AWS CDK construct for deploying production-ready Bedrock AI agents with Lambda, DynamoDB, and OpenSearch.

Installation

pip install substrai-cdk-bedrock-agent

Usage

from aws_cdk import App, Stack
from substrai_cdk_bedrock_agent import BedrockAgentConstruct, BedrockAgentProps

app = App()
stack = Stack(app, "AgentStack")

agent = BedrockAgentConstruct(stack, "MyAgent", props=BedrockAgentProps(
    agent_name="my-assistant",
    model_id="anthropic.claude-3-5-sonnet-20241022-v2:0",
    lambda_code_path="./agent_lambda",
    lambda_memory_mb=1024,
    session_ttl_days=14,
))

# Access created resources
print(agent.agent_function.function_arn)
print(agent.session_table.table_name)

What Gets Deployed

• Lambda Function — Agent logic with configurable runtime, memory, and timeout
• DynamoDB Table — Session state with TTL auto-expiry and point-in-time recovery
• IAM Role — Least-privilege permissions for Bedrock and DynamoDB
• CloudWatch Log Group — 2-week retention with structured logging
• CloudWatch Alarms — Error rate and P99 latency monitoring
• X-Ray Tracing — Active tracing enabled by default
