AWS Cloud Map Enhances Service Discovery with Cross-Account Support
Amazon Web Services (AWS) is pleased to announce a significant enhancement to AWS Cloud Map, its fully managed service discovery service. Effective August 14, 2025, AWS Cloud Map now offers support for cross-account service discovery, empowering customers to seamlessly discover and connect services deployed across multiple AWS accounts. This new capability marks a pivotal step forward in simplifying the management of distributed applications and microservices architectures.
Previously, AWS Cloud Map was primarily designed for service discovery within a single AWS account. While effective for many use cases, organizations with complex, multi-account environments often faced challenges in enabling services in one account to discover and communicate with services in another. This necessitated the implementation of custom solutions or workarounds, adding operational overhead and complexity.
The introduction of cross-account service discovery directly addresses this need. With this update, you can now register your services in AWS Cloud Map and make them discoverable by principals (users, roles, or services) in different AWS accounts. This facilitates a more unified and streamlined approach to managing and accessing services, regardless of their account placement.
Key Benefits and Use Cases:
The new cross-account capabilities of AWS Cloud Map unlock a range of powerful benefits and open up new possibilities for your cloud deployments:
-
Simplified Microservices Communication: For organizations adopting a microservices architecture spread across multiple AWS accounts (e.g., for organizational separation, compliance, or different development teams), this feature enables seamless inter-service communication. Services can discover and connect to each other without complex networking configurations or manual endpoint management.
-
Enhanced Collaboration and Shared Services: This feature is invaluable for scenarios where different teams or business units manage their services in separate accounts but need to consume shared services (e.g., a central authentication service, a logging aggregation service, or a data analytics platform). Cross-account discovery allows these shared services to be easily located and utilized by authorized accounts.
-
DevOps and Multi-Account Strategies: In environments that leverage multiple AWS accounts for different stages of the software development lifecycle (dev, staging, production) or for isolating different applications, cross-account discovery simplifies the process of moving services between environments and ensuring they can be discovered and accessed by the appropriate deployment pipelines or user groups.
-
Improved Resilience and Disaster Recovery: By enabling services in one account to discover and connect to failover services or read replicas deployed in a separate AWS account (potentially in a different region), organizations can build more robust and resilient architectures.
How it Works:
The implementation of cross-account service discovery in AWS Cloud Map is designed to be secure and straightforward. When registering a service, you can now explicitly grant access permissions to other AWS accounts. This allows principals in those authorized accounts to query AWS Cloud Map and discover the registered services. The underlying mechanism leverages AWS Identity and Access Management (IAM) to ensure that only authorized entities can access service information, maintaining the security posture of your cloud environment.
Getting Started:
To leverage this new functionality, you will need to configure IAM policies in both the service-owning account and the account that needs to discover the service. This typically involves granting the necessary permissions for services to query AWS Cloud Map and for principals to perform cloudmap:DiscoverInstances actions. AWS provides comprehensive documentation and examples to guide you through the setup process.
Conclusion:
AWS Cloud Map’s new support for cross-account service discovery represents a significant advancement in AWS’s commitment to simplifying cloud operations and enabling sophisticated architectures. By breaking down account silos for service discovery, AWS Cloud Map empowers organizations to build more agile, collaborative, and resilient applications in the cloud. We encourage our customers to explore this new feature and experience the benefits of streamlined, secure, and comprehensive service discovery across their AWS accounts.
