Ubicloud seems very cool, but I wonder what the long term plan for volumes is. Without network attached storage (EBS), running stateful services is tricky.

Right now, we have an early block store (EBS) that is non-replicated, and that we are testing and using internally. Over time, we will expose it as a service as well. But object store (S3) will come first.

I work at Ubicloud.

The general plan is: write a SPDK module. We spent some of the last year getting used to using SPDK, for cryptography and workaday disk access, and the first copy-on-access custom bdev (a unit of abstraction in SPDK) is working its way into production now.

https://github.com/ubicloud/bdev_ubi

This copy-on-access happens to use files as the input, but sometime after that, it will be usable for demand-paging images hosted via HTTPS as well.

Some of those code paths will likely learn flavor(s) of replication after that.
