AWS Lambda Python with Multi-Agent Orchestrator

The Multi-Agent Orchestrator framework can be used inside an AWS Lambda function like any other library. This guide outlines the process of setting up the Multi-Agent Orchestrator System for use with AWS Lambda using Python.

Prerequisites

• AWS account with appropriate permissions
• Python 3.12 or later installed
• Basic familiarity with AWS Lambda and Python

Installation and Setup

1. Create a New Project Directory

   mkdir multi-agent-lambda && cd multi-agent-lambda

2. Create and Activate a Virtual Environment

   python -m venv venv
   source venv/bin/activate  # On Windows, use `venv\Scripts\activate`

3. Install the Multi-Agent Orchestrator Framework

   pip install multi-agent-orchestrator boto3

4. Create Requirements File

   pip freeze > requirements.txt

Lambda Function Structure

Create a new file named lambda_function.py in your project directory. Here’s a high-level overview of what your Lambda function should include:

import json
import asyncio
from typing import Dict, Any
from multi_agent_orchestrator.orchestrator import MultiAgentOrchestrator, OrchestratorConfig
from multi_agent_orchestrator.agents import BedrockLLMAgent, BedrockLLMAgentOptions, AgentResponse

# Initialize orchestrator
orchestrator = MultiAgentOrchestrator(OrchestratorConfig(
    # Configuration options
))

# Add agents
tech_agent = BedrockLLMAgent(BedrockLLMAgentOptions(
    # Agent configuration
))

orchestrator.add_agent(tech_agent)

def serialize_agent_response(response: AgentResponse) -> Dict[str, Any]:
    """Convert AgentResponse into a JSON-serializable dictionary."""
    return {
        "metadata": {
            "agent_id": response.metadata.agent_id,
            "agent_name": response.metadata.agent_name,
            "user_input": response.metadata.user_input,
            "session_id": response.metadata.session_id,
        },
        "output": response.output,
        "streaming": response.streaming,
    }

def lambda_handler(event: Dict[str, Any], context: Any) -> Dict[str, Any]:
    try:
        user_input = event.get('query')
        user_id = event.get('userId')
        session_id = event.get('sessionId')
        response:AgentResponse = asyncio.run(orchestrator.route_request(user_input, user_id, session_id))

        # Serialize the AgentResponse to a JSON-compatible format
        serialized_response = serialize_agent_response(response)

        return {
            "statusCode": 200,
            "body": json.dumps(serialized_response)
        }

    except Exception as e:
        print(f"Error: {str(e)}")
        return {
            "statusCode": 500,
            "body": json.dumps({"error": "Internal Server Error"})
        }

Customize the orchestrator configuration and agent setup according to your specific requirements.

Deployment

Use your preferred method to deploy the Lambda function (e.g., AWS CDK, Terraform, Serverless Framework, AWS SAM, or manual deployment through AWS Console).

IAM Permissions

Ensure your Lambda function’s execution role has permissions to:

• Invoke Amazon Bedrock models
• Write to CloudWatch Logs
