This serverless architecture enables real-time AI chat using AWS services. A WebSocket Amazon API Gateway maintains persistent connections between clients and a Node.js AWS Lambda function. The AWS Lambda function handles user connections/disconnections, stores connection IDs in Amazon DynamoDB, and processes messages through an Amazon Bedrock LLM. The system includes error handling, automatic scaling, and pay-per-use pricing. The AWS SAM template provisions all necessary resources and IAM permissions, outputting a WebSocket URL for client connections.
