Introduction:

AWS CLI (Command Line Interface) is a powerful tool that allows users to interact with Amazon Web Services through a command-line interface. It provides a set of commands for controlling AWS services, managing resources, and automating tasks. With AWS CLI, users can efficiently navigate and manipulate various AWS functionalities directly from the command line, streamlining the management of cloud resources. Whether you're a developer, system administrator, or DevOps professional, AWS CLI offers a flexible and efficient way to work with AWS services in a text-based environment.
