When I read the 5 rules, 4 rules looked like good ones for data centers.
Rule one: Be adaptable and flexible
Rule two: Be easy to fly (operate and use)
Rule three: Be resilient
Rule four – Be easy to maintain (YES!!!!!)
Rule five – Be easy on the eye
The fifth rule "Be easy on the eye" may seem like it doesn't fit, but some of the best data centers are good looking in the details. Some of the worse are kind of ugly and causes discomfort looking at.
