Elasto is a cloud library and client utility for managing and manipulating cloud storage objects via REST.

Functionality was recently added to istgt so that it can expose an Azure storage blob for access via iSCSI, it does so using Elasto's file API.

Elasto's file API should be extended, so that it supports Amazon S3 object IO. This task would be difficult, as the S3 REST API does not currently support length@offset writes to objects.

Once complete, istgt could be extended to pass through Amazon S3 credentials to Elasto, and thus expose an iSCSI target backed by an S3 object. This would allow for cloud redundancy / failover by layers above (RAID, etc.).

Looking for hackers with the skills:

      I think, S3 is not designed for this. It is more like a filesystem, where keys are pathnames and values are file content. Is there an API for access to Amazon's Elastic Block Storage (EBS) ? What about owncloud?

      ceph/rbd (used for volumes) and swift (S3 equivalent) from SUSE Cloud would also be a worthy target.

      Indeed, S3's REST interface is not designed for this. Nevertheless, I'd still like to implement it, as this would allow for transparent encryption and compression on the client using existing tools such as dm-crypt and Btrfs. Failover and redundancy between Azure and Amazon S3 storage should also be possible. Amazon already offer a Storage Gateway with a similar purpose, but this promotes vendor lock-in.

      Ceph's RADOS gateway purportedly offers the same REST protocol as Amazon S3. I agree that it and swift would both be worthy targets.
