Oh, for sure. A lot of startups don't need that ability. I work for a pretty infra heavy startup so AWS is simply required at this point. But we've hit AWS capacity limits during the worst times (one of our clusters processing 20k events/sec hit 100% utilization) and they literally had no capacity left for that instance type. It's not a perfect thing all the time.

But in the end, the pros significantly outweigh the cons. Our resource consumption is naturally extremely elastic. While we'll always need to slightly over-provision to maintain some headroom, adding/removing nodes throughout the variance saves quite a bit of $.
