Uses of AWS S3 Bucket
Backup and Disaster Recovery
AWS S3 bucket is an excellent choice for backing up data and creating disaster recovery solutions. You can replicate data across multiple regions and availability zones to ensure that your data remains safe and available.
Website Hosting
S3 can host static websites and serve static assets like images, videos, and CSS files. You can use Amazon CloudFront to serve dynamic content and improve website performance.
Data Lake
AWS S3 bucket can act as a data lake, which means that you can store all your data in a centralized location and analyze it using various AWS analytics services like Amazon Athena, Amazon EMR, Amazon Redshift, etc.
Media Storage and Distribution

Steps to setup AWS CLI on Linux system
To interact with an S3 bucket from the command line interface (CLI), we can use the AWS CLI tool.
Install the AWS CLI using the appropriate package manager for your Linux distribution. For example, on Ubuntu, you can use the following command:
sudo apt-get install awscli
By using this command you can verify that AWS CLI is correctly installed in your system.
aws --version
This command will display the version number of the AWS CLI of your system.
Configure the AWS CLI by running the following command:
aws configure
After this, You will be prompted to enter your AWS access key ID, secret access key, default region name, and default output format. You can obtain your access key ID and secret access key from the AWS Management Console.
Once you have configured the AWS CLI, you can start using it to interact with AWS services from the command line.
Commands to Run S3 Bucket in AWS CLI
Once you have configured the AWS CLI in your local machine, you can use the following command to list all of the S3 buckets in your AWS account:
aws s3 ls
To create a new S3 bucket, use the following command:
aws s3 mb s3://bucket-name
you can give any name in the place of bucket name.
To upload a file to your S3 bucket, use the following command:
aws s3 cp /path/to/local/file s3://bucket-name
Replace /path/to/local/file with the path to the file on your local machine that you want to upload.
To download a file from your S3 bucket, use the following command:
aws s3 cp s3://bucket-name/path/to/file /path/to/local/destination
Replace path/to/file with the path to the file in your S3 bucket that you want to download, and /path/to/local/destination with the path on your local machine where you want to save the downloaded file.
