The summary does not tell me what this thing, apparently popular in Beijing, actually is! You could at least link their website.
Anyway, looking at their website, it looks like it's a "cloud operating system", i.e. infrastructure for managing a cluster in a virtualized, "cloud-like" way. Does anyone know how it compares to other such platforms, like Eucalyptus and the confusingly-similar-in-name CloudStack?
