// For information about adding health checks to resource record sets, see HealthCheckId
// (https://docs.aws.amazon.com/Route53/latest/APIReference/API_ResourceRecordSet.html#Route53-Type-ResourceRecordSet-HealthCheckId)

//
// ELB Load Balancers
//
// If you're registering EC2 instances with an Elastic Load Balancing (ELB)
// load balancer, do not create Amazon Route 53 health checks for the EC2 instances.
// When you register an EC2 instance with a load balancer, you configure settings
// for an ELB health check, which performs a similar function to a Route 53
// health check.
//
// Private Hosted Zones
//
// You can associate health checks with failover resource record sets in a private
// hosted zone. Note the following:
//
//    * Route 53 health checkers are outside the VPC. To check the health of
//    an endpoint within a VPC by IP address, you must assign a public IP address
//    to the instance in the VPC.
//
//    * You can configure a health checker to check the health of an external
//    resource that the instance relies on, such as a database server.
//
//    * You can create a CloudWatch metric, associate an alarm with the metric,
//    and then create a health check that is based on the state of the alarm.
//    For example, you might create a CloudWatch metric that checks the status
//    of the Amazon EC2 StatusCheckFailed metric, add an alarm to the metric,
//    and then create a health check that is based on the state of the alarm.
//    For information about creating CloudWatch metrics and alarms by using
//    the CloudWatch console, see the Amazon CloudWatch User Guide (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/WhatIsCloudWatch.html).
