CreatePrivateDnsNamespace - AWS Cloud Map


Creates a private namespace based on DNS, which is visible only inside a specified Amazon VPC. The namespace defines your service naming scheme. For example, if you name your namespace and name your service backend, the resulting DNS name for the service is Service instances that are registered using a private DNS namespace can be discovered using either a DiscoverInstances request or using DNS. For the current quota on the number of namespaces that you can create using the same AWS account, see AWS Cloud Map quotas in the AWS Cloud Map Developer Guide.
