-owned datacenters will decline to 57.5%, while cloud-owned datacenter space is expected to surpass MTDC, accounting for 21.7% of the total.
Digital Realty Trust remains the leader among MTDC-owned datacenters in terms of net operational square footage. At year-end 2016, Digital Realty accounted for 14% of the North American MTDC market, followed by Equinix (5.4% share) and CyrusOne (3.6%).
Updated twice a year, 451 Research's Datacenter Monitor provides a historical and projected installed-base view of enterprise, cloud and MTDC datacenters split by region, company size and datacenter type in terms of facilities count, space, racks and UPS power.
