AWS Cloud Map
API Reference (API Version 2017-03-14)


Submits a request to perform the following operations:

  • Add or delete DnsRecords configurations

  • Update the TTL setting for existing DnsRecords configurations

  • Add, update, or delete HealthCheckConfig for a specified service

For public and private DNS namespaces, you must specify all DnsRecords configurations (and, optionally, HealthCheckConfig) that you want to appear in the updated service. Any current configurations that don't appear in an UpdateService request are deleted.

When you update the TTL setting for a service, AWS Cloud Map also updates the corresponding settings in all the records and health checks that were created by using the specified service.
