The cloud always seemed foolish to me. A company's computers and the data they contain are one of its most critical resources. For an IT company it's everything. To put that anywhere other than one's own secured datacenter is crazy. I'm a firm believer in "If you don't hold it, you don't own it." Also: "Two is one, and one is none."

Companies might complain that they can't find the talent to manage all this. Well then they need to hire some bright teenagers and teach them instead of expecting to get the perfect plug and play candidate. Those employees will be more loyal over the long term for a variety of reasons. But the owners don't care about providing for the future, only this quarter's sales.

Companies should invest in their own computing infrastructure even if it costs more, just so they can continue doing business as usual while the rest of the world's hair is on fire about the latest Windows rootkit or Microsoft/Github/AWS outage or whatever.
