Complete Hands-On Guide: Upload, Download, and Delete Files in Amazon S3 Using EC2 IAM Roles  

Are you looking for a secure and efficient way to manage files in Amazon S3 using an EC2 instance? This step-by-step tutorial will teach you how to upload, download, and delete files in Amazon S3 using IAM roles for secure access. Say goodbye to hardcoding AWS credentials and embrace best practices for security and scalability.  

What You'll Learn in This Video:  

1. Understanding IAM Roles for EC2:     - What are IAM roles?     - Why should you use IAM roles instead of hardcoding access keys?     - How to create and attach an IAM role with S3 permissions to your EC2 instance.  

2. Configuring the EC2 Instance for S3 Access:     - Launching an EC2 instance and attaching the IAM role.     - Setting up the AWS CLI on your EC2 instance.  

3. Uploading Files to S3:     - Step-by-step commands to upload files to an S3 bucket.     - Use cases for uploading files, such as backups or log storage.  

4. Downloading Files from S3:     - Retrieving objects stored in your S3 bucket using AWS CLI.     - How to test and verify successful downloads.  

5. Deleting Files in S3:     - Securely deleting files from an S3 bucket.     - Use cases like removing outdated logs or freeing up storage.  

6. Best Practices for S3 Operations:     - Using least privilege policies in IAM roles.     - Encrypting files in transit and at rest.     - Monitoring and logging using AWS CloudTrail and S3 access logs.  

Why IAM Roles Are Essential for S3 Operations:   - Secure Access: IAM roles provide temporary credentials, eliminating the risk of hardcoding secrets in your scripts.   - Automation-Friendly: Simplify file operations for DevOps workflows and automation scripts.   - Centralized Management: Control and modify permissions from a single IAM role without touching your instance.  

Real-World Applications of This Tutorial:   - Automating log uploads from EC2 to S3 for centralized storage.   - Downloading data files or software packages hosted in S3 for application use.   - Removing outdated or unnecessary files to optimize your S3 bucket storage.  

AWS Services and Tools Covered in This Tutorial:   - Amazon S3: Scalable object storage for uploading, downloading, and deleting files.   - Amazon EC2: Virtual servers in the cloud for running scripts and applications.   - AWS IAM Roles: Secure and temporary permissions for accessing S3.   - AWS CLI: Command-line tool for managing AWS services.  

Hands-On Process:   1. Step 1: Create an S3 Bucket     - Navigate to the S3 console and create a new bucket with a unique name.     - Configure bucket permissions for private or public access as needed.  

2. Step 2: Configure IAM Role     - Create an IAM role with an S3 access policy.     - Attach the role to your EC2 instance to avoid hardcoding credentials.  

3. Step 3: Launch and Connect to an EC2 Instance     - Launch an EC2 instance with the IAM role attached.     - Connect to the instance using SSH.  

4. Step 4: Install AWS CLI and Configure     - Install AWS CLI on the EC2 instance if not pre-installed.     - Verify access by running `aws s3 ls` to list available buckets.  

5. Step 5: Perform File Operations     - Upload files: Use `aws s3 cp` to upload a file from EC2 to S3.     - Download files: Use `aws s3 cp` to download files from S3 to EC2.     - Delete files: Use `aws s3 rm` to delete a file from the S3 bucket.  

6. Step 6: Cleanup     - Delete test files and terminate resources to avoid unnecessary charges.
