AWS Auto Scaling

AWS Auto Scaling adjusts compute resources to handle fluctuating demand. It manages scaling policies across multiple services, ensuring your infrastructure adapts automatically to traffic spikes or lulls without manual intervention.

This fits teams needing dynamic capacity management. However, there is no free tier, so you pay for every scaled instance. The pay-as-you-go model means costs rise directly with usage, requiring careful monitoring to avoid unexpected bills during heavy scaling events.
