Cloud computing is generating enormous amounts of discussion and excitement in the world of corporate IT. Eager to drive efficiency up and costs down, organizations of every size and description are rapidly adopting Web-based software, platform and infrastructure solutions. Indeed, analyst firm International Data Corporation expects global spending by enterprises on cloud services to rise at a compound annual growth rate of 26 percent between 2009 and 2013, from $17.4 billion to $44.2 billion. Within a matter of years, experts predict, most businesses will utilize at least some cloud-based applications and services. Yet for all its capacity to streamline management and boost agility, cloud computing poses unique power, cooling and availability challenges as well. To meet them, businesses must increase the strength and resiliency of both their electrical and mechanical infrastructures.
This white paper examines some of the forces behind rising adoption of cloud-based solutions, explores how cloud architectures impact data centers and discusses a series of concrete practices and technologies that can help companies collect the benefits of cloud computing without compromising uptime or overwhelming their power and cooling systems.
