They rebranded Tutum which they just bought Docker Cloud, or am I missing something? Are they going to do the hosting part too now?

No, that's exactly it. The container images still reference "tutum". They're not doing hosting, but "bring your own node" works. Kinda.

Where's the video? I kind of expect an announcement like this to come with a video demo that is impressive or else why bother?

Heh, from dotCloud to Docker and back again. I wonder how the investors in the insolved dotCloud feel about this.

dotCloud provided infrastructure (compute nodes with memory/cpu limits), which they wanted to quickly distance from. Docker Cloud is BYOI (bring your own infrastructure) such as Digital Ocean, AWS, Azure, Softlayer. It's basically Tutum out of beta, similar to CoreOS tectonic but less enterprise targetted (pricing upfront, freemium, can use $5/mo DO droplets). It's a managed control panel essentially. CPAS - Control panel as a service?

I liked Tutum (and thus Docker Cloud) as a rapid path to get up and running, but the higher level concepts of Kubernetes appeal more to me for real worl projects.. (note: Kubernetes uses docker and docker images)

So does anyone actually intend to use this?

I spent today using it. I don't intend to do it again.

Sounds about like my experience using Docker Hub. I'll be back in a few years.
