• Deploy an Application Load Balancer using boto3.
• Register the EC2 instance(s) with the ALB.

3. Auto Scaling Group (ASG) Configuration:

• Configure scaling policies based on metrics (e.g., CPU, network).

4. Lambda-based Health Checks & Management:

• Develop a Lambda function for health checks via ALB.
• Implement actions for consistent failures: snapshot, terminate, notify.

5. S3 Logging & Monitoring:

• Configure ALB to send access logs to the S3 bucket.
• Create a monitoring Lambda for log analysis & alerts.

6. SNS Notifications:

• Set up SNS topics for various alerts.
• Integrate SNS with Lambda for admin notifications.
