To be fair, most networked filesystems are nowhere near as good as EBS. That’s one AWS service that takes real work to replicate on-prem.
OTOH, as noted, EBS does not perform as well as native NVMe and is hilariously expensive if you try. And quite a few use cases are just fine on plain old NVMe.
Thats because EBS is a network block device and not a network filesystem - that would be EFS. And with network block devices you get the same perf and better compared to EBS.
