Auto-scaling Efficiency Rate
Definition
Measures effectiveness of an auto-scaling system. The goal of auto-scaling efficiency is to ensure that the right amount of resources are provisioned and de-provisioned in response to changes in demand, in order to achieve a balance between performance, cost, and resource utilization.
Formula, as published
Auto-scaling efficiency rate = Maximum capacity cost of running workload to meet workload demand / Cost of running workload with auto-scaling to meet same workload demand. The higher the efficiency rate the more effective the auto-scaling is. Effective Cost can be used in this formula, or the List Cost metric can be used to eliminate the effect of discounts and focus entirely on the scaling effect.
