Cloud Map allows your applications to discover any web-based service via AWS SDK, API calls, or DNS queries. Over DNS, Cloud Map provides resource locations of IP addresses or IP:port combinations using either IPv4 or IPv6. Using the discovery API, Cloud Map can return URLs or ARNs as well as IP addresses and IP:port combinations.
Cloud Map lets you define custom attributes for each resource, such as location and deployment stage. This provides you the ability to customize your deployment across different regions or environments.
Access control
Cloud Map is integrated with AWS Identity and Access Management (IAM) to ensure that only authenticated services can discover resources within the registry and retrieve the location and credential for those resources.
Automatic health check
Amazon Route 53 health checks ensure that only healthy endpoints are returned on discovery queries. This ensures that Cloud Map always has an up-to-date registry of healthy resources.
