Is CentOS Hurting Red Hat? 370

Posted by CmdrTaco
from the can't-imagine-it-would dept.
AlexGr writes "Jeff Gould raises an interesting question in Interop News: Why does Red Hat tolerate CentOS? The Community ENTerprise Operating System is an identical binary clone of Red Hat Enterprise Linux (minus the trademarks), compiled from the source code RPMs that Red Hat conveniently provides on its FTP site. It is also completely free, as in beer. CentOS provides no paid support, but it does track Red Hat updates and patches closely, and usually makes them available within a few hours or at most a few days of the upstream provider, which it refers to for legal reasons as "a prominent North American Enterprise Linux vendor." Free support for CentOS can be found in numerous places around the web, and a few third parties offer modestly priced paid support for those who want it."

    I'm going to have to go with "doesn't hurt Red Hat" on many counts.

    • There's no such thing as bad publicity.
    • CentOS users are likely users who were looking for free anyway so the alternative would have been some other free distro.
    • A natural migration path for free CentOS users would be to require more support and since their universe is Red Hat-centric, the "pay for" version they'd likely choose would be Red Hat.

    I doubt too many sales are lost here.

    And the article's example doesn't really prove the point. So a shop of Red Hat users balked at upgrades and associated fees, and decided to go CentOS because they were a seasoned Linux shop. If it weren't CentOS, it would have been something else. The veteran shops will run Linux for free because they don't need the support, period. And they will find the distro that lets them do that.

    (And I'm not quite sure what the referenced Google graph is supposed to demonstrate. I suspect he's claiming the higher count and increase in hits for CentOS indicates more popularity, and lost revenues for Red Hat, but I see it as those needing to do their own support pretty much start with Google. Red Hat licensees will start with Red Hat support.)

        Well even if we accept that CentOS does hurt RedHat, what can RedHat actually do about it? The GPL stops them from squashing the product (which is exactly the point of the GPL). The GPL provides CentOS with a cast-iron defence from RedHat's legal team. Even if it didn't the reaction of users if RedHat did move against CentOS would be quite something.

        I'm pretty sure RedHat hate CentOS, why all the coy legal mumbo jumbo about who the upstream vendor is otherwise? But actually I see no real downside for RedHat. If you want to "learn" RedHat then CentOS is as good as the real thing (for that) and it really doesn't hurt RedHat to have more people skilled in their product.

        I actually like the CentOS product a great deal - and it fills the void left by RedHat Desktop 9.

          They have to make the source available, but not convenient. Currently they make SRPMs available, which makes the life of Whitebox, CentOS, et al, much simpler. If they really hated such efforts they'd just resort to making only tar balls available. Granted it's a short leap from tar ball to SRPM, but it's a step Red Hat doesn't have to take.

            They need to make SRPMS available to customers. Its trivial for CentOS to be a customer, hence fighting that battle is a losing proposition.

            That said, plenty of evidence exists that Red Hat is OK with CentOS, they are just protecting the Trademarks to avoid losing them.

            The GPL says otherwise: "For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable." It would be a prohibitive amount of work to package up the installation scripts in tarball form (if that is even possible) and then there would be the PR cost of being perceived as a GPL evader.

          RedHat does *not* hate CentOS... the issue has come up on the mailing lists over the years, and some see CentOS as the "gateway drug" that eventually brings more users to RHEL. Others feel that having CentOS around increases the RHEL{,-derived} userbase and therefore indirectly helps increase the quality of RHEL itself.

          In fact, CentOS and Fedora shared a developer booth at FOSDEM this year.

          Linux isn't entirely covered by the GPL; parts of it are BSD, Apache, and other licenses. Furthermore, RedHat could easily use a non-GPL license for some of their contributions.

          CentOS exists because RedHat made the choice to keep things open and available.

          "I'm pretty sure RedHat hate CentOS."

          1. No, we don't. At least, not most of us -- because most of us actually *understand* the business we're in. That's why we're making all this nice money. If we did hate CentOS, we could make it awfully difficult for them in any number of ways -- delaying updates, hiding marks and making them play "where's Waldo" every release, that sort of thing.

          2. The "coy mumbo jumbo" about the upstream vendor has to do with trademark protection, not hate. We don't want "Red Hat" to turn into "Kleenex".

          3. Here's a question: why is there no CentOS equivalent based on SuSE products? Think about it.

          4. A lot of the significant people in the CentOS community are actually important and respected members of the Fedora community as well. That way, Red Hat benefits from the work of the more savvy CentOS users. That's how open source works, you see.

          5. It's Red Hat, with a space. Not RedHat. Get it right, or we'll send you a cease-and-desist letter. (I'm kidding. Probably.)

            I'm glad Red Hat's folks "get it". Personally, I have no need for a multi-gazillion dollar support contract for my home webserver. But it's sure nice to have one that has the same sort of product support lifecycle as RHEL, and is set up exactly the same. In return, you know what gets specified as the OS of choice on all of my mission-critical boxes at work? You got it - RHEL, with support contracts. Because at work, my boss feels I have more important things to do than compatibility testing and chase around weird OS bugs, and we've been pretty happy with RH so far.

            A big thanks to RH for continuing to support the community by not throwing a wrench into projects like CentOS, Whitebox, etc...

        Indeed! My company will (for the foreseeable future) need some RHEL licenses for the applications which the vendor only supports on RHEL, like SAP. We may run other things on CentOS, but if we didn't run them on CentOS, we'd probably run them on Debian; it's all either common free software or software we wrote ourselves and we don't feel like paying Red Hat for their product. SInce we can, effectively, run one quite similar OS all over without having to pay Red Hat for all of it, we do, and that's why we're not entirely leaving Red Hat. I can't believe we're the only company doing this. If Red Hat demanded that anything we ran that looked even vaguely like their OS had to be paid for, we would run entirely Debian/Ubuntu and start pressing application vendors to support Debian/Ubuntu and we would not be alone, and application vendors would give in, and then Red Hat's market would entirely evaporate.
        (Red Hat are not endearing themselves to us any by being further behind the feature curve than we would like, and by generally having quite unhelpful support if we have a problem - we perceive their added value to be small)

      Not only that, but it's entirely possible that people who have Red Hat systems (and Red Hat support) but are looking for a quick answer might do searches on CentOS sites. Similarly if you have an Ubuntu system you may very well do searches on Debian support (or vice versa) since the answers are usually interchangeable.

      As you said, if you have a supported Red Hat install, you're not very likely to be doing as many random Google searches in the first place. The rise in CentOS searches since its inception points to more interest in that distro, yes, but that by association also means more interest in Red Hat systems.

      I should also note that when I played around with Fedora, I found it somewhat unstable (not trying to start a flamewar here!)... which in a sense made me wonder about Red Hat as a distro. But then my experiences with CentOS showed me how stable and well put-together it actually is, which increased my opinion of RHEL.

      What I'm trying to say is, the fact that CentOS is such a solid distro is good publicity for Red Hat, because people get to sample the enterprise-quality polish and updating before they commit to support contracts. Red Hat's secret sauce has never been the binaries; it's always been the reputation for good support. And CentOS adds to this perception of a quality product; a net gain for Red Hat.

    CentOS essentially acts as advertising for the Enterprise RedHat editions. It allows sysadmins to stick with the same familiar set of tools on both systems where it is considered desirable to have a support contract and systems where this is less of an issue.

    RedHat can't do much to curb this anyway - most of what they produce is standing on the shoulders of other GPL software - but if they did, I'd imagine we'd see a commensurate rise in the use of Debian, Ubuntu and (gasp!) SuSE/OpenSuSE.

          Not entirely correct. Installation scripts and interfaces definition files must be included. Access to CVS/CVN of the code without these would not satisfy the GPL (v2).

          Wasn't aware of that, but you still need the configuration files. E.g. sendmail.cf, httpd.conf, etc. for the various configurations. A lot of these are readily available but things like Selinux policy files, pam configurations, etc. are redhat specific and wouldn't need to be distributed or may be distributed using a restrictive license.

      Red Hat is also a creator of a significant body of GPL code

      And in that area, they do have a choice. For all those GPL components where Red Hat owns the copyright, they could decide to change future versions to a different license. So far they haven't done this, and I don't think they are going to. I can think of a few reasons why Red Hat would not close those components:

      • There might be small parts of the code which is not owned by Red Hat.
      • They might think the improvements that other parties can make to th
  • I looked into RHEL when they dropped support for RH 8/9, and they wanted far more money than I was willing to pay to kick around the tires at home or on my development box. When time came to look at 'enterprise' grade distributions, SuSE made it much easier on the developers. Fast forward and I found that I never bothered to even try RHEL 3, 4, and 5. Same went for Oracle's branded version. With no easy way to patch and having to deal with accounting to get a license, meh.

    What changed it for me was Centos. I found that I could use the free as in beer versions for all my personal/internal needs, and it was so dang close to OEL and RHEL it became a no-brainer for testing and some dev work. With the internal blessings from our side that our code would work, QA did the formal testing on the branded versions of Linux. Folks running our product, of course, would want OS support - so they purchased the formal 'supported' OS from the commercial vendors. I suspect Centos is saving RHEL/OEL sales that might have gone to Ubuntu or other variants.
  • Red Hat makes money selling services to big companies who can't afford to be wrong. They sell CYA insurance to suits. CentOS is probably a plus, as it lets people test drive the real thing for free. When you have to put your career on the line in a large company, you pay Red Hat to Cover Your Ass. They are good at it, and the rate of pay reflects it.

      Yeah when I was doing a Computer related degree in College they used CentOS because of that fact. The thing is you're more likely to encounter RHEL than Debian, Ubuntu and such for server work. They exploited the fact that CentOS was a free version of RHEL and now RHEL has about 20-30 more people with college degrees that have been introduced to their work.

      Myself I've used Ubuntu series of Linux on my home machine because its better for desktops but if I were to run a server I'd probably choose CentOS for myself (or a small business), RHEL if I had a big budget in a major company.

    Did we miss the point of the GPL? The instance of the software is owned by the user. They can do what they want with it. If they feel like doing everything on their own, they can do so (CentOS). If they want to pay someone else to make their life easier, they can do so (RedHat). RedHat knows this. "Choosing" to tolerate is the one choice RedHat doesn't have: If RedHat wants to use GPL'd software, they have to let other people play by the same rules they do. CentOS isn't going to hurt RedHat any more than Debian does.
  • I don't think Red Hat is tolerating it. They simply have no choice. The OS and most of the components installed with it are licensed under the GPL, which states that exactly this sort of thing can happen.
  • It's all (I believe) GPL, so they HAVE to provide the source, and there's nothing to prevent someone else compiling and releasing it as CentOS does. They'll just have to deal with it.

    One of the things that makes CentOS a clear winner is that because it is a completely compatible recompilation of RH, going from a test CentOS install to a fully supported RH entitlement is very easy. Thus I install CentOS initially on all my servers initially and then when I put them into production, I convert them to RHEL and buy an entitlement for them. Some of my less important servers remain CentOS. One of the main reasons for converting my servers to RHEL is that I can watch over them all, in terms of patches and security eratta, from the RHN.

    In other cases, I can convert a RHEL box to CentOS, then build the replacement server with its entitlement, allowing me to keep the original server in production for a few weeks or months while the new server is ramped up.

    So if anything CentOS actually increases RH usage because it is so easy to, at any time, buy entitlements from RH, convert the CentOS machines, and get whatever level of support you deem necessary at the time.

      CentOS also has a much larger set of available binary software packages than redhat.

      Of course, you can use those packages with either redhat or CentOS. So while CentOS benefits from all of redhat's core OS work, Redhat benefits from all of CentOS's package maintenance work.

      Without a doubt, each project benefits the other directly.

    I work from a company that runs most of its products on top of Redhat EL3 and EL4. While there is something to be said about Redhat's quality of support- for inhouse development wortk it isn't so important. Its value comes form supporting our customers at an OS level alleviating us from supporting the OS. (We require our customers to purchase Redhat support contracts). What I believe _is_ hurting redhat is how their sales department insists that making copies of Redhat is illegal. We have been told time and time again that it is illegal for us to run copies of Redhat that are not paid for within our support contract. The truth is- as long as you aren't expecting support for the unpaid for copies and you are not selling them to other companies (alone or as part of your product, because of redhat trademarks) it is fine to use as many inhouse copies as you want. It took me monthes to convince management at our company that Redhat Licensing is completely different beast than, say, Windows Server licensing while at the same time fighting a battle with the software programmers trying to convince them that Linux is _not_ freeware. The concept of GPL'd software seems to be lost on members of the IT management sector. CentOS has become a good inhouse alternative to redhat since it is binary compatible, but it does not displace any copies of Redhat sold with our product. So, while Redhat may be losing some marketshare for inhouse deployments, they are only losing cusotomers that didn't want the support or that they were essentially *lying* to by requiring them to purchase licenses they were not obligated to purchase.

    RHEL, CentOS, and Fedora are all competing brands under the same umbrella. Fedora is great for cutting edge developers and home users. CentOS is good for people who desire the better tested software. RHEL is targeted at enterprises (hence the 'E' in the acronym) who need things working all the time (99.9999%). The three different markets are comparable to the different brands offered by Microsoft (Server, Workstation, Home). The only difference is that Red Hat doesn't make any money from CentOS or Fedora.

    But take a step back and think about Microsoft a bit more. Imagine you have a business laptop which was provided to you by your company. It runs 2000 or XP or (god forbid) Vista and the company has a site license for you to run that software. Microsoft is happy to slash margins for the individual site license which you have as long as they can continue to service the servers and infrastructure which run the business critical systems of your company. Similarly, if you are a developer or home user... your copy of Windows came from an OEM or you pirated it. Sure, Microsoft gets money from Dell and the other OEMs... but (I imagine) so do the Linux companies who have been able to get involved in that method of distribution.

    In the end, you help Red Hat by using CentOS or Fedora just like you help Microsoft by using pirated Windows. Simple enough?

    Not only does Redhat 'tolerate' CentOS (see above), it also puts money into encouraging people to use Fedora, which is not only free but generally significantly more advanced than RHEL. For people who want free software and enjoy recompiling their kernel, Fedora is a much more obvious choice than a clone of CentOS.

    There was never any money in selling distros to dorm-room techies, and RHEL was never a good distribution for that market, because it's so conservative. I run Ubuntu on my desktop machines, because it's free, and it works, and it has all the multimedia stuff that RedHat don't ship as standard. On my company's production servers it's RHEL every time, because it's stable, because it will still be supported in 5 years' time if necessary, and because RHEL is a de facto standard in hosting terms. If a client's code doesn't work with RHEL, we can tell them to fix their code. If we were running some wacky, customised version of Gentoo they'd tell us to fix our server (whether or not anything was broken).

    Running CentOS would give us the conservatism of RHEL without any of the respectability. I can't see how that would be useful to us.

    1) Its open source, its not a question of tolerating Centos, its the way open source works.

    2) The anecdotal evidence is seriously flawed. His buddy was running an old and unsupported version of Red Hat Linux (7.3), and they were not paying for a service subscription, and they decided to go with Centos and continue to not pay for a support subscription. Uhh, clue here, this did not effect Red Hat in any way, they are not Red Hat's target market, if it wasn't Centos it would have been some other distro.

    3) And again, the conclusion is completely clueless. Red Hat does not change the way they do business becuase their business is based on open source. If Red Hat decided to develop their own closed source proprietary operating system they would lose the support and synergy of the massive open source community and their business would flop.

    These articles are tiresome and poorly researched. Why is it that everyone believes the only way to have a viable business today is to create a monopoly and change the way you do business to ensure there is no competition that can "sting" you. Red Hat is doing an outstanding job of monetizing a viable market, linux service, support, and training. If Jeff wants to understand why Red Hat does not change their business model all he has to do is read up on the history of Caldera/The SCO Group to see what happens when a linux distributor changes their business model and tries to monetize off the "IP" instead of the service and support they were originally established to provide as a business model.

    The CentOS userbase is an incentive to make your software Redhat-compatible. If there were not a free and painless option that is compatible with RH, many more people would have switched to SuSE, Ubuntu, etc.

    CentOS is actually significantly better than RHEL in one respect, though. The package management system, yum, has always been more reliable for me than RHEL's up2date. Even now that RH uses yum, their reposistories seem to be down or slow fairly often. And I can't stand using RHEL's web site. It's much faster to deploy a CentOS server than a Red Hat one, enough so that the price difference seems almost secondary. On the other hand, if you install a lot of machines, you shouldn't be doing it from scratch.

    Eh, but Red Hat's done far more good things than bad things. I think CentOS (and to a lesser extent, White Box and others) have a nice symbiotic relationship with them. Some users will prefer or need officially supported software, and that's why they're still turning nice, but not monopolistic insane profits. It would be a mistake to think that they'd get many of the CentOS users if they could only work around that pesky GPL and force them to buy from Redhat. Quite the opposite; they'd ruin themselves.

    It's very simple. Red Hat Enterprise Linux is for the Enterprise, that's what they sell. Same thing for SuSe(though with some extensions). They sell rather expensive support contracts to organizations large enough to require them, folks don't pay that kind of money because they can't get the product some other way, they pay it to not have to have linux developers on staff, and to have support and limited culpability from a third party. Red Hat might lose a few boundary cases(people who want an enterprise style system but don't want support), but it's not going to be a major drama for them.

    My servers run Debian GNU/Linux 4.0 etch amd64. If for any reason I couldn't get Debian and I wanted a RedHat-like distro, then I would examine CentOS. If it suited me, then I would examine the pure RedHat. But if I couldn't get CentOS, then there would be absolutely no chance of even thinking about RedHat.

    To summarise... If I were a CentOS user I would be willing to consider RHEL, but if there were no CentOS I would *never* buy RHEL. I wouldn't get RHEL even if it, its updates, and its support were offered for free.

    Let me explain my reasoning as a user: RHEL is supported by a company. CentOS is supported by a community. Companies may die or bought by a bigger company and leave their users unsupported. Communities, while having no obligation to support the users, tend to live on and almost never die. "Dead" communities are usually just replaced by a new more vibrant one. The reason is that communities are formed because of the needs of developers and users, so for as long as users have the same needs there will always be communities covering these needs. Companies, however, are usually formed for profit, so if you have obscure needs that cannot bring profits to an enterprise then you may be unable to buy a commercial solution to your needs. A company can cease its operations for various reasons. This can't happen with a community. With an active CentOS community around, this means that upgrading to the enterprise support offered by RedHat is safe: Even if RedHat can't support me, I can always just revert back to CentOS and carry on my business as before with no changes. But if CentOS didn't exist, then getting RedHat would mean that you would assume the risk of having business continuity problems if your support provider went out of business etc. With CentOS around acting as a backup, RedHat is a much more safer choice.

    Let's use an actual example: I still have a Commodore 64 home micro from the 1980s with its sexy tape drive, but Commodore is no more and doesn't support this old model anymore. I have to rely to an informal community to get spare parts from auctions, classified ads, etc. The company has stopped supported the C64 users, but the C64 community is still alive and supports its members very well.

    Really, the knowledge that CentOS has good compatibility with RHEL and that I will *never* face the same situation as my did with my C64 makes me a thousand times more willing to buy RHEL if I ever need their enterprise support. Buying RedHat means that if I can't continue running it then I can just revert back to CentOS with little effort.

    In this sense, every commercial distributors should seek to support a compatible community-led parallel distro alongside their commercial offering. Community distros that are compatible with commercial versions achieve synergy benefits for both the community and the commercial vendor. Furthermore, companies should not be afraid of losing customers from the community version, as commercial and community distros are meant for very different kinds of users. In the CentOS/RHEL example, the difference between CentOS and RHEL is that with CentOS you are responsible for keeping your machines operational, while with RHEL you can sign a contract and give portions of your responsibility to RedHat. This usually appeals to middle level managers who get to make a choice between distros and have a higher boss to report to in case somethings gets broken. But CentOS, just like Debian, will appeal to techies and entrepreneurs who either know what they are doing or have no one above them to fear getting fired. So, really, these distros target very different markets and very different psychologies of customers.
