Why Corporate Cloud Storage Doesn't Add Up 141

snydeq writes "Deep End's Paul Venezia sees few business IT situations that could make good use of full cloud storage services, outside of startups. 'As IT continues in a zigzag path of figuring out what to do with this "cloud" stuff, it seems that some companies are getting ahead of themselves. In particular, the concept of outsourcing storage to a cloud provider puzzles me. I can see some benefits in other cloud services (though I still find the trust aspect difficult to reconcile), but full-on cloud storage offerings don't make sense outside of some rare circumstances.'"

    I work for a printing company... cloud storage companies call us all the time with the pitches. Then they ask .. "how much data are you currently backing up?" .. we say "around 38 terabyte's" .. they say .. "no .. we aren't asking what your archives are, we are asking what your daily backups are." we say "we back up once a week. our weekly backups are around 38 terabytes." Then they say "that is a little more than we can handle" so I ask "well what can you handle?" almost every one of them has said they generally look for companies that have between 500GB and 1TB of storage. I guess if you fit that spec, it would work.

    • That sounds like someone with a computer with a couple of external hard drives plugged in using cloud as a buzzword.

      Although I've always been curious how Amazon can offer pricing for 5 petabytes and above.

      • "That sounds like someone with a computer with a couple of external hard drives plugged in using cloud as a buzzword."

        That sound a customer restriction to me. I can own a bazillion petabytes worth of storage but if you are in the other side of a cable modem there's no way you can exchange with me 38TB a week.

      I have the same issue. I work for a small suburban newspaper, and even our hot data set is over 1TB, plus append-only archival data of more than 4TB.

      When I tell these "cloud backup" providers this they do a double-take and then start talking laughably high prices or they just back off and say they can't really handle our archival data set. It's quite pathetic when my 10TB backup storage server in a fire-resistant, water-resistant enclosure in the shed cost under $5k when built - and that was when 10x1TB disks was a lot so the disks cost over $2500 by themselves.

      Because I'm in Australia I also have the issue of bandwidth. I'd need a backup provider to peer with my ISP via a local peering point that offers unmetered traffic; with 100GB/month limits considered very big here I couldn't possibly back up over a metered link. Even then, my redundant two ADSL2+ links achive about 6Mbit/750kbit and 4Mbit/500kbit per second each, so I'd probably need to pay to run fibre from the nearest line along the train line (est $50,000) and pay over $1000/month for a fibre service just to talk to the backup storage host.

      I'm negotiating to move our backup server to a business down the street and run an 802.11n point-to-point directional link between us instead. We each get to fail over to each others' Internet services if necessary, we exchange backup storage, and neither of us gets to pay through the nose for it. It's not as good as a fast link to a DC somewhere, but it's a hell of a lot more practical.

      The other issue with cloud backups arises when you need that 5TB (mine) or 38TB (yours) in a hurry, for disaster recovery. You can't exactly run down the street and grab the server with its disk array then restore over 1Gbit ethernet or direct to locally attached SAS/eSATA/whatever. Nope, you have to download all that data over whatever Internet link you have access to. If that's not the dedicated fast link your premises has (say, if they've burned down) then you are screwed.

      I'll keep my primary backups within driving distance, thanks.

      • A business down the street? As I see it, off-site storage - cloud... whatever - and even hosted servers are fine technologies for disaster recovery. If your block or neighbourhood gets caught up in a big fire, earthquake or flood having your off-site back-up "down the street" might not be as helpful as you hoped. You even acknowledge this.

          Australia has only a couple of big international data links, and they've been known to go down when cables get cut by idiot trawlers. This usually causes severe congestion on the other links and I would NOT want to be running my business off those links when this happens. If you're not in .AU/.NZ, this probably isn't an issue for you, and in .AU or .NZ one can always host with

          What do you mean by "or"? In Australia they have all three at once!

      • Surely the issue is not how much data you have, but how much bandwidth you need.

        You can physically perform the initial transfer, so no problem if it's 1GB or 100TB.

        The question is, do you need to access more of that than the bandwidth can carry?

        If you need to extensively modify all of that data each day, then clearly cloud won't work for you if those modifications require lots of data from outside the cloud data centre.

          LTO-5 drives are now AU$2500 to AU$3000 + SAS HBA, a good year or two after I built that backup server. Most of our data set is data in formats that're already efficiently compressed with JPEG, LZO, PNG, deflate/zlib, etc, there's no significant compression gain; tapes can be presumed to be 1.5TB.

    Ok. Somebody is completely off-their-head nuts, either the author or the people he is writing about(and I have my suspicions about the author...)

    To the best of my knowledge, nobody pitches this 'cloud storage' stuff as a replacement for local storage, unless they are also selling some hosted software-as-a-vendor-lock-in 'solution'. It's a sufficiently overwhelmingly bad idea that nobody even tries. So, what exactly is he wasting an article on?

    Yup, SATA drives are cheap and reasonably zippy. Y'know what's less cheap, more complex, and not as zippy? Good Backups, including offsite. And that, (along with the web hosting and CDN focused stuff) is what the 'cloud' people are selling. No shit delivering files over the internet with a 200ms round-trip and a teeny pipe isn't going to replace the local storage or a network share a couple of GigE hops away. Replace that balky tape library the next time it conks out, though? Not certain; but much more conceivable...

      I don't know if you have been in corporate IT lately but these people selling the crap are indeed selling this as the end-all-be-all of computing. Everything (data storage, web hosting, virtual servers, desktops, crm and similar databasing needs, e-mail, ...) is supposed to be in the cloud at a much lower price point. Microsoft is one of the worst offenders as they sell their entire suite (Exchange, AD, ShitPoint, Office ...) in the "cloud" these days, promise the world but have no way to deliver.

      If you have an IT organization with more than 2 IT people where stuffing the "cloud" (or having everything hosted for you) is going to end up being cheaper you have a really badly managed department that is extremely bloated.

      For enterprise data storage: average price is $1,000/TB/year (Amazon et al) while a decent locally managed system (SAS, HA) should be ~$100-300/TB/year. Off course if you pay NetApp or the like (at ~$3,000/TB/year) for your storage, you brought this upon yourself and the person making that decision should've been fired.

        Don't forget to factor in the cost of the bandwidth to the storage.

    • I suppose if you're a tiny company with a tiny amount of data to backup it'd make sense. If you had even a few tens of gigabytes of data why do you want your offsite storage behind a network connection that can deliver perhaps 1 MB/s? Sure if I want to do an occasional file restore, but when the shit hit the fan I want to be able to bring a crate full of tapes into my data center and streaming off of 8 tape drives at 400 MB/s.

      *nod* I tend to assume that many of the 'cloud' companies are traditional off site backup providers that have done a little rebranding.

      Though such services are also useful for small companies that are not set up to host their own servers and want to move files between far flung people. I think a lot of geeks tend to forget that not every company is interested in having its own servers and IT dept when their buisness has nothing to do with computers.

      Do any of these CIOs run companies that fall under SOX, HIPAA, or PCI? How does your CIO ensure that files stored on the cloud storage meet any of those regulatory requirements? All it takes is one personnel file with medical records to leak into the wild to for the company to face liability under HIPAA for unauthorized release. If the company knowingly allowed sensitive files to be stored in unsecured storage, the penalties could be substantial.

    Why don't people look in the history books of computing. If they did they would see that in the before the 80's everything was in "the cloud", except back then they called it servers. They rented these servers and the storage space from IBM, Digital, HP and a few other server providers. The personal computer came a long and data started shifting on to local hard drives and WIntel or Novell LAN servers.

    Now they have the problem of trying to maintain every spreadsheet and Access DB sitting on a managers laptop. To solve this they are going back to the future and storing stuff back on servers sold to us by young people who never knew what DASD is. Controls and audits will demand restricted access and rules be put in the cloud for protection just like before. After about 10 years we will all be bitching and complaining about the cloud and praising local storage for it's ease of access and not having our data held hostage by providers. Lather, rinse, repeat.

    For me the one attractive use case for cloud storage is for backups - and it's one that's catered to particularly poorly by current offerings.

    For backups, you want (a) fast, unmetered links to the host and (b) moderately reliable, cheap, and not-that-fast storage you can access in a variety of different ways depending on what's most convenient, with or without running your own VPS to mediate between storage and storage clients.

    One user will want to rsync to their cloud storage. One will want to remote-mount a file system on it via iSCSI. Another will want to run a Bacula storage daemon on it. Yet another will want to use it as a co-ordinator for a full network backup system. All these use cases should really be supported, and the first two shouldn't need the customer to maintain their own VPS to control the storage.

    As things stand, almost everyone wants to sell SAN-based high performance storage that's *expensive* and *fast*, not cheap and slow. Most backup services seem to want you to use their tools or a local appliance to talk to their storage. Half of them act very confused when you mention "Linux" or "UNIX" and ask if that's a new kind of Mac or something. At least in Australia I've found the market miserably unsatisfying so far.

    What I'd really like is for ISPs to begin offering, or partnering with others to offer via peering, bulk near-line storage at moderately affordable rates. That way you can talk to it over your business's main ADSL/SHDSL/fibre/whatever link(s) without dealing with quotas, it's fast, there are multiple routes to it, and it's unlikely to go down if an international link has a hiccup.

    iiNet's cloud offering looked like it might have potential for this, but it turns out to be just another EC2-wannabe crossed with Linode-done-badly-and-expensively. The storage offerings are miserable and they don't even mention whether traffic between iiNet internet services and their cloud is metered

    At the end of the day it comes down to this: who is responsible for keeping your data? With failures in amazon's cloud service, a provider over east in Australia that got hacked and lost all backups, etc - trusting your company's data to someone else is a BIG call to make and understandably, many businesses are wary of the idea.

    At least if the data is stored on premises, and on backup tapes, you have options with regards to data retention/data recovery. Once you upload all your stuff to the cloud, you're at the mercy of your cloud provider. Sure, you may have an SLA, but SLAs mean shit if your company is unable to get access to it's data when required - or would like to prevent third parties from obtaining access to data (such as foreign governments) that the cloud provider may be persuaded or legally required to divulge.

    I signed up for Dropbox and my experience with it is that it's slow as molasses when uploading and I can't just drop a link there and have it point at my server. Nono, I must upload the entire file itself.

    Most people would be better off with Opera Unite. While some here may laugh and point at it because it is not a full-blown server setup, it is probably the easiest ad-hoc file sharing/server program going. Sure, I've personally installed Apache, sftpd and sshd on my home server but just the concepts of these services alone are beyond the grasp of most people. Opera Unite makes this kind of thing drool-proof.

    You declare which directories are shared and that's it. You're done. No uploading to the "cloud" like Dropbox, Skydrive, or Apple's music thingy (and Unite will do media streaming). And you don't get locked in or risk losing control of your data should the cloud service get closed down.
