I work for large ISP we generally put DC, which has many definitions but in
many cases it is a location with a few connections but total resilience
within those connections, we would normally connect these a nssa ( nssa just
in case we need to redist something in the future). The DC routers just want
to send data out, quickly so a small routing table is a good idea so I would
have thought even a nice tidy area 0 would have a bit more information that
is really needed. But as DC can mean many thing to different people this
might not be ok for your requirement.

Thanks guys.
So if you had two data centers, would you put both data centers in area 0 or
would you use a different area number for each data center?
