I've been in projects where they're 'on the cloud' to be 'scalable', but I had to estimate my CPU needs up front for a year to get that in the budget, and there wasn't any defined process for "hey, we're growing more than we assumed - we need a second server - or more space - or faster CPUs - etc". Everything that 'cloud' is supposed to allow for - but ... that's not budgeted for - we'll need to have days of meetings to determine where the money for this 'upgrade' is coming from. But our meetings are interrupted by notices from teams that "things are really slow/broken"...
