Energy Conservation Day: Symbolism Doesn’T Pay, Hippu Salk Kristle Nathan

Hippu Salk Kristle Nathan

The much publicised panting competition at school level on the occasion of Energy Conservation Day was a good effort to send message to consumers to influence their energy consumption behaviour. But the effect is minuscule.

As a child one might have walked or cycled to school. But as a breadwinner, once energy related decisions largely get influenced by one's income level and opportunities and restrictions.

Online Virtual Network Provisioning In Distributed Cloud Computing Data Centers, Khaled Mefarh Alhazmi

Electronic Thesis and Dissertation Repository

Efficient virtualization methodologies constitute the core of cloud computing data center implementation. Clients are attracted to the cloud model by the ability to scale available resources dynamically and the flexibility in payment options. However, performance hiccups can push them to return to the buy-and-maintain model. Virtualization plays a key role in the synchronous management of the thousands of servers along with clients' data residing on them. To achieve seamless virtualization, cloud providers require a system that performs the function of virtual network mapping. This includes receiving the cloud client requests and allocating computational and network resources in a way that …

Congestion Control, Energy Efficiency And Virtual Machine Placement For Data Centers, Yan Zhang

Dissertations

Data centers, facilities with communications network equipment and servers for data processing and/or storage, are prevalent and essential to provide a myriad of services and applications for various private, non-profit, and government systems, and they also form the foundation of cloud computing, which is transforming the technological landscape of the Internet. With rapid deployment of modern high-speed low-latency large-scale data centers, many issues have emerged in data centers, such as data center architecture design, congestion control, energy efficiency, virtual machine placement, and load balancing.

The objective of this thesis is multi-fold. First, an enhanced Quantized Congestion Notification (QCN) congestion notification …
