✅ Day 10 of My Cloud Journey ☁ – Hands-on with Amazon S3 using AWS CLI on EC2 💻🪣

Today I rolled up my sleeves and got practical with one of the most valuable cloud combinations: Amazon EC2 + S3 + AWS CLI. This is where you start seeing how DevOps, automation, and cloud-native development come together in real workflows.

🔍 What Was Today All About?

While the AWS Console is beginner-friendly and visual, the AWS CLI (Command Line Interface) offers powerful automation and scripting capabilities — vital for production-grade environments.

Today, I connected to a running EC2 instance and used the AWS CLI to:

• Create an S3 bucket

• Upload/download files

• Securely manage permissions with IAM Roles

• Automate storage operations from the terminal

🛠️ What I Did (Hands-On Steps):

1️⃣ Launched an EC2 Instance using Amazon Linux 2023
2️⃣ SSH Access to connect securely via terminal
3️⃣ Installed the AWS CLI (already pre-installed on Amazon Linux)
4️⃣ Configured credentials using aws configure (for test/demo only)
5️⃣ Created a new S3 bucket directly from the terminal
6️⃣ Uploaded and downloaded files
7️⃣ Tested IAM Role-based Access without needing access keys 🎯

💻 CLI Commands I Practiced

Here's a cheat sheet of the AWS CLI commands I used:

bashCopyEditaws s3 mb s3://my-bucket-name             # Create a bucket
aws s3 ls                                 # List all buckets
aws s3 cp myfile.txt s3://my-bucket-name # Upload a file
aws s3 ls s3://my-bucket-name            # List contents of the bucket
aws s3 cp s3://my-bucket-name/myfile.txt . # Download the file
aws s3 rm s3://my-bucket-name/myfile.txt # Delete the file

🔐 IAM Roles vs. AWS Configure

📌 Key Learning: IAM Roles eliminate the need to store credentials in code or config — a major win for security-first cloud architectures.

---

🧠 What I Learned

✅ How EC2 and S3 work together seamlessly
✅ CLI operations are much faster and perfect for automation
✅ IAM Roles allow secure, credential-free access to services
✅ CLI is essential for DevOps tasks, backups, deployments, and more

🌍 Real-World Use Cases

🔹 Automate logs or reports upload to S3
🔹 Backup critical files from EC2 to S3
🔹 Lambda/EC2 fetching config/data from S3 at runtime
🔹 Trigger events when objects are uploaded (using S3 events + Lambda)
🔹 Build cron jobs for automated sync between local storage and S3

---

🧩 Recap: Why AWS CLI Matters in Cloud Workflows

• Works consistently across platforms (Linux, macOS, Windows)

• Enables scripting & automation

• Faster than Console for bulk or repeated tasks

• Easily integrates into CI/CD pipelines, Bash scripts, and cron jobs

• Reduces error-prone manual processes.

📅 What’s Next?

🔁 Tomorrow – Day 11:
We’ll shift gears from storage to networking as I dive into Amazon VPC (Virtual Private Cloud) and explore:

• 🔹 What is a VPC?

• 🔹 Subnets (Public vs. Private)

• 🔹 Internet Gateway (IGW)

• 🔹 NAT Gateway

• 🔹 Route Tables and how traffic flows in AWS

Understanding VPC is crucial for deploying secure and scalable cloud applications — don’t miss it! 🧠🌐
