According to Rakesh Dogra, former engineer and freelance consultant, cloud computing is changing the demographics of the traditional data center by cutting down on wasted resources and maximizing the potential of servers.
Writing for the Data Center Journal, Dogra explains the improved environmental efficiency is possible in large part because virtualization technologies allow data centers to create new devices, such as VPS servers, that are capable of storing more information and can be managed more effectively than standard servers.
According to Dogra, deploying server virtualization architectures allows data centers to reduce their environmental footprint by using less power and requiring fewer resources for cooling and other maintenance procedures. This is possible because virtual systems can contain multiple separate servers in one physical device, reducing the number of physical servers, Dogra said.
Cloud computing fits intuitively with virtualization, Dogra explains, because it can serve as an infrastructural element to deploy cloud computing solutions from.
According to the U.S. Environmental Protection Agency, data centers use 1.5 percent of the nation's electricity. Based on current technologies, that number is expected to double within five years, making sustainable upgrades, such as virtualization, critical for environmental efficiency in coming years.
