• Created a Target Group and registered EC2 instances.
• Configured a listener on HTTP : 80.
• Result: Load‑balanced traffic across servers.

🔁 Step 4 — Auto Scaling Group (Self Healing)

• Configured Auto Scaling with Min = 1.
• Tested self‑healing by manually terminating instances; AWS automatically launched new servers.

📊 Step 5 — CloudWatch Monitoring

• Created alarms on CPU Utilization

❤️ What I Learned
