Amazon Cloud Map namespaces

A namespace is a logical entity in Amazon Cloud Map that is used to group an application's services under a common name and level of discoverability. When you create a namespace, you specify the following:

  • A name that you want your application to use to discover instances.

  • The method by which service instances that you register with Amazon Cloud Map can be discovered. You can decide whether your resources need to be discovered publicly over the internet, privately in a specific virtual private cloud (VPC), or by API calls only.

The following are general concepts about namespaces.

  • Namespaces are specific to the Amazon Web Services Region that they're created in. To use Amazon Cloud Map in multiple regions, you'll need to create namespaces in each region.

  • If you create a namespace to allow for instance discovery by DNS queries in a VPC, Amazon Cloud Map automatically creates a private Route 53 hosted zone. This hosted zone can be associated with multiple VPCs. For more information, see AssociateVPCWithHostedZone in the Amazon Route 53 API Reference.
