As always, it depends ...
First of all you need to write down, what you want to achieve.
Then you have to find the best solution for you. The "best" might be the
most simple, the easiest to maintain, the one with the least effort in
setting up, the one that has least components, the one with the least
complexity or a combination of everything.
What do you want to acchieve? Authentication / Authorization of VPN
client through a central backend database? Do you need accouting?
If your VPN servers do not differ I would set up two RADIUS server (for
redundancy) that use the one database (master / slave setup for redundancy).
If your VPN servers differ and the outcome of your Authorization depends
on the VPN server, I would set up different virtual RADIUS servers.
But everything depends on your setup. Be sure you know what you want.
