I'd like to find out if there are plans to enhance ArcSOC Optimizer or whether it's a one-and-done release. I've recently done some work for a client to move a number of their map services over to shared instances. They have concerns that some of their map services that have currently been identified as low use (and subsequently been set to use shared instances) will gain popularity and eventually become mid to high use and no longer appropriate for using shared instances.
Nice post David. Team Esri, I have the same question.
