Usually efficiency is defined in energetic terms without taking into account the quality of the energy. Another way to analyse and optimise processes and systems is in terms of exergy. The concept of exergy incorporates both qualitative and quantitative properties of energy. Exergy analysis makes the exact determination of the energetic and resource saving potential of industrial processes or s...

During recent years, attention in ‘Green Computing’ has moved research into energy-saving techniques for home computers to enterprise systems' Client and Server machines. Saving energy or reduction of carbon footprints is one of the aspects of Green Computing. The research in the direction of Green Computing is more than just saving energy and reducing carbon foot prints. This study provides a ...

A hybrid disk consists of a small amount of NonVolatile flash Memory (NVM) as fast storage media to complement the rotational magnetic recording disk, normally considered slow but with large storage capacity. In this paper, we present the design and development work of an enterprise hybrid disk drive storage system for future datacenter. We also design a new type of dynamic cache algorithms tha...

Cloud computing is maturing, becoming a viable alternative to classic on-premise IT. Cloud facilitates scalability, promising lower fixed and variable costs while supporting enterprise growth. The scalability benefits and cost savings can be achieved through ondemand infrastructure provisioning and reduced on-premise energy consumption. The benefits are compelling; however, a quantitative analy...

The Special Issue of the Journal of Information Technology Management (JITM) is publishing very selective papers on information management, technology in higher education, integrated systems, enterprise management, cultural thoughts, strategic contributions, management information systems, and cloud computing. We received numerous papers for this special issue but after an extensive pe...

The paper focuses on the urgency of the implementation of cloud technologies, which are a necessary condition for the development of enterprise management systems, give rise to a complex of insufficiently studied phenomena and processes and determine the need to find new tools in making and implementing reasonable management decisions. In the process of research, the sequence of construction an...

In enterprise networks, idle desktop machines rarely sleep, because users (and IT departments) want them to be always accessible. While a number of solutions have been proposed, few have been evaluated via real deployments. We have built and deployed a lightweight sleep proxy system at Microsoft Research. Our system has been operational for six months, and has over 50 active users. This paper f...
