OpenStack, community, and commercialization

I wrote, the other day, about Citrix buying Cloud.com, and I realized I forgot to make an important point about OpenStack versus the various commercial vendors vying for the cloud-building market; it’s worthy of a post on its own.

OpenStack is designed by the community, which is to say that it’s largely designed by committee, with some leadership that represents, at least in theory, the interests of the community and has some kind of coherent plan in mind. It is implemented by the community, which means that people who want to contribute simply do so. If you want something in OpenStack, you can write it and hope that your patches are included, but there’s no guarantee. If the community decides something should be included in OpenStack, they need some committers to agree to actually write it, and hope that they implement it well and do it in some kind of reasonable timeframe.

This is not the way that one normally deals with software vendors, of course. If you’re a potentially large customer and you’d like to use Product X but it doesn’t contain Feature Y that’s really important to you, you can normally say to the vendor, “I will buy X if you had Y within Z timeframe,” and you can even write that into your contract (usually witholding payment and/or preventing the vendor from recognizing the revenue until they do it).

But if you’re a potentially large customer that would happily adopt OpenStack if it just had Feature Y, you have miminal recourse. You probably don’t actually want to write Feature Y yourself, and even if you did, you would have no guarantee that you wouldn’t be maintaining a fork of the code; ditto if you paid some commercial entity (like one of the various ventures that do OpenStack consulting). You could try getting Feature Y through the community process, but that doesn’t really operate on the timeframe of business, nor have any guarantees that it’ll be successful, and also requires you to engage with the community in a way that you may have no interest in doing. And even if you do get it into the general design, you have no control over implementation timeframe. So that’s not really doable for a business that would like to work with a schedule.

There are a growing number of OpenStack startups that aim to offer commercial distributions with proprietary features on top of the community OpenStack core, including Nebula and Piston (by Chris Kemp and Joshua McKenty, respectively, and funded by Kleiner Perkins and Hummer Winblad, respectively, two VCs who usually don’t make dumb bets). Commercial entities, of course, can deal with this “I need to respond to customer needs more promptly than the open source community can manage” requirement.

There are many, many entitities, globally, telling us that they want to offer a commercial OpenStack distribution. Most of these are not significant forks per se (although some plan to fork entirely), but rather plans to pick a particular version of the open source codebase and work from there, in order to try to achieve code stability as well as add whatever proprietary features are their secret source. Over time, that can easily accrete into a fork, especially because the proprietary stuff can very easily clash with whatever becomes part of OpenStack’s own core, given how early OpenStack is in its evolution.

Importantly, OpenStack flavors are probably not going to be like Linux distributions. Linux distributions differ mostly in which package manager they use, what packages are installed by default, and the desktop environment config out of the box — almost cosmetic differences, although there can be non-cosmetic ones (such as when things like virtualization technologies were supported). Successful OpenStack commercial ventures need to provide significant value-add and complete solutions, which, especially in the near term when OpenStack is still a fledgling immature project, will result in a fragmentation of what features can be expected out of a cloud running OpenStack, and possibly significant differences in the implementation of critical underlying functionality.

I predict most service providers will pick commercial software, whether in the form of VMware, Cloud.com, or some commercial distribution of OpenStack. Ditto most businesses making use of cloud stack software to do something significant. But the commercial landscape of OpenStack may turn out to be confusing and crowded.

Citrix buys Cloud.com

(This is part of a series of “catch-up” posts of announcements that I’ve wanted to comment on but didn’t previously find time to blog about.)

Recently, Citrix acquired Cloud.com. The purchase price was reported to be in the $200m+ vicinity — around 100x revenues. (Even in this current run of outsized valuations, that’s a rather impressive payday for an infrastructure software start-up. I heard that VMware’s Paul Maritz was talking about how these guys were shopping themselves around, into which some people have read that they ‘had’ to sell, but companies that sell themselves for 100x trailing revenues don’t ‘have’ to be doing anything, other than sniffing around to see if anyone is willing to give them even more money.)

Cloud.com (formerly known as VMOps) is one of a great many “cloud operating system” companies — it competes with Abiquo, OpenStack, Eucalyptus, Nimbula, VMware (in the form of vCloud Director), and so on. By that, I mean that you can take Cloud.com and use it to build cloud IaaS of your very own. While you can use Cloud.com to build a private cloud, the reason that Cloud.com commanded such a high valuation is that it’s currently the primary alternative to VMware for service providers who want to build public cloud IaaS.

Cloud.com is a commercial open-source vendor, but realistically, it’s heavily on the commercial side, not the open-source side; people running Cloud.com in production are generally using the licensed, much more featureful, version. Large service providers who want to build commodity clouds, particularly on the Xen hypervisor (especially Citrix Xen, rather than open-source Xen), are highly likely to choose Cloud.com’s CloudStack product as the underlying “cloud OS”. We’re also increasingly hearing from service providers who intend to use Cloud.com to manage VMware-based environments (using the VMware stack minus vCloud Director), as part of a hypervisor-neutral strategy.

Key service provider customers include GoDaddy and Tata Communications. A particular private cloud customer of note is Zynga, which uses Cloud.com to provide Amazon-compatible (and thus Rightscale-compatible) infrastructure internally, letting it easily move workloads across their own infrastructure and Amazon’s.

Citrix, of course, now has a significant commitment to OpenStack, in the form of Project Olympus, their planned commercial distribution. The Cloud.com acquisition is nevertheless complementary, though, not competitive to the OpenStack commitment.

Cloud.com provides a much more complete set of features than OpenStack — it’s got much of what you need to have a turnkey cloud. Over time, as OpenStack matures, Cloud.com will be able to replace the lower levels of its software stack with OpenStack components instead. For Citrix, though (and broadly, service providers interested in VMware alternatives), this is a time-to-market issue as well as a solution-completeness issue.

In my conversations with a variety of organizations that are deeply strategically involved with OpenStack and working in-depth on the codebase, consensus seems to have developed that OpenStack is about 18 months from maturity (in the sense that it will be stable enough for a service provider who needs to depend on it to run their business to be able to reasonably do so). That’s forever in this fast-moving market. While Swift (the storage piece) is currently reliable and in production use at a variety of service providers, Nova (the compute piece) is not — there are no major service providers running Nova, and it’s acknowledged to not be service-provider-ready. (Rackspace is running the code it got via the acquisition of Slicehost, not the Nova project.) Service providers want to work with proven, stable code, and that’s not Nova right now — that’s Cloud.com. (Or VMware, and even there, people have been touchy about vCloud Director.)

It’s not that the service providers have a deep interest in running an open-source codebase; rather, they are looking for an alternative to VMware that is less expensive. Cloud.com currently fills that need reasonably well.

Similarly, it’s not that most of the members of the OpenStack coalition are vastly interested in an open-source cloud world, but rather, that they realize that there needs to be an alternative to VMware’s ecosystem, and it is in the best interests of VMware’s various competitors to pool their efforts (and for vendors in more of an “arms merchant” role, to ensure that their stuff works with every ecosystem out there). Open source is a means to an end there. Cloud.com’s stack, whether commercial or open source, is only a benefit to the OpenStack project, in the long term.

This acquisition means something pretty straightforward: Citrix is ensuring that it can deliver a full service provider stack of software that will enable providers to successfully compete against vCloud — or to have hypervisor-neutral solutions peacefully coexist, in a way that can be easily blended to meet business needs for a broad range of IaaS solutions. While Citrix would undoubtedly love to sell more XenServer licenses, ultimately the real money is in selling the rest of its portfolio to service providers — like NetScaler ADCs. Having a hypervisor-neutral cloud stack benefits Citrix’s overall position, even if some Cloud.com customers will choose to go VMware or KVM or open-source Xen rather than Citrix Xen for the hypervisor.

It certainly doesn’t hurt that Cloud.com’s Amazon-compatible APIs (and thus support of RightScale’s functionality) is also tremendously useful for organizations seeking to build Amazon-compatible private clouds at scale. No one else has really addressed this need, and VMware (in an infrastructure context) has largely targeted the market for “dependable”, classically enterprise-like infrastructure, rather than explored the opportunities in the emerging demand for commodity cloud.

In short, I think Cloud.com is a great buy for Citrix, and VMware-watchers interested in whether or not their vCloud service provider initiative is working well should certainly track Cloud.com wins vs. vCloud wins in the service provider space.
