A Journey from Virtual Infrastructure to Green Cloud Computing

Abstract

In a cloud value chain, the major goal is to share the resources and services among the cloud partners, cloud vendors and the cloud service consumers which have to be enhanced. Recently the IT industry is growing rapidly to imbibe the concept of “Green”. Apart from considering the cost perspective, it is concerned about making our earth a better to live by reducing waste and non-toxic materials. The power efficiency can be maintained by utilizing technologies like virtualization. Virtualization of data center components which make use of techniques like virtual provisioning, deduplication, virtual machine migration etc., has enriched the load balancing and recovery of servers on data centers. This paper presents an overview of the enabling technologies like virtualization and green computing that paved thewayfor the emergence “Green cloud computing”.
