> I haven't looked into it, but I wouldn't be surprised if they could get around the trickiest constraint, which is how many hard drives you can plug in to a non-mainframe machine for historical image storage.

Netapp is at something > 300TB storage per node IIRC, but in any case it would make more sense to use some cloud service. AWS EFS and S3 don't have any (practically reachable) limit in size.

Have you actually used EFS/S3 before ?

Because both are ridiculously slow to the point where they would be completely unusable for a service such as Twitter whose current latency is based off everything largely being in memory.

And Twitter already evaluated using the cloud for their core services and it was cost-prohibitive compared to on-premise.

EFS indeed sometimes has latency issues I've never been able to track down, but S3 with Cloudfront? That is more than enough as a CDN.
