Hey this is Brian -- I wrote the article. I have heard the term a lot over the years. I think you could call it that -- the idea being its the "foggy" area between the user and the cloud. The reason we like "micro private cloud" is that 1) its a tiny environment with limited cloud properties (no elastic scale) but 2) we do try and provide a platform with cloud-like services for our internal developers, and we like the cloud paradigms being applied to how we think about compute at the edge, in restaurants.
