Total spending on IT infrastructure products for deployment in cloud environments will increase by 24,6% in 2015 to reach $32,8-billion. This amount includes spending on servers, storage (excluding double counting between storage and server), and Ethernet switch products.
According to the International Data Corporation (IDC) Worldwide Quarterly Cloud IT Infrastructure Tracker, spending on cloud IT infrastructure will grow from 28% of overall spending on enterprise IT infrastructure in 2014 to 32,9% in 2015.
In comparison, spending on IT infrastructure deployed in traditional, non-cloud, environments will decline -1,1% in 2015. At $67-billion it will remain the largest segment of the market.
Spending on private cloud IT infrastructure will grow by 19,1% year over year to $12,4-billion, while spending on public cloud IT infrastructure will increase 28,2% year over year in 2015 to $20,4-billion.
Central and Eastern Europe remains the only region where spending on cloud IT infrastructure is expected to decline in 2015. In most other regions, spending on cloud IT infrastructure will grow at double-digit rates. For all three technologies – server, storage and Ethernet switch – growth in spending will exceed 20%; spending on servers will grow at the highest rate, 26,7%.
For the five-year forecast period, IDC expects that spending on IT infrastructure for cloud environments will grow at a compound annual growth rate (CAGR) of 15,5% and will reach $54,3-billion by 2019, accounting for 46,6% of the total spending on enterprise IT infrastructure.
Spending on non-cloud IT infrastructure will decline at a -1,7% CAGR during the same period. Within the cloud segment, spending on public and private cloud IT infrastructure will grow at 16,6% and 13,8% CAGRs respectively. In 2019, IDC expects service providers will spend $34,4-billion on IT infrastructure for delivering public cloud services, while spending on private cloud IT infrastructure will reach $19,9-billion.
“The growing sophistication and reliability of cloud services continue to drive increasing demand for public and private cloud offerings,” says Yezhkova, research director: storage systems at IDC. “End users find that through utilisation of multiple deployment models, including public cloud, on-premises and off-premises private cloud, and traditional IT infrastructure, they can achieve flexibility and agility tuned to the requirements of various legacy and next-gen workloads and applications.”
