Congratulations to our friends at Rackspace and NASA Nebula, who launched OpenStack.org today!

Open Stack is an “open source, open standards” stack for Cloud Computing, which includes Compute (like EC2) and Storage (like S3). You can find all the code for Open Stack on Launchpad, as well as the other sub-projects like the iPad and iPhone apps.
This is a huge leap forward, probably the single most important announcement in the industry since EC2.
How does Scalr play into this?
We’re thinking about it. Scalr is currently licensed under the GPL v2, and we’d have to change that to the Apache License which the Open Stack charter requires. The Apache License precludes the dual licensing business model, in which we sell a commercial license to use Scalr for those averse to the GPL.
Open Stack also has a nascent Web UI, with a subset of Scalr’s functionality.
If anyone wants to weigh in here, their thoughts are welcome.
