I'm honestly confused why local nvme disks haven't become the standard for cloud offerings a long time ago.

Aiven (not working for them, just a happy client) started offering local nvme disks for their postgres service in 2017. (https://aiven.io/blog/larger-and-faster-aiven-postgresql-pla...)

Back then I was sure it was only a matter of time for other hosted database providers to move on from EBS. But until Planetscale made a lot of noise about Metal no one seemed to bother.
