At VMworld 2011 in Las Vegas, Nevada, more than 6,000 attendees completed 13,000+ labs over the course of four days, driving the creation and destruction of 145,000+ virtual machines. To say the least, it is a significant accomplishment - one that resulted from many iterations of design and years of working to deliver a constantly improving experience to end users. Since 2004, Hands-On Labs (HOLs) have been a part of VMworld. Over the years, HOLs evolved along with VMware's technology portfolio. The goal of HOLs has always been to provide hands-on access to the latest VMware technologies in a manner that straddles the fence between technical marketing and training.
