Title: Time delay and its effect in a virtual lab created using cloud computing
Author: Nunez, Juan
Abstract: The emergence of Cloud Computing, as a model of virtualized physical resources and virtualized infrastructure, offers the opportunity of outsourcing the implementation of a Virtual Lab Manager. Virtual Lab Management has come to be considered the Holy Grail in the deployment and administration of Labs created in a Virtual Environment. With the advent of Cloud Computing new opportunities are developing that promise to cover much of the future in Virtual Labs. Designing network and information labs with real equipment and tools does not make sense from a cost benefit standpoint, as hardware gets obsolete in a short gap of time, therefore replacing real labs with labs in a Virtual environment this days is a must for teaching in information, security and network classes. Choosing an adequate Virtual Lab Environment solves the problem of creating an adequate academic environment where teachers can serve as effective guides for students which will have a lot of freedom and first hand on experience in the learning subject under consideration. A Virtual Lab Manager in a Cloud Computing environment reduces cost even further, but creates some doubts about the time delays inherent in such a technology. After choosing to use the one created by VMLogix for Amazonaws ec2, it was decided to answer a question in this paper: being Virtual Labs a real time application, how it is affected by time delays and bandwidth when accessed from remote places? The same criteria used for video on demand, voice-over-IP or on line business system as used in networks are going to be applied in the presented work although the much interactivity in a Virtual Lab of any kind.
