AWS Week-9 Assignment: Web Application Deployment

This project showcases the deployment of a static web application using AWS services:

• Amazon S3 for hosting static assets (HTML + images)
• Auto Scaling Group (ASG) to manage EC2 instances
• Application Load Balancer (ALB) for distributing incoming traffic
• Launch Template with User Data script for EC2 setup

---

🔧 Deployment Overview

• Created an S3 bucket: nawal-clarusway-assets
• Uploaded:
  • index.html
  • logo.png
  • sda.png
• Enabled Static Website Hosting and configured a public read Bucket Policy.
• Built a Launch Template installing NGINX and pulling assets from S3.
• Configured an Auto Scaling Group:
  • Desired: 2
  • Min: 1
  • Max: 3
• Set up an internet-facing ALB listening on port 80 and attached the Target Group: clarusway-tg.

🐞 Issue Encountered: Missing Images (logo.png and sda.png)

After initial deployment, the main HTML page loaded successfully, but the logo images did not appear.

🧪 Root Cause:

• EC2 instances lacked permissions to access the S3 bucket.
• User Data tried to copy assets from S3 but failed silently.

---

✅ Solution:

1. Created an IAM Role with AmazonS3ReadOnlyAccess.

2. Attached the role to EC2 instances via Modify IAM Role option.

3. Manually copied the assets:

   sudo aws s3 cp s3://nawal-clarusway-assets/index.html /usr/share/nginx/html/
   sudo aws s3 cp s3://nawal-clarusway-assets/logo.png /usr/share/nginx/html/
   sudo aws s3 cp s3://nawal-clarusway-assets/sda.png /usr/share/nginx/html/

Ensured correct file names in index.html (e.g., logo.png, sda.png).

Verified via ALB endpoint — All logos displayed successfully.

🖼️ Final Results Website accessible via:

S3 Static Website Endpoint (for static assets)

ALB DNS Name (dynamic serving via ASG)

All assets (HTML + logos) are loading properly on both paths.
