CyberLiveApp: a secure sharing and migration approach for live virtual desktop applications in a cloud environment

In recent years we have witnessed the rapid advent of cloud computing, in which the remote software is delivered as a service and accessed by users using a thin client over the Internet. In particular, the traditional desktop application can execute in the remote virtual machines without re-architecture providing a personal desktop experience to users through remote display technologies. However, existing cloud desktop applications mainly achieve isolation environments using virtual machines (VMs), which cannot adequately support application-oriented collaborations between multiple users and VMs. In this paper, we propose a flexible collaboration approach, named CyberLiveApp, to enable live virtual desktop applications sharing based on a cloud and virtualization infrastructure. The CyberLiveApp supports secure application sharing and on-demand migration among multiple users or equipment. To support VM desktop sharing among multiple users, a secure access mechanism is developed to distinguish view privileges allowing window operation events to be tracked to compute hidden window areas in real time. A proxy-based window filtering mechanism is also proposed to deliver desktops to different users. To support application sharing and migration between VMs, we use the presentation streaming redirection mechanism and VM cloning service. These approaches have been preliminary evaluated on an extended MetaVNC. Results of evaluations have verified that these approaches are effective and useful

TEACHING IN THE CLOUD MICROELECTRONICS UBIQUITOUS LAB (MULAB)

CAD laboratory students activity is mandatory for microelectronics teaching. This, applied in the deep-submicron era, creates new challenges to couple software management simplicity to user friendliness inside lab sessions, which requires the use of complex tools and concepts. In this paper, a new approach to microelectronics CAD deployment is presented, based on virtualization capabilities of new servers hardware and software technology. A test case, realized at Politecnico di Torino, degree of Electronic Engineering, is presented, with real world results on resource consumption and user satisfactio
