Capture existing user input and replay captured user load until autoscale is triggered on all layers. Simultaneously, terminate all resources in one of the zones.

Create synthetic random user input, replay synthetic load until autoscale logic is triggered on at least one layer, and introduce chaos to the system by terminating random resources in both zones.

Expose the new system to a larger group of users, and increase group size each day until autoscale logic is triggered on all layers. Simultaneously, terminate random resources in both zones.

Capture existing user input and replay captured user load until resource utilization exceeds 80%. Also, estimate the number of users based on existing users' usage of the app, and deploy enough resources to handle 200% of the expected load.
