Active Administrator

New Installation of AA 8.2

Hello,

I am building out a new installation of Active Administrator 82 and I am looking for best practice recommendations on server and DB requirements.  I plan on installing AA on its own dedicated 2012R2 server however I am not certain if I should spin up a separate SQL DB server or not for best performance, logging, etc.  Environment is roughly 600 active users and servers are virtual. 

Just want to build it right... once.  Any suggestions are appreciated.
