Welcome - Amazon EC2 Auto Scaling

Welcome

This is the Amazon EC2 Auto Scaling API Reference. Amazon EC2 Auto Scaling is designed to automatically launch or terminate EC2 instances based on user-defined scaling policies, scheduled actions, and health checks.

The documentation for each action shows the Query API request syntax, the request parameters, and the XML response.

As an alternative to the API, you can use one of the AWS SDKs, which consist of libraries and sample code for various programming languages and platforms. The SDKs provide a convenient way to create programmatic access to Amazon EC2 Auto Scaling. For example, the SDKs take care of cryptographically signing requests, managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see the Tools for Amazon Web Services page.

For more information about Amazon EC2 Auto Scaling, see the Amazon EC2 Auto Scaling User Guide. For information about granting IAM users required permissions for calls to the Amazon EC2 Auto Scaling API, see Granting IAM users required permissions for Amazon EC2 Auto Scaling resources.
