There's nothing magic about it, really. You need to decide what you want first.

For example, on out setup. the NAS (i.e. BRAS) and other internal
systems (including radius and billing) are connected using internal
private network. We put radius servers on multiple locations,
connected to that internal network. That way, if one radius location
goes down, or even if the whole internet goes down, users will still
be able to authenticate.

Now when you say "radius in the cloud", it can either mean:
- you have and manage radius servers in multiple locations accessible
from internet. Again, nothing magic about this. It should just work
provided you have ways to synchronize data between radius servers
(e.g. using db replication or whatever). OR
- someone else will manage radius service for you. There are companies
that provide that, and it should work, though personally I haven't
tried any of them.

Either one should work, assuming you already know what you want and
create a suitable design for it.
