I havent looked at OVH lately, but are they really a cloud? Do they provide full VPC with central firewall? Dynamic network disk storage that can be mapped to

I havent looked at OVH lately, but are they really a cloud? Do they provide full VPC with central firewall? Dynamic network disk storage that can be mapped to servers?

How does EBS work, anyway? Is it some form of NFS with caching under the hood?

  It's not NFS, it's a block storage mechanism. NFS presents a file-based interface, EBS is a block/device-based interface. The underlying implementation isn't widely publicized, but if you think about how a block device works on a Unix and the AWS bigger-is-faster model for non-PIOPS EBS, you can probably draw some reasonable inferences.

    PIOPS?
    - snuxoll 9y ago
      Provisioned/guaranteed IOPS.

  IIRC EBS is based on GNBD.

    Such rumors have been around for quite a while -- Amazon is not talking -- but their relevant patent https://www.google.com/patents/US8769186 https://www.google.com/patents/US8769186 has > For example, in at least some embodiments, a representative logical local block data storage device may be made available to an executing program via use of GNBD (“Global Network Block Device”) technology.

  EBS is some kind of Network Block Device. NFS is another product, https://aws.amazon.com/efs/ https://aws.amazon.com/efs/

OVH does have their vRack stuff these days, but it's iffy and clearly intended for dedicated hardware. They have no block storage that I'm aware of.

  They do have it: https://www.ovh.com/ca/en/public-cloud/storage/additional-disks/ https://www.ovh.com/ca/en/public-cloud/storage/additional-di... It's OpenStack Cinder. They also have object storage, Swift: https://www.ovh.com/ca/en/public-cloud/storage/object-storage/ https://www.ovh.com/ca/en/public-cloud/storage/object-storag...

    TIL, thanks! Didn't realize OVH was OpenStack--that's a pretty hard no for me, because I've witnessed firsthand the failure conditions there, but I appreciate the correction.
