Green-as-a-service (GaaS) for cloud service provision operation

Abstract

We introduce the concept of green-as-a-service that provides a cost-effective and specialized on-demand monitoring, analysis, and continuous feeds for energy use and savings which can be exploited by both providers and consumers to meet energy targets. We describe a decentralized architecture model for implementing GaaS and discuss its constituent components. The architecture leverages on SOA and publish-subscribe model to provide an effective solution for wider adoption of the vision and to render an inherently scalable solution. The service has the promise to provide transparency in the way energy and long-term sustainability are linked to the business objectives along with its cost and revenues.
