An article by Ryan Huang, editor at ZDNet's Asia/Singapore office, talks about recognizing vulnerabilities in existing facilities before embarking on a cloud computing deployment for potential adopters to fortify critical systems. The implementation of high-density configuration increases both the compute capacity and energy efficiency of an existing facility. When evaluating external cloud providers, the vendor's data center power infrastructure and availability strategy should also be examined and understood. To create an optimal cloud computing environment, data centers need to bridge the gap between the physical layer of the data center infrastructure and the IT infrastructure.
