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.

- umur 3y agoRight 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.
- fdr 3y agoI 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 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.
