My father was a small business man.  At 6’2” and 250 lbs., he was a large small business man.  After learning the ropes of North American retail business at Sears for 13 years, he opened up a (literally speaking) Mom and Pop appliance store serving a rural community, where he thrived by nature of his shrewd business acumen and competitive margins.  He also recognized the value of technology tools early on.  It was rare to see him without his trusty HP-12C business calculator using reverse Polish logic.

Recently, the PCI Security Standards Council published an information supplement called PCI DSS Virtualization Guidelines. After having read through it, I would summarize the document thusly:  Treat your virtually-stored information in the same manner you would your physically-stored information. After all, the threats are the same, and the value of the information hasn’t diminished in that the storage medium has changed.  Enterprise level businesses were among the first to see the benefits of reallocating underutilized servers as well as reap the cost saving benefits associated with a smaller server farm footprint, the associated power consumption reduction and physical security requirements.  But as Gartner reports in this eWeek article, >50% of SMBs are forecasted to jump on the virtualization bandwagon by the end of 2012.

I’ll wager that Dad would have been one of the virtualization early adopters.
