This IDC study provides an aggregated worldwide forecast for spending on cloud IT infrastructure hardware (server, storage systems, and network devices across public and private clouds as well as traditional IT environments). It also assesses the impact of cloud (public and hosted private) on the location (on-premise versus off-premise) and ownership of IT Infrastructure in the next five years. For detailed information on spending for each segment (server, storage, and network) and within each region, refer to IDC's Worldwide Quarterly Cloud IT Infrastructure Tracker and Forecast data set with double counting of storage for internal server storage removed.
"Today, companies buy 2.9 times as much IT infrastructure hardware as they 'rent' via IaaS and hosted private cloud services, but in 2019, they will be spending as much to 'rent' IT infrastructure as they'll spend on hardware in their own datacenters." — Richard Villars, vice president, Datacenter and Cloud
