A cluster is very reliable as nodes (slaves) can be added and removed
for individual admin needs, keeping 'the beast' HA. You can even put
part of your cluster (for redundancy and peak loading) partially on a remote
DatatCenter like 'rackspace'; should the HA requirements be such to justify
the extra expense. Or a smaller vendor on another network; reciprocity style.

I hope to have mine up by Christmas.

Here is something that many are playing with::
https://github.com/mesosphere/mesos-dns/blob/master/README.md

Many are posting about the wonderfulness and stability of web services
even on a smaller cluster.
ymmv.
