With cross-account access, principals in separate AWS accounts can interact with AgentCore Memory APIs on resources owned elsewhere, supporting distributed and multi-tenant deployments. Resource-based policies control permissions, enabling coordinated memory usage and data operations across organizational boundaries.
Cross-account delivery destinations allow memory event data and payloads to stream to S3, SNS, or Kinesis Data Streams in different accounts. This flexibility fosters complex architectures but requires careful permission management. The feature is broadly available in all supported AWS regions, expanding the scope of memory resource utilization.
