==========
AWS CLI 
==========

=> AWS provides multiple ways to configure and manage infrastructure

=> We can use below 4 ways to manage AWS infrastructure

	1) AWS Management Web Console (browser)

	2) AWS CLI (Command Line Interface)

	3) Cloud Formation

	4) Terraform

===========================
Using the AWS web console
===========================

=> It is a graphical user interface to connect with various AWS resources, their configuration, modification, etc. 

=> It is very simple to use and does not require knowledge of scripting.

============================
AWS Command Line Interface
============================

=> Using AWS CLI we can manage infrastructure in AWS cloud using commands

Ex : 

$ aws s3 ls

$ aws ec2 describe-instances

============================
Configuring AWS CLI
============================

1) Login into AWS account & generate access keys

	Access Key : AKIAQE43J7YYMPAZMYMT
	Secret Access key : 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

Note: Not recommended to use root user access keys.	

2) Download and Install AWS CLI s/w

	For windows : https://awscli.amazonaws.com/AWSCLIV2.msi

3) Configure AWS CLI

	$ aws --version

	$ aws configure	

Note: AWS configure command will ask for access key, secret access key, region and output format.
