@cstross With great computing power comes huge bills.

Bad design using lambdas at cloud scale can bankrupt your corp doing mundane processing, badly.

Been there, seen that. Tried to get the team not to do it. Oh well, so sad, "velocity" and "time to market".

What cloud permits is to see the consequences of terrible design in the bottom line, very very quickly.

It used to be that terrible design slowed you down. We have now traded slowing velocity for hugely increasing cloud bills.
