- What is AWS CLI?

AWS CLI happens to be a unified tool used for managing and monitoring the AWS services right from the command line on the client's desktop.

We can manage all 175 services through the AWS Management Console or via the APIs. However, there is one more way to do this, and it's the best among all the options available. It's the AWS CLI. No matter whether you are on Linux, Windows, or macOS, you can manage all the AWS services from the local terminal sessions command line. Hence, through a one-step installation and the least configuration, you can make use of the functionalities which are provided by the AWS Management Console via the terminal program. And that can be a Linux shell like bash, tsch, or zsh for running the commands on various operating systems like Linux, macOS, or Unix or Windows command line using PowerShell or in the Windows command prompt.

You can also run the commands using the Amazon EC2 instances via the remote terminal, like PuTTY or SSH. You can also use the AWS systems manager for automating the operational tasks over the AWS resources.

Also, you get direct access to "AWS services public APIs." So, you can make use of the low-level API equivalent commands. However, the AWS CLI offers customization for various services.

Let's discuss them all in this article.

- Uses of AWS CLI

Below are some of the reasons enough to get you started with the AWS CLI.

1.??????Very Easy to Install

Before AWS came up with the AWS CLI, the old AWS API-like toolkits requires complex steps. We have to provide a lot of environmental variables. However, the installation of the AWS command-line interface has changed the whole complexion. It's quite simple, quick, and standardized.

It saves time, as using the AWS management console can be quite tedious at times. Like suppose you need to find an image in the Amazon S3 folder via the management console, you need to search for the correct S3 bucket, then search for the right folder, and then the image you are searching for in the folder. However, through the AWS CLI, you need to remember the command as per the tasks, and then it takes a few seconds to execute.

2.??????Automates Processes

Via the AWS CLI, you can automate the entire procedure of management and control of the AWS services via the scripts. And these scripts make it simple for the user to automate the cloud infrastructure.

3.??????AWS CLI Supports all AWS services

Almost all the AWS services support the AWS CLI. And when a new service is released, they come with CLI support or with the assurance of CLI support in less than 180 days of release.

4.??????Management Console supports not all features of AWS

It's a fact that some features of AWS do not work through the management console, and in that case, you need the AWS CLI.

Hence, now it's clear that AWS CLI is essential and all serious programmers should make use of the AWS CLI, Let's see how we can install it.

-Configure AWS CLI

For configuring the AWS CLI, we need to make use of the below command.

Remember, you will get the secret access key at the time you will create the user. You need to keep it at some safe location, or else you will have to recreate the user if you lose it. You can select the region as per your requirement. Also, there are three output formats JSON, text, and table. You can make a selection among these.

And as you will make use of the above command, the AWS CLI is going to ask you for all this information. Only the first two are a must. Other, you can leave it as default.
