Simple - Relies on a metric e.g. CloudWatch alarm for CPU usage over 80%, must wait for the checks and cooldown to complete before scaling further.

Step - Improves simple, scaling happens in stages. It can continue to scale as it triggers more alarms.

Scheduled - Set times in the day to scale in and out - Predict demand
