Cloud paradigm facilitates cost-efficient elastic computing allowing scaling workloads on demand. As cloud size increases, the probability that all workloads simultaneously scale up to their maximum demand, diminishes. This observation allows multiplexing cloud resources among multiple workloads, greatly improving resource utilization. The ability to host virtualized workloads such that available physical capacity is smaller than the sum of maximal demands of the workloads, is referred to as over-commit or over-subscription. © 2012 IFIP.
