An honorable practice: Eating your own dogfood
Agree, rradina, Eating your own dog food means you're willing to do yourself as a software user what you urge others to do. The term was popularized by David Cutler as his team developed Windows NT. They were not only going to produce a good operating system, Microsoft was going to use it. Windows Server, in my mind, has met that test. (Cutler also lead development of Digital Equipment's VMS, a great operating system.) In a similar vein, I think Mike Neil is saying that Microsoft not only urges people to use cloud computing but is illustrating that it knows how to build and run cloud infrastructure. The implicit comparison is with VMware, as I remember the conversation. VMware came to its own cloud data centers only recently.
