Architectural Strategies for Green Cloud Computing: Environments, Infrastructure and Resources

Introduction

Today is the age of information technology. The facets of work and personal life are moving towards the concept of availability of everything online. Significant technological advances are often made during periods of crisis and change. Thus it is unsurprising that today’s CIO’s and IT professionals, confronted with extraordinary challenges of spiking energy bills, underutilized data centers, accelerated data growth, during a time of restricted capital and economic uncertainty are gravitating towards innovative efficiency enhancing technological models (http://www.gartner.com). SYS-CON's Cloud Computing Journal lists the top 150 most active players in the cloud ecosystem (Geelan, 2009). A robust ecosystem of solutions providers is emerging around cloud computing. In this paper we discuss the various feasible applications of the latest Java Enterprise Edition platform and the potential roles of web profiles in the present context along with multi-cloud framework approach. The paper also elucidates cloud databases and suggests on preparing data for cloud within the limits of CAP theorem. The paper highlights the open source private cloud computing benefits mainly of the Eucalyptus. Cloud computing scenario in India in general and for the small and medium enterprises are also discussed. Finally, cloud applications in education and the resources available are explained in detail.
