Source: AWS What's New

Share

Amazon Bedrock AgentCore Memory now enables cross-account access, allowing you to build multi-account architectures where memory resources and consuming agents span multiple AWS accounts. You can grant principals in one account permission to call memory data plane APIs against resources in another account using resource-based policies, and configure memory delivery destinations (Amazon S3, Amazon SNS, Amazon Kinesis Data Streams) that reside in a separate account. Cross-account access is configured by attaching a resource-based policy to your memory resource. Once configured, principals in the
