#dns_records ⇒ Array<Types::DnsRecord>

An array that contains one ‘DnsRecord` object for each Route 53 DNS record that you want Cloud Map to create when you register an instance.

The record type of a service specified in a ‘DnsRecord` object can’t be updated. To change a record type, you need to delete the service and recreate it with a new ‘DnsConfig`.

end

#routing_policy ⇒ String

The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service.

<note markdown=“1”> If you want to use this service to register instances that create alias records, specify ‘WEIGHTED` for the routing policy.

</note>

You can specify the following values:

MULTIVALUE

: If you define a health check for the service and the health check

is healthy, Route 53 returns the applicable value for up to eight
instances.

For example, suppose that the service includes configurations for
one `A` record and a health check. You use the service to register
10 instances. Route 53 responds to DNS queries with IP addresses
for up to eight healthy instances. If fewer than eight instances
are healthy, Route 53 responds to every DNS query with the IP
addresses for all of the healthy instances.

If you don't define a health check for the service, Route 53
assumes that all instances are healthy and returns the values for
up to eight instances.

For more information about the multivalue routing policy, see
[Multivalue Answer Routing][1] in the *Route 53 Developer Guide*.

WEIGHTED

: Route 53 returns the applicable value from one randomly selected

instance from among the instances that you registered using the
same service. Currently, all records have the same weight, so you
can't route more or less traffic to any instances.

For example, suppose that the service includes configurations for
one `A` record and a health check. You use the service to register
10 instances. Route 53 responds to DNS queries with the IP address
for one randomly selected instance from among the healthy
instances. If no instances are healthy, Route 53 responds to DNS
queries as if all of the instances were healthy.

If you don't define a health check for the service, Route 53
assumes that all instances are healthy and returns the applicable
value for one randomly selected instance.

For more information about the weighted routing policy, see
[Weighted Routing][2] in the *Route 53 Developer Guide*.
