Only OpenStack is fully open source and fairly feature complete, with a few dozen providers using the OpenStack platform.
OVH, who owns the largest datacenter in North America uses OpenStack, they're actually one of the largest contributors. Red Hat & IBM both seem to be really pushing private deployments as of late for their larger clients that already own large DCs.
You missed Red Hat, who seem to be the only company having major success with OpenStack [1]
Most of IBM, Intel, HPE etc have thrown in the towel and now offer their own services on top of Red Hat OpenStack.
OpenStack has now found itself beyond enterprise, and now being the de-facto platform for NFV running mobile networks, and I guess Red Hat are becoming the winner here as they are so used to supporting an OpenStack 'type of' infrastructure for large bodies such as banking, telco, health etc. When you consider Red Hat are already large well established contributors to all of the layers of the OpenStack 'stack' such as KVM/QEMU , libvirt, the kernel itself, + overlay networking tech such as OVS, and now DPDK, you can see why they are well positioned to support and run OpenStack clouds.
Many of these are older than OpenStack by a wide margin. OVH in particular is huge, they own many data centers, thousands of employees...you just don't make that sort of switch overnight. The cost and risk might not be justifiable.

I'm a big fan of [OpenStack](https://www.openstack.org/) as it is open source and definitely enterprise-grade.
OpenStack is open source. It can be forked, modified, whatever. Let me know when you manage to build your own AWS cloud with Amazon's software and then I'll entertain the thought that they are comparable.
Redhat, IBM, Rackspace, HP are pretty major players (and there are users like HP, Bloomberg & IBM research). You can find them https://www.openstack.org/foundation/.
While I don't have any first hand experience contributing to OpenStack (but complained quite a lot back in the old days as user), most of the developers are paid. Obviously OpenStack started out with NASA and (then) Rackspace, so it totally makes sense folks there held the manager/committer/BDFL titles and drove the decisions.
I do agree many of the APIs are awkaward and the Python code is not very Pythonic (classic example: why are attributes with "-" exist?? as user I have to use getattr(object, "OS-XXXX") to retrieve the value). Oh my god.
Sure, but Openstack-based public clouds are in short supply (unfortunately? fortunately?). I think the short explanation is that pure OSS stacks limit providers ability to move fast and differentiate. So it’s a race the bottom for Openstack-based providers. (Rackspace’s gambit was quite different, as they were arguably trying to do exactly that.. comoditize cloud services.)
As someone who works for a non-major datacenter. We use VMware and have evaluated OpenStack. Lots of moving parts for OpenStack, administrative burden. So we don’t use OpenStack.
I'm surprised no one mentioned openstack. I never deployed it, but by mere reading its deployment docs, its going to be a mess in production and its not doable by a solo dev. Anybody care to correct me?
OpenStack is designed to be a collection of projects that together can be used as the basis of a scalable cloud deployment (public or private). Currently, there are two big projects in OpenStack: nova and swift.
Nova can be compared to EC2. It is designed to provision compute instances, and it's goals are to support a million physical hosts with many times that for VMs running on the hosts. It is currently under active development and used in production at NASA.
Swift is a scalable object storage system similar to S3. It's designed to support 100+ petabyte clusters each with 100000 requests per second, tens of thousands of hard drives on thousands of storage nodes. It is currently running in production at Rackspace as Cloud Files.
Unlike AWS or Eucalyptus, OpenStack is 100% open--both source and development.
The claim of "the new Linux" comes from the thought that Linux was an open OS that changed the way servers ran. OpenStack's goal is to be the OS for the data center. It's a layer above the individual machines and ties together the IaaS pieces needed for a DC.
Disclosure: I work for Rackspace and am a developer for swift.
