Scaling Policies in Depth
Target tracking, step, simple, scheduled, and predictive scaling: what each one decides, the cooldown and warmup timers that hold them back, and how AWS resolves several policies pointing at the same group.
Intermediate 28 minutes 5 Learning Objectives
- Select the right scaling policy type for a given demand pattern and constraint
- Explain how a target tracking policy converts a metric into a desired capacity, and which metrics it cannot use
- Build a step scaling policy from step adjustments and predict the resulting capacity changes
- Distinguish a cooldown period from an instance warmup and state which policy types use each
- Describe what predictive scaling forecasts, what it will and will not do, and how it combines with dynamic scaling
