Global cloud infrastructure spending (covers servers, disk storage and ethernet switches) is set to grow by 21% to $32 billion in 2015 IDC reports, accounting for 33% of all 2015 IT infrastructure spending.
A chief driver for 2015 is public cloud spending, which is set to grow by 25% to reach $21bn. Meanwhile private cloud infrastructure spending should reach $12bn with 16% growth.
Interestingly W. Europe should see the highest cloud infrastructure growth (32%), followed by Latin America (23%), Japan (22%) and the US (21%).
"The pace of adoption of cloud-based platforms will not abate for quite some time, resulting in cloud IT infrastructure expansion continuing to outpace the growth of the overall IT infrastructure market for the foreseeable future," the analyst says. "As the market evolves into deploying 3rd Platform solutions and developing next-gen software, organizations of all types and sizes will discover that traditional approaches to IT management will increasingly fall short of the simplicity, flexibility, and extensibility requirements that form the core of cloud solutions."
IDC also has a 5-year forecast-- cloud infrastructure spending should grow at a CAGR of 14%, with both public and private cloud spending expected to grow at the same CAGR. Thus, cloud infrastructure spending is forecast to reach $52bn (45% of total IT infrastructure spending), with public cloud representing $32bn and private cloud the remaining $20bn.
