I'm running a legal SQL Standard server with 1 instance for our SolareWinds database (awesome product). Howerver, I have been tasked to move our WSUS and Mcafee AV databases over too the same server. The server can handle the workload, that's not an issue, my question is should I create a seperate Instance for each applicaiton? Or should I just add them too the same instance. The reason I ask is because I know I can control the memory allocation at the instance level, not at the DB. So what is the best practice for this?
