Total cloud IT infrastructure spending (server, disk storage, and Ethernet switch) grew by 14.4% year over year to $8-billion in the fourth quarter of 2014, accounting for approximately 30% of all IT infrastructure spend, up from about 27% one year ago.

This is according to International Data Corporation’s (IDC) Wordlwide Quarterly Cloud IT Infrastructure Tracker, which also found that private cloud infrastructure spending grew by 18.3% year over year to $2,9-billion, while public cloud infrastructure spending grew to $5-billion, 12.3% higher than one year ago.

For the full year 2014, cloud IT infrastructure spending totaled $26.4-billion, up 18.7% year over year from $22.3-billion; private cloud spending was just under $10-billion, up 20.7% year over year, while public cloud spending was $16.5-billion, up 17.5% year over year.

“The transition to cloud-oriented infrastructure and data platform architectures within enterprises’ data centers continues to accelerate, yet the expansion of public cloud infrastructure in service providers’ data centers around the world is an even larger driver of IT spending,” says Richard Villars, vice-president: data center and cloud research at IDC. “A key driver of this acceleration is organiations’ development and use of new Internet of Things services that require levels of agility and scale that only cloud solutions can deliver.”

For this second quarterly release of Cloud IT market results, IDC has expanded its worldwide coverage to include detail for eight regions: Asia/Pacific (excluding Japan), Canada, Central & Eastern Europe, Japan, Latin America, Middle East & Africa, US, and Western Europe. In 4Q14, the US had the highest share of overall cloud IT infrastructure spending with 64%, followed by Asia/Pacific (excluding Japan) with 17% and Western Europe with 12%. Western Europe had the highest growth in cloud IT infrastructure spending with 30% year over year growth.
