Just saw Rackspace just announced OpenStack, the open source software that powers its cloud computing platform. Currently licensed under Apache 2 license. There is a big list of big names showing interest in this project, which basically allows companies to run its own cloud platform — useful in the situation where “data stored on 3rd party computers” are taboo words (i.e. finance sector where I am currently working at).
You can get the documentation for both storage (Swift) and computing Nova). Very Pythonic. According to Hacker News, Swift is pretty much production ready as it’s the code behind Rackspace CloudFiles. I wonder whether Nova actually resembles CloudServer code, which would be related to SliceHost’s manager/console?
