Amazon EC2 Auto Scaling

Amazon EC2 Auto Scaling is the AWS service that maintains and adjusts the number of Amazon EC2 instances in customer-defined Auto Scaling groups using manual, scheduled, dynamic and predictive scaling. Native predictive scaling succeeded the prediction approach previously offered through AWS Auto Scaling scaling plans.

• Predictive scaling — ML forecast-directed capacity scale-out

  Active · verified 2026-10-02

  Amazon EC2 Auto Scaling predictive scaling uses machine-learning-based forecasting of historical workload patterns to predict future demand and derive hourly capacity requirements. In ForecastAndScale mode, Amazon EC2 Auto Scaling can automatically scale out an Auto Scaling group when forecast capacity exceeds current capacity, causing EC2 instances to be launched ahead of predicted demand. Predictive scaling itself does not perform forecast-driven scale-in when predicted demand falls; AWS documents dynamic scaling as the mechanism for removing excess capacity.
