Overview

This AWS Solutions Construct implements (1) an AWS Lambda function that is configured to send messages to a queue; (2) an Amazon SQS queue; and (3) an AWS Lambda function configured to consume messages from the queue.

Here is a minimal deployable pattern definition:

Typescript

import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { LambdaToSqsToLambda, LambdaToSqsToLambdaProps } from "@aws-solutions-constructs/aws-lambda-sqs-lambda";
import * as lambda from 'aws-cdk-lib/aws-lambda';

new LambdaToSqsToLambda(this, 'LambdaToSqsToLambdaPattern', {
  producerLambdaFunctionProps: {
      runtime: lambda.Runtime.NODEJS_16_X,
      handler: 'index.handler',
      code: lambda.Code.fromAsset(`producer-lambda`)
  },
  consumerLambdaFunctionProps: {
    runtime: lambda.Runtime.NODEJS_16_X,
    handler: 'index.handler',
    code: lambda.Code.fromAsset(`consumer-lambda`)
  }
});

Python

from aws_solutions_constructs.aws_lambda_sqs_lambda import LambdaToSqsToLambda
from aws_cdk import (
    aws_lambda as _lambda,
    Stack
)
from constructs import Construct

LambdaToSqsToLambda(
    self, 'LambdaToSqsToLambdaPattern',
    producer_lambda_function_props=_lambda.FunctionProps(
        code=_lambda.Code.from_asset('producer_lambda'),
        runtime=_lambda.Runtime.PYTHON_3_9,
        handler='index.handler'
    ),
    consumer_lambda_function_props=_lambda.FunctionProps(
        code=_lambda.Code.from_asset('consumer_lambda'),
        runtime=_lambda.Runtime.PYTHON_3_9,
        handler='index.handler'
    )
)

                .build())
        .build());

Default Settings

Out-of-the-box implementation of this Construct (without any overridden properties) will adhere to the following defaults:

AWS Lambda Functions

• Configure limited privilege access IAM role for Lambda functions.

• Enable reusing connections with Keep-Alive for NodeJs Lambda functions.

• Enable X-Ray Tracing

• Set Environment Variables

  • AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)

Amazon SQS Queue

• Deploy a dead letter queue for the primary queue.
• Enable server-side encryption for the primary queue using an AWS Managed KMS Key.
• Enforce encryption of data in transit
