SSDs Have Become Fast, Except in the Cloud

Redundancy, local storage is a single point of failure.

You can use local SSD’s as slow RAM, but anything on it can go away at any moment.

I've seen SANs get nuked by operator error or by environmental issues (overheated DC == SAN shuts itself down).

Distributed clusters of things can work just fine on ephemeral local storage (aka local storage). A kafka cluster or an opensearch cluster will be fine using instance local storage, for instance.

As with everything else.... "it depends"

Sure distributed clusters get back to network/workload limitations.

These days it's likely that your SAN is actually just a cluster of commodity hardware where the disks/SSDs have custom firmware and some fancy block shoveling software.
