This IDC study provides a top-down sizing of worldwide server, power and cooling, and management and administration spending, historically for 1996–2013 and forecast for 2014–2018. These forecasts include dimensions for server hardware, rates of virtualization, and total virtual machines or instance counts. IDC then applies system administration ratios to the physical and virtual server along with power and cooling costs associated with the physical servers deployed in server rooms and datacenters worldwide. The research also considers the impact of servers deployed in hyperscale environments where aggressive standardization often results in much better operational economics than what is generally seen in traditional enterprise datacenters and small IT sites.
Virtual machines (VMs) already far outnumber physical servers, and this disparity is expected to increase significantly in the years ahead. This trend continues to impact the shape of spending in the datacenter as virtualization adoption continues to outpace the use of automation tools and technologies as end users continue to largely manage their server infrastructures in the era of virtualization in much the same way that these infrastructures were managed during the era of physical servers 10 or more years ago. This server, power and cooling, and management and administration spending forecast is the result of work conducted by IDC across several research areas including server and virtualization trackers as well as other primary research.
"There is no doubt that virtualization has had a critical impact on enterprise IT over the past decade. However, as we progress deeper into the virtualization — and cloud — era, IT organizations will need to carefully review their internal processes and consider much deeper adoption of automation tools. Those that do not run the risk of being left behind in the marketplace." — Matt Eastwood, group vice president and general manager, Enterprise Platforms Research
