Why each option
To meet the requirements of 4 customers each needing a separate application instance, auto-scaling, deployment slots, and isolated networking with minimized costs, the most efficient approach is to deploy each customer's application to a separate App Service Plan within an App Service Environment (ASE) v3, with each plan running at its minimum of one instance.
Running 16 instances (4 instances per customer) would significantly increase costs without a clear justification from the "minimized costs" requirement and the "separate individual instance" phrasing.
Running 8 instances (2 instances per customer) would increase costs unnecessarily if 1 instance per customer is sufficient to meet "separate individual instance" and "minimized costs."
Running 12 instances (3 instances per customer) would similarly increase costs beyond the "minimized costs" requirement when a single instance per customer's dedicated plan is sufficient as a starting point.
To satisfy the requirements for 4 customers needing separate application instances, auto-scaling, deployment slots, and an isolated network (implying an App Service Environment), while minimizing costs, each customer should have their own App Service Plan configured within the ASE. Since an App Service Plan can be scaled down to a minimum of one instance to host an application, a total of 4 instances (one per customer's App Service Plan) would be running.
