// Public DNS and HTTP namespaces only. A complex type that contains settings

// If you specify a health check configuration, you can specify either HealthCheckCustomConfig

//
// Health checks are basic Route 53 health checks that monitor an AWS endpoint.
// For information about pricing for health checks, see Amazon Route 53 Pricing
// (http://aws.amazon.com/route53/pricing/).
//
// Note the following about configuring health checks.
//
// A and AAAA records
//
// If DnsConfig includes configurations for both A and AAAA records, AWS Cloud
// Map creates a health check that uses the IPv4 address to check the health
// of the resource. If the endpoint that is specified by the IPv4 address is
// unhealthy, Route 53 considers both the A and AAAA records to be unhealthy.
//
// CNAME records
//
// You can't specify settings for HealthCheckConfig when the DNSConfig includes
// CNAME for the value of Type. If you do, the CreateService request will fail
// with an InvalidInput error.
//
// Request interval
//
// A Route 53 health checker in each health-checking region sends a health check
// request to an endpoint every 30 seconds. On average, your endpoint receives
// a health check request about every two seconds. However, health checkers
// don't coordinate with one another, so you'll sometimes see several requests
// per second followed by a few seconds with no health checks at all.
//
// Health checking regions
//
// Health checkers perform checks from all Route 53 health-checking regions.
// For a list of the current regions, see Regions (https://docs.aws.amazon.com/Route53/latest/APIReference/API_HealthCheckConfig.html#Route53-Type-HealthCheckConfig-Regions).
//
// Alias records
//
// When you register an instance, if you include the AWS_ALIAS_DNS_NAME attribute,
// AWS Cloud Map creates a Route 53 alias record. Note the following:
//
//    * Route 53 automatically sets EvaluateTargetHealth to true for alias records.
//    When EvaluateTargetHealth is true, the alias record inherits the health
//    of the referenced AWS resource. such as an ELB load balancer. For more
//    information, see EvaluateTargetHealth (https://docs.aws.amazon.com/Route53/latest/APIReference/API_AliasTarget.html#Route53-Type-AliasTarget-EvaluateTargetHealth).
//
//    * If you include HealthCheckConfig and then use the service to register
//    an instance that creates an alias record, Route 53 doesn't create the
//    health check.
//
// Charges for health checks

	//    * You can't use a health check that is defined by HealthCheckConfig because
	//    the resource isn't available over the internet. For example, you can use
	//    a custom health check when the instance is in an Amazon VPC. (To check
	//    the health of resources in a VPC, the health checker must also be in the
	//    VPC.)
	//
	//    * You want to use a third-party health checker regardless of where your
	//    resources are.
	//
	// If you specify a health check configuration, you can specify either HealthCheckCustomConfig
	// or HealthCheckConfig but not both.
	//
	// To change the status of a custom health check, submit an UpdateInstanceCustomHealthStatus
	// request. AWS Cloud Map doesn't monitor the status of the resource, it just
	// keeps a record of the status specified in the most recent UpdateInstanceCustomHealthStatus
	// request.
	//
	// Here's how custom health checks work:
	//
	// You create a service and specify a value for FailureThreshold.
	//
	// The failure threshold indicates the number of 30-second intervals you want
	// AWS Cloud Map to wait between the time that your application sends an UpdateInstanceCustomHealthStatus
	// (https://docs.aws.amazon.com/cloud-map/latest/api/API_UpdateInstanceCustomHealthStatus.html)
	// request and the time that AWS Cloud Map stops routing internet traffic to
	// the corresponding resource.
	//
	// You register an instance.
	//
	// You configure a third-party health checker to monitor the resource that is
	// associated with the new instance.
	//
	// AWS Cloud Map doesn't check the health of the resource directly.
	//
	// The third-party health-checker determines that the resource is unhealthy
	// and notifies your application.
	//
	// Your application submits an UpdateInstanceCustomHealthStatus request.
	//
	// AWS Cloud Map waits for (FailureThreshold x 30) seconds.
	//
	// If another UpdateInstanceCustomHealthStatus request doesn't arrive during
	// that time to change the status back to healthy, AWS Cloud Map stops routing
	// traffic to the resource.
