Recent deployments of FPGAs as compute resources in data centers have raised security concerns. One concern is how to prevent user-deployed logic in the FPGA from accessing privileged data such as physical addresses or raw network traffic. Addressing this issue uses the concept of ‘privileged’ mode FPGA logic that is kept separate from ‘user’ mode logic. Logical separation can be achieved with design...
Cloud computing is based on virtualization, where a single physical resource is virtualized into multiple virtual resources. Processor and network virtualization offer many advantages like saving in hardware cost, energy consumption, human effort and management of resources. In this paper we have evaluated the effect of network and processor virtualization using popular open source tools, Open vSwitch...
This paper presents a comprehensive system architecture, which adopts private cloud computing as the deployment model for consolidating IT services and data centers across different agencies within Taiwan Environmental Protection Administration (EPA). Through a number of well-planned procedures we integrates original 130 servers into 25 servers and merges 9 data centers into 2 data centers. The project...
Information availability is crucial for business continuity and enterprise level service provisioning. Maintaining information flow without compromising Confidentiality, Integrity, and Availability is a major task for the Information Technology Managers. Besides this, the dependability on Information has increased exponentially which requires highly complex Data Centers, which in turn become a huge...
As data center costs rise and space availability diminishes many organizations are investigating the viability of cloud computing for research use. Yet the majority of research investigators have not readily embraced cloud capability, regardless of the potential cost savings. Through interviews, case studies, and up-to-the-minute blog posts from top experts, it is possible to extract a basic framework...
