He's right. OpenStack is far from production, not to speak enterprise. I do not expect it get stable and mature with a year or two. Check out OpenStack mailing lists and bug reports.

I have another name, Stanislaw Lem, with two his novels, Eden and, to a lesser extent, Observation on the Spot"
An extract from Eden:
'An indistinct image emerges of doublers' Orwellian information-controlled civilization that is almost self-regulating, with a special kind of system of government—one that officially does not exist and is thus impossible to destroy. The society is controlled through a fictitious advanced branch of information science Lem dubs procrustics, based on the control and stratification of information flows within the society. It is used for molding groups within a society and ultimately a society as a whole to behave as designed by secret hidden rulers. One example described in the novel is the above mentioned settlement, kind of a "concentration camp" without any guards, designed so that the prisoners stay inside apparently of their own "free" will.'
Please, note this was written in 1959.
