Amazon EC2 Auto Scaling

Add or remove compute capacity to meet changing demand

Why Amazon EC2 Auto Scaling?

Amazon EC2 Auto Scaling helps you maintain application availability and lets you automatically add or remove EC2 instances using scaling policies that you define. Dynamic or predictive scaling policies let you add or remove EC2 instance capacity to service established or real-time demand patterns. The fleet management features of Amazon EC2 Auto Scaling help maintain the health and availability of your fleet.


Improve fault tolerance through automatic detection and replacement of unhealthy instances.
Increase availability with predictive or dynamic scaling policies with the right amount of compute capacity.
Optimize workload performance and cost by combining purchase options and instance types.
Reduce the complexity of configuration changes and application deployments with instance refresh.

Use cases

Use previous traffic patterns to determine application scaling in advance of known load changes.

Follow the demand curve for your applications so that you don’t have to provision Amazon EC2 capacity in advance.

Use machine learning to predict and schedule the right number of EC2 instances to anticipate approaching traffic changes.
