Multi-agent orchestrator on AWS Bedrock coordinates supervisor and worker agents across two availability zones using Bedrock AgentCore, LangGraph on Fargate, Step Functions, and ECS. User requests flow through API Gateway and Bedrock Guardrails into the orchestrator layer, which routes tasks via EventBridge and SQS to Lambda action groups and EC2 worker agents. Context, traces, and vector embeddings persist in DynamoDB, OpenSearch Serverless, and RDS across private subnets, with CloudWatch and X-Ray monitoring the entire workflow. This architecture demonstrates high-availability multi-agent coordination with least-privilege IAM roles, VPC isolation, and cross-AZ redundancy.
