Mobile communication networks alone today consume 0.5% of the global energy supply. Meeting the rapidly increasing demand for more capacity in wireless broadband access will further increase the energy consumption. Operators are now... more

Internet traffic has become vast in terms of data processing as well as storage which has occurred some limitations on existing traditional infrastructure. Such limitations may include servers, data storage, and computing resources. This has consequently led most of organization to keep investing and expanding their infrastructure in periodical phases. Hence, two factors are always co-related to each other which are TCO (total cost of ownership) and ROT (return on investment) which are critically increased due to the amount of general investment including all expenses as well as human powers. Therefore, a new technology has emerged which is called “Cloud Computing”. This terminology has been released recently to work as a supportive to traditional infrastructure which is part of Datacenters. It offers reliability, improved QoS, and efficiency to end-users. This paper presents a novel case study of cloud computing on a large scale
environment. Various factors such as TOC and ROI have been taken in consideration on a comparative study with traditional Datacenter. Results have shown considerable improvement on performance, utilization, and investment.

"In its third round of tariff review, the Brazilian Electricity Regulatory Agency (Aneel) adopted a methodology based
on data envelopment analysis (DEA) to define efficient levels of operational expenditure. This work presents proposals
to improve Aneel’s methodology. In particular, we propose the segmentation of the set of distribution utilities using
cluster analysis techniques to establish fair comparisons between utilities. Additionally, we propose a cross evaluation
model using the definition of efficient operational expenditure levels to achieve an efficiency index that accounts
for peer evaluations"
