Set up to use Amazon EC2 Auto Scaling
Before you start using Amazon EC2 Auto Scaling, complete the following tasks.
Prepare to use Amazon EC2
If you haven't used Amazon EC2 before, complete the tasks described in the Amazon EC2 documentation. For more information, see Setting up with Amazon EC2 in the Amazon EC2 User Guide or Setting up with Amazon EC2 in the Amazon EC2 User Guide.
Prepare to use the AWS CLI
You can use the AWS command line tools to issue commands at your system's command line to perform Amazon EC2 Auto Scaling and other AWS tasks.
To use the AWS Command Line Interface (AWS CLI), download, install, and configure version 1 or 2 of the AWS CLI. The same Amazon EC2 Auto Scaling functionality is available in version 1 and 2. To install the AWS CLI version 1, see Installing, updating, and uninstalling the AWS CLI in the AWS CLI Version 1 User Guide. To install the AWS CLI version 2, see Installing or updating the latest version of the AWS CLI in the AWS CLI Version 2 User Guide.
AWS CloudShell lets you skip installing the AWS CLI in your development environment, and use it in the AWS Management Console instead. In addition to avoiding installation, you also don't need to configure credentials, and you don't need to specify a region. Your AWS Management Console session provides this context to the AWS CLI. You can use AWS CloudShell in supported AWS Regions. For more information, see Create Auto Scaling groups from the command line using AWS CloudShell.
For more information, see autoscaling in the AWS CLI Command Reference.
