Cloud providers can meet their SLA commitments and manage the energy consumption at the same time Rising global dependence on applications and services challenges cloud providers to meet the need for high availability and fulfill service-level agreement (SLA) requirements. The conventional approach to maintaining high availability is based on accommodating peak traffic loads around the clock, even during long periods of time that require fewer resources. Virtualized data centers offer significant advantages, such as enhanced scalability and elimination of physical management. However, this distributed model results in high energy costs. According to the USA Natural Resources Defense Council, data centers are one of the largest and fastest-growing consumers of electricity in the United States. In 2013, U.S. data centers alone consumed 91 billion KWh of electricity, an amount equivalent to powering all New York households twice over.
