Hear, hear. My personal AWS bill is roughly $10/month, all for S3. We're not talking millions here :). Personal compute is a mix of OVH and on-prem. Work is an entirely different kettle of fish, at an entirely different scale, and primarily runs compute on spot: https://aws.amazon.com/blogs/aws/capacity-optimized-spot-instance-allocation-in-action-at-mobileye-and-skyscanner/ https://aws.amazon.com/blogs/aws/capacity-optimized-spot-ins... Being able to scale down, rather than needing to pay for peak capacity, genuinely does save us large amounts of money. But it's a capability that we needed to build out, not something that happened by magic. And it does require that our services are big enough to scale for load, not just for redundancy.
