What is AWS Auto Scaling?
AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. The service provides a unified scaling interface for multiple AWS resources simultaneously.
Instead of configuring scaling policies for each service separately, AWS Auto Scaling creates scaling plans that manage resources for EC2 Auto Scaling Groups, ECS services, DynamoDB tables, and Aurora replicas in a single view. The service uses predictive scaling based on machine learning to forecast traffic spikes and proactively provision capacity.
Core Features
- Scaling Plans: Unified scaling policies across multiple AWS services
- Predictive Scaling: ML-based prediction of load patterns for proactive capacity adjustment
- Target-Based Scaling: Automatic resource adjustment to defined target values (e.g., CPU utilization)
- Cost Optimization: Balance between performance and cost through intelligent scaling strategies
- Multi-Service Support: EC2, ECS, DynamoDB, Aurora, Spot Fleets in one interface
Typical Use Cases
Web Applications with Variable Traffic: Scale EC2 instances and DynamoDB capacity simultaneously when traffic increases. AWS Auto Scaling adjusts all resources in coordination without configuring each service individually.
Cost Optimization: Define scaling policies that automatically reduce unused resources during off-peak hours. Predictive scaling recognizes recurring patterns and provisions capacity exactly when needed.
Microservice Architectures: Manage the scaling of ECS services and their database backends centrally. AWS Auto Scaling ensures all components scale proportionally.
Benefits
- No additional cost for the scaling service itself
- Unified configuration across multiple AWS services
- Predictive scaling prevents performance drops during traffic spikes
- Automatic cost reduction during off-peak hours

Frequently Asked Questions
What is AWS Auto Scaling?
AWS Auto Scaling is a service that automatically adjusts the capacity of multiple AWS resources to match current demand. Unlike EC2 Auto Scaling, AWS Auto Scaling works across EC2, ECS, DynamoDB, Aurora, and other services.
What does AWS Auto Scaling cost?
AWS Auto Scaling itself is free. You only pay for the AWS resources that are provisioned by the scaling policies.
How does AWS Auto Scaling differ from EC2 Auto Scaling?
EC2 Auto Scaling only scales EC2 instances. AWS Auto Scaling provides a unified interface to define scaling policies for multiple services simultaneously, including EC2, ECS, DynamoDB, and Aurora.
