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.
AWS Cloud Map lets you define simple 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 any other cloud resource.
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.
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.
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.
Services and tasks managed by Amazon Elastic Container Service (ECS) or Amazon Elastic Service for Kubernetes (EKS) can be automatically registered and updated in Cloud Map. As ECS launches tasks for your service, it automatically registers them as resources with Cloud Map, and they are discoverable within five seconds.
When you are using API-based discovery, the updates on your resource locations and attributes are available within 5 seconds.
AWS Cloud Map eliminates the need to set up, update, and manage your own service discovery tools and software.
