To the HDS responder - thanks for the update and congratulations on adding V4SIG support. Your claim to have had it for "some time" seems a little strong, as according to Chris Mellors recent post you had it late October - 3 months before this article.
What about the other three features I mentioned? Do you fully support S3 for each of these? Cloudian guarantees 100% S3 compatibility: it's the native interface for Cloudian HyperStore object storage.
Various vendors are claiming support for one or more of the S3 features. It's good they are slowly improving their support, because it’s really, really important and they need to get it right. S3 is the de facto standard for object storage and so to ensure compatibility with all the S3 apps you need full support. You don’t buy NFS that is 60% compliant, so why would you buy a solution that is 60% S3 compliant?
We challenge any vendor to come forward and let an independent analyst test our respective S3 APIs for compatibility with the spec. Happy to work with all vendors on this. S3 is the
standard after all.
