I recently found this article which discusses the rationale for cloud adoption: http://www.tmcnet.com/usubmit/2011/10/31/5893685.htm. One factor listed is capacity management - "Users are considering cloud for capacity
management issues including periodic demand peaks and better management
of data center growth, power, and cooling issues." This statement speaks to the maturity of clients surveyed who are considering cloud in that they have the visibility into their virtual environment to understand workload usage trends such as predicting peaks and projecting growth of data center resource consumption. In other words, before clients can leverage cloud for adding capacity for periodic demanding peaks, they first must have capabilities in place for visibility of existing infrastructure. I am curious to understand if any of those surveyed have optimized their virtual environment; meaning, have they rightsized their workloads and placed workloads in a way to maximize available capacity.
