Yeah in our last year at my previous company, we spent over ~$400k on what amounted to about ~512GB of memory across our fleet of 8 instances on a PaaS vendor. We were almost always memory bound, so I don't even know the compute side.

Given that the hardware itself now costs less than 8k to purchase outright, just seemed ridiculous. Albeit we did have SOC2, enterprise plan, etc, but it was a painful bill every quarter.
