I'll be teaching a class based on this article in Fri, March 23 2012 at the Cascadia IT Conference in Seattle, WA and on Fri, May 11, 2012 at the LOPSA PICC 2012 Conference in New Brunswick, NJ. Seating is limited. Register soon!
I'll also be teaching my Time Management class and giving an invited talk on the Ganeti virtual server cluster management software.
See you there!
