In the early industrial age businesses used to run their own boilers on their sites to produce steam to drive systems of pulley belts to drive machinery. The companies used to have teams of boiler house men, fitters and engineers to support that power infrastructure.

We are likely to see the same in businesses across the globe as they realise they do not need to retain IT staff to support the basic office function computing.
