Set up 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 for Linux Instances or Setting up with Amazon EC2 in the Amazon EC2 User Guide for Windows Instances.
Prepare to use the Amazon CLI
You can use the Amazon command line tools to issue commands at your system's command line to perform Amazon EC2 Auto Scaling and other Amazon tasks.
To use the Amazon Command Line Interface (Amazon CLI), download, install, and configure version 1 or 2 of the Amazon CLI. The same Amazon EC2 Auto Scaling functionality is available in version 1 and 2. To install the Amazon CLI version 1, see Installing, updating, and uninstalling the Amazon CLI in the Amazon CLI Version 1 User Guide. To install the Amazon CLI version 2, see Installing or updating the latest version of the Amazon CLI in the Amazon CLI Version 2 User Guide.
Amazon CloudShell lets you skip installing the Amazon CLI in your development environment, and use it in the Amazon Web Services 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 Amazon Web Services Management Console session provides this context to the Amazon CLI. You can use Amazon CloudShell in supported Amazon Web Services Regions. For more information, see Create Auto Scaling groups from the command line using Amazon CloudShell.
For more information, see autoscaling in the Amazon CLI Command Reference.
