According to data compiled by the research firm IDC, the global revenue for servers deployed in public and private clouds is expected to approach $9.4 billion by 2015. This revenue will mainly be driven by IT managers’ growing view of cloud computing as a the best way to simplify managing and administrating of technology environments.

The split in revenue between public and private cloud server is projected at $3.6 billion and $5.8 billion by 2015.

IDC estimates that the number of servers shipped for deployment in public clouds will have a compound annual growth rate (CAGR) of 21 percent for the trailing five years and will exceed 1.2 million by 2015 and about 570,000 servers will be shipped for deployment into private clouds by 2015 for a five-year CAGR of 22.4 percent.

Katie Broderick, IDC senior research analyst said “Cloud computing can dramatically simplify administrating and managing many companies’ data centers and position IT as a service organization for the rest of the company.”

“Off-loading some of the more mundane tasks to the cloud (public or private) and freeing up manpower to focus on adding value to the business is critical to driving cloud adoption.”
