AWS health check and management

Question

I want to create a health check script to deploy on my VM, that I'll call over HTTP. After receiving the result of the script(say n number of failures) I'd want to stop and delete the VMs and then replace by some autoscaling group or create a replacement instance for the same. How should I go about achieving this?

Answer 1

You can use Application Loadbalancer or AWS Classic Loadbalancer to perform health checks via http. Then you can use an auto scaler to use healthcheck for the load balancer. That way if a helathcheck states something unhealthy it will be replaced by the auto scaling group. You need to provide http endpoint which, if  the app is healthy return 200.
