// Creates a new health check.
//
// For information about adding health checks to resource record sets, see [HealthCheckId] in [ChangeResourceRecordSets].
//
// # 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].
