DESCRIPTION
Virtualization technologies have grown very popular in recent years and have proven to be both cost-effective and flexible alternatives to many physical hardware use-cases. ITS is endeavoring to make a compelling virtualization service available to the campus community, and has established a working group to get this initiative off the ground. This presentation will provide a general overview of the technology and its applicability and advantages, a presentation about the service as it exists today, and a précis of the working group’s progress to date. As the main goal of this session is to get feedback from the CTC on the working group’s efforts and any other data that would help inform discussions going forward, a significant amount of time will be devoted to exchanging ideas with attendees.
