I am so glad that you liked it :) thanks for your support!

Glad you liked it :) thanks!

Hi Hitesh, If the application code changes, I would assume the underlying image would change. So, you might need to patch the AMI and update the ASG, more details here - docs.aws.amazon.com/systems-manager/latest/userguide/automation-walk-patch-windows-ami-autoscaling.html Otherwise, you can try using a combination of CodeDeploy and ASG, more details here - docs.aws.amazon.com/codedeploy/latest/userguide/integrations-aws-auto-scaling.html Please let me know if you are looking to handle a different scenario.

Hi Ruchi, If you have more than one security group attached to your VM, the union of all the rules from each security group will be applied to the VM. So, it should be ok to add the rule in just one security group.

Could you please check the below settings - 1. The security group associated with the servers allows port 80 access from LB security group 2. The security group associated with the LB allows port 80 access from 0.0.0.0 3. The NAT gateway and Internet gateways are attached to the private and public subnets respectively 4. The health checks are configured correctly with appropriate settings as shown 5. The server has executed the user data script and configured correctly.
