Health Check

This feature is check only for public resources. It can monotor via the Endpoint or CloudWatch.

For Health check endpoint , It pass only when then endpoint responds with the 2xx and 3xx status code. Also we need to allow ALB or other resources to grant the access for Route 53 . Another thing we can also have Parent Health check to determine the overall health check status example

If we have 3 health check for each resource and one parent health check then the parent health check will be passed when 2 of 2 health check is alive.
