# Mastering AWS S3 and AWS CLI: A Practical Guide 🚀

Hello Hashnode Community! 👋 Today, I'm thrilled to share practical insights from my recent deep dive into Amazon S3 and the AWS CLI as part of the #90DaysofDevOps Challenge. Let's jump right into the key steps and discoveries!

## Task-01: Seamless EC2 and S3 Integration

### Setting Up EC2 and S3

1. **EC2 Instance Launch:**
    
    * Initiated an EC2 instance via the AWS Management Console.

    * Ensured secure access through SSH.
        
2. **S3 Bucket Creation and File Upload:**
    
    * Crafted an S3 bucket, ensuring proper naming conventions.

    * Directly uploaded a file using the AWS Management Console.
        
3. **AWS CLI in Action:**
    
    * Leveraged the AWS CLI to access the S3 file from the EC2 instance programmatically.
        
    * Ran `aws s3 cp s3://your-bucket-name/your-file.txt .` for seamless download.

## Task-02: Snapshot, EC2 Redux, and Advanced S3 Interaction

### Snapshot Chronicles and Advanced S3 Operations

1. **Creating EC2 Snapshot:**
    
    * Captured a snapshot of the EC2 instance for future replication.
        
2. **New EC2 from Snapshot:**
    
    * Launched a new EC2 instance using the created snapshot.
        
3. **AWS CLI for S3 Operations:**
    
    * Demonstrated AWS CLI commands for downloading S3 files.
        
    * Validated file consistency across different EC2 instances.
        

*Include Screenshot: AWS CLI commands for snapshot creation and S3 file download.*
