Cloud computing makes diverse applications available anywhere, anytime. It differs from grid computing because whereas a grid consists of a large number of connected compute resources dedicated to a single function, a cloud infrastructure is a dynamic compute resource which delivers a hugely diverse set of applications and functionality. IBM says that means building data centers at a massive scale. Big is better and cheaper. Not so says Microsoft in a white paper, big mega scale data centers bring big problems in everything from construction cost to power. While the argument progresses the infrastructure, hardware and software suppliers are already pushing frameworks, management, monitoring and provisioning products and services into cloud data centers. Applications that are hosted in the cloud require massively scalable data centers to be able to deliver the always-on availability and performance required. It means the compute resources of these data centers must operate at huge scales if the cost benefi ts to the user are to be realised. This is the word according to IBM and its paper "From Cloud Computing to the New Enterprise Data Center." That IBM is building cloud data centers across the world from North Carolina to Shanghai is well publicised. There have been several big investment announcements already in 2008 each involving hundreds of millions of dollars. IBM is also bringing medium scale data centers to support cloud applications. What we know for now is that it is primarily opting for the large scale mega data centers in which infrastructure will be shared.
