Secure Web App with Automation, Containerization, Backups, and GitOps

1. Launch an EC2 Instance

✅ Firewall management starts here.

1. Ubuntu 22.04 or Amazon Linux 2.
• More Details
2. Create a Security Group → Allow only ports 22 (SSH), 80 (HTTP), and 443 (HTTPS).

• Uploads backups to AWS S3 bucket automatically
2. Schedule it with a cron job (cron) to run every Monday @ 2 AM
• More Details

5. Infrastructure as Code (IaC)

✅ Cloud automation + DevOps.

Write a Terraform script to:

• ☁️ Create the EC2 instance
• 🔒 Set up Security Groups
• 📌 Attach an Elastic IP (EIP)

6. Monitoring

✅ Security and Monitoring.

• 🛡️ Install fail2ban to prevent brute-force SSH attacks
• 📋 Set up basic logging using CloudWatch Agent
• 📊 Monitor uptime and disk space

Create a README.md for GitHub project

• Setup Instructions
• Architecture Diagram
• Backup/Restore Strategy
• Rebuild from Scratch
