When was the last time you had one of those “I wish I knew about that <time period> ago” moments? One of mine was when I saw MAAS (Metal as a Service). Back at the University, as a member of the MADgIK lab, I had to administer a couple of racks. These were the days of Xen paravirtualization, Eucaliptus and the GRID. Interesting times, but I now realise that if I had MAAS and Juju back then, I would have finished with that adventure a couple of years sooner!
