OpenStack is not in competition with VMware. OPenStack != VMware. They
do share some common ground, overlap if you will, but don't share the
same space in it's entirety. That misconception causes me no shortage
of pain at my job.
Ovirt/RHEV = VMware
and I do run RHEV at work. It is quite nice and feature-full, though it
is not enterprise ready. What that means is, it does not cost enough to
be worthy of using in the enterprise. We will not even bring up the
cost of Ovirt, which is $0 per server, because, as we all know, there is
no such thing as software that costs $0, is there? And everytime I
bring it up, I lose credibility, seriously.
Jim what do you mean "PluscI can lock down user access with FreeIPA
:-)" ? What is this Pluscl?
