Kjell's Law: the cost of a platform eventually exceeds the cost of the one it replaced. But each cost is in a different budget.

We seem to have replaced cooling and power and a grumpy sysadmin with storage and architects and unhappy developers.

I've never worked in a data center that did cooling and power correctly. Everyone thinks they're doing it right, and then street power gets cut - there's significant impact, ops teams scramble to contain, and finally there's the finger-pointing.

Or the electrician doing maintenance on the backup generator doesn't properly connect the bypass and no one notices until he disconnects the generator and the entire DC instantly goes quiet.

Or your DC provisions rack space without knowing which servers are redundant with which other servers, and suddenly when two services go from 10% CPU use to 100% CPU across ten servers the breaker for that circuit gives up entirely and takes down your entire business.
