V-Bundle: Flexible Group Resource Offerings in Clouds

Free registration required

Executive Summary

Traditional Infrastructure-as-a-Service offerings provide customers with large numbers of fixed-size Virtual Machine (VM) instances with resource allocations that are designed to meet application demands. With application demands varying over time, cloud providers gain efficiencies through resource consolidation and over-commitment. For cloud customers, however, this leads to inefficient use of the cloud resources they have purchased. To address cloud customers' dynamic application requirements, the authors present a new cloud resource offering, called v-Bundle, which makes flexible the exchange of resource capacity among multiple VM instances belonging to the same customer.
