AWS Cloud Map Documentation

Discover resources via API calls or DNS queries

Cloud Map allows your applications to discover web-based services 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.

Simplified service naming

AWS Cloud Map lets you define custom names for services in your application. This can include Amazon Elastic Container Service (ECS) tasks, Amazon EC2 instances, Amazon S3 buckets, Amazon DynamoDB tables, Amazon Simple Queue Service (SQS) queues, and other cloud resources.

Assign custom attributes

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), which is designed so that only authenticated services can discover resources within the registry and retrieve the location and credential for those resources.

Health check

Amazon Route 53 health checks are designed so that healthy endpoints are returned on discovery queries. 

Integration with AWS container services

Services and tasks managed by Amazon Elastic Container Service (ECS) or Amazon Elastic Service for Kubernetes (EKS) can be registered and updated in Cloud Map. As ECS launches tasks for your service, it registers them as resources with Cloud Map, making them discoverable.

Rapid change propagation

The updates on your resource locations and attributes are available when using API-based discovery.

Managed Service

AWS Cloud Map reduces the need to set up, update, and manage your own service discovery tools and software.
