According to IDC’s Worldwide Quarterly Cloud IT Infrastructure tracker, enterprises are on course to spend $32.6bn on cloud-related IT infrastructure in 2015, which is 24% more than in 2014.
This means around a third of enterprise IT spend will be invested in cloud-enabling technologies. The remainder of this sum ($66.8bn) will be used to purchase on-premise servers, storage and Ethernet switches.
Despite this, IDC predicts the amount spent on non-cloud IT infrastructure will fall by 1.6%, as organisations shun on-premise technologies in favour of private and public cloud-enabling kit.
As such, IDC forecasts enterprises will shell out $12.1bn on private cloud infrastructures, equating to a year-on-year rise of 15.8%, and $20.5bn on public cloud technologies, which is 29.6% more than in 2015.
Spending on cloud IT infrastructure is expected to grow across all regions in 2015, with the exception of central and eastern Europe because of the current political and economic instability affecting these areas.
According to IDC’s five-year forecast, cloud infrastructure IT spending is set to grow at a compound annual growth rate (CAGR) of 15.1% and will hit $53.1bn by 2019. By this time, it will also account for nearly half of all enterprise IT spend.
“Numerous IDC surveys indicate growing interest among enterprise customers to cloud deployments across multiple IT domains,” she said.
“Users often cite the agility of IT infrastructure and economic reasons as drivers for cloud adoption, but we also expect the proliferation of next generation applications born and run in the cloud will fuel its further growth.”
