And all those cloud compute instances are probably strangled for io if there is any real load. Colocating your own equipment is going to give way better base performance. Compute is not just processor and memory, it's also dependent on network and disk i/o. Disk is often overlooked because modern disks are so fast, people don't even realize it's crippled in the cloud.

It really is crippled to an absurd degree. A basic RDS install with a gp3 volume will get 3k IOPS and 0.125 GB/s transfer if your volume is under 400 GB, or 12k IOPS and 0.5 GB/s transfer if it's larger. The monthly per-GB storage cost for RDS is the same as the capital costs to buy the disks in a mirrored setup. Meanwhile, if you bought the disks, you'd get over 100x the IOPS and 10x the transfer.

For a provisioned IOPS volume, you can get up to 256k IOPS (so still a fraction of a single drive) at a cost of $25600/month (plus per-GB storage costs). For that price, you could buy 8x of these: https://www.newegg.com/micron-30-72-tb-9400/p/N82E1682036315... giving you 240 TB of raw SSD storage.
