IT Cloud Services Spending to Reach $72.9 Billion in 2015: IDC Report
In 2015, public cloud services will account for 46 percent of net new growth in overall IT spending.Cloud computing will continue to reshape the IT landscape over the next five years as spending on public IT cloud services expands at a compound annual growth rate (CAGR) of 27.6 percent from $21.5 billion in 2010 to $72.9 billion in 2015. But the impact of cloud services will extend well beyond IT spending, according to research from IT analytics firm IDC. Cloud services are a critical component in a much larger transformation that IDC expects will drive IT industry growth for the next 25 years, the report said. In 2015, public cloud services will account for 46 percent of net new growth in overall IT spending in five key product categories - applications, application development and deployment, systems infrastructure software, basic storage, and servers, according to the report.
Software-oriented cloud services (SaaS) will account for roughly three quarters of all spending on public cloud IT services throughout the forecast. This includes all three software-oriented cloud categories, not just applications. Spending on hardware-oriented cloud services (servers and storage) will be largely driven by SaaS providers building out their infrastructure.
IDC defines public IT cloud services as those offerings designed for, and commercially offered to, a largely unrestricted marketplace of potential users. The forecast does not include revenue from private cloud deployments, which are dedicated to a specific customer. While private clouds provide the customer with the ability to specify access limitations and the level of resource dedication beyond what is currently available in public cloud offerings, IDC's expectation is that public clouds will mature and eventually incorporate many of the capabilities (particularly security and availability) that make private clouds a more attractive option today.
