Since the abstraction is NFS for access, I wonder what the advantage over EFS is. Or more, why not just leverage this under EFS if it was a straight improvement. Compression and snapshots seem like some of the biggest wins over current EFS.

EFS performance is garbage compared to FSx for most things. They serve different purposes.

Compression and snapshots indeed are the largest improvements I see, as well as an order-of-magnitude higher performance. If your applications already rely on ZFS snapshots, filesystems, quotas, reservations, compression, etc. - this is a pretty huge release as it appears to enable a convenient multi-reader workflow without significant administration headaches.

While looking into this new OpenZFS service I noticed that NetApp ONTAP is now also available as 'Amazon FSx for ONTAP' as of Sept. 2021. It costs more than this OpenZFS service, but it offers higher availability and more capabilities (iSCSI block devices, for instance.)

Wow, OpenZFS in the cloud. Corey Quinn just called it the best launch at reInvent! https://twitter.com/QuinnyPig/status/1465834063877443584?s=2...

Sure a shill would say that:

>FSx for OpenZFS is powered by the AWS Graviton family processors and AWS SRD (Scalable Reliable Datagram) Networking,

This is Amazon owning the whole Stack.

The pace of innovation at AWS Scale is insane. And quite scary.

Was super excited at first, but then saw it's NFS access only. I don't see any options to do "zfs send" to ship entire encrypted datasets over.

Right, none of the people that specifically picked ZFS are gonna be in love with this.

It feels to me like there's space for a service that acts like `zfs recv` but backs it with super cheap Backblaze or Glacier storage. Which, I know you can just zfs send to a file, but then restoring a single file is a pain.
