I want to re-visit this last comment.

If the group is going to stick with RHEL, and looking forward to
Docker ... is there any reason it hasn't considered a PaaS service,
instead of a full hosting option (that likely runs as a VM)?

OpenShift is Red Hat's existing solution using cgroups, SELinux and
other subsystems, including several of the same used by some Linux
Container (LXC) mechanisms along with some libvirt abstraction, to
contain "gears."  Newer OpenShift developments for even RHEL6, add
full LXC ... which is now, officially, just going the Docker route for
LXC.**

OpenShift Online [1] is provided by Red Hat with up to three (3) small
gears for free.  Custom domains are fine as well in the free account.
The small gears are ideal for PHP, Perl, Python, Ruby, Node.js,
MySQL/MariaDB.  The main advantage of something like a PaaS is that
the sysadmin aspects are handled by the provider, Red Hat in the case
of OpenShift Online.  All you are focused on is the application that
runs on one of those languages and uses one of those DBs.  Probably
the only, big limitation of the free account is the 1GiB maximum
storage.

If anything, even if a PaaS isn't to be considered, it is a pretty
cool solution to "prototype" any new web site that uses one of those
languages and one of those DBs.  The only thing a PaaS won't provide
is a mailing list and archive option, but there are a lot of free
providers that can provide those instead.

Just FYI, for at least prototyping considerations.

**P.S.  In RHEL7, it's the full LXC support, libvirt abstraction,
systemd integration, etc...  Red Hat would likely introduce some
augmentations to OpenShift on-line when those solutions are made
available.
