Traffic-Aware Resource Provisioning for Distributed Clouds

Cloud computing´s aim is to provide prompt, reliable, diverse, and yet cost-effective Internet services. To achieve this goal, existing work has considered traffic-aware resource provisioning to reduce cloud energy costs. However, much room remains for achieving a fine-grained traffic-awareness. In this article, the authors examine important cloud traffic characteristics and discuss optimization solutions to reduce energy costs while maintaining service quality. Their solution improves traffic-awareness and efficiently reduces energy costs for distributed clouds with dynamic and diverse traffic.
