AWS Command Line Interface (CLI)

The AWS Command Line Interface (CLI) tool allows developers to control Amazon public cloud services by typing commands on a specific line.

The AWS Command Line Interface (CLI) is a centralized management tool for your AWS services. Multiple AWS services can be downloaded and configured using this tool. It also allows you to control and automate various AWS services.

Using this tool, you can manage and control all AWS services. To automate the management of AWS infrastructure resources and services, you can also use the CLI.

AWS’ command-line interface is among several ways a developer can develop and manage AWS tools. AWS Management Console and AWS application programming interfaces are two other options. A developer may prefer the AWS CLI over other techniques because it provides more precise control over other services. And it also allows for script automation.
