Modern science presents a number of challenges to the cyber-infrastructure supporting it: heterogeneity of the required computational resources, problems associated with storing, preserving and moving large quantities of information, a collaborative nature of scientific activities requiring shared access to resources, continuously growing requirements for computational power and network bandwidth,...
This paper presents the concept of Open Cloud eXchange (OCX) that has been proposed to bridge the gap between two major components of the cloud services provisioning infrastructure: Cloud Service Provider (CSP) infrastructure, and cloud services delivery infrastructure which in many cases requires dedicated local infrastructure and quality of services that cannot be delivered by the public Internet...
Modernizing experimentation in system-oriented courses such as computer networks and distributed systems is often challenging due to the raw and complex nature of infrastructure testing. In these practical courses, students not only need access to network layers and system kernels, but they often need to reason about consistency issues associated with the distributed nature of these experiments. This...
