The AWS CLI is a powerful tool for managing your AWS services and resources from a terminal session. It was built on top of the AWS API, and hence everything that can be done through the AWS Management Console can be done with the CLI; this makes it a handy tool that can be used to automate and control your AWS infrastructure through scripts. Later chapters will provide information on the use of the CLI to manage Lambda functions and create other AWS services around Lambda.
Let's go through the installation process for the AWS CLI; you can find information on its configuration and testing in the AWS Management Console section.
