Scheduling Virtual Machines in a SaaS environment
Abstract: Given the costs associated with cloud infrastructure, dynamic scheduling of virtual machines (VMs) can significantly lower costs while providing an acceptable service level. We describe a series of forecasting models for predicting the required number of VMs of a cloud-based software used as a SaaS,. These models are incorporated in a periodic-review provision model which determines how many VMs should be provisioned or de-provisioned in the next inspection interval. A simple provisioning heuristic model is also proposed, whereby a fixed reserve capacity of VMs is continuously maintained. We evaluate and compare the performance of these models using simulation and Markovian analysis for different model parameters, using historical data from the Virtual Computing Laboratory (VCL) at North Carolina State University.

The Cloud for Reproducible Research
Abstract:In recent years, the scientific research community has been pushing hard to address issues related to reproducibility of published research findings and results—as the consequences of research misconduct and irreproducibility have been proven to be extremely detrimental, damaging, and even life threatening. This resulted in forming a world-wide movement comprised of many renowned academics and researchers to promote research reproducibility and replication. In this talk, we will discuss and demonstrate how emerging cloud services and technologies can easily facilitate, support, and more importantly, accelerate reproducibility of scientific computation and research—thereby, enhancing transparency, credibility, and increasing the number of citations of research output. The talk will also highlight how leading scientific publishers and research funding agencies are addressing reproducibility. The talk is intended for a general audience.

Participatory Internet: The elementory stone for smart things and smart cities
Abstrat: Things and citizens become smarter when they are fully connected. To connect billions of things and people, network infrastructure and clouds should scale on the same tendency than the volume of traffic and the number of connected devices. Participatory Internet is the key stone for such a scale. It offers the possibility to human and objects to densify the Internet infrastructure at a very low cost. Local cloud and smart edge provided by participatory Internet will offer the optimum solution to connect everything. The keynote will introduce the Participatory Internet with applications for smart citizen and smart things.
