Overview
This AWS Solutions Construct implements an Amazon SNS connected to an AWS Lambda function.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { SnsToLambda, SnsToLambdaProps } from "@aws-solutions-constructs/aws-sns-lambda";
import * as lambda from 'aws-cdk-lib/aws-lambda';
new SnsToLambda(this, 'test-sns-lambda', {
lambdaFunctionProps: {
runtime: lambda.Runtime.NODEJS_14_X,
handler: 'index.handler',
code: lambda.Code.fromAsset(`lambda`)
}
});
Python
from aws_solutions_constructs.aws_sns_lambda import SnsToLambda
from aws_cdk import (
aws_lambda as _lambda,
Stack
)
from constructs import Construct
SnsToLambda(self, 'test_sns_lambda',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset('lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
)
)
Java
import software.constructs.Construct;
import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awscdk.services.lambda.*;
import software.amazon.awscdk.services.lambda.Runtime;
import software.amazon.awsconstructs.services.snslambda.*;
new SnsToLambda(this, "test-lambda-sqs-stack", new SnsToLambdaProps.Builder()
.lambdaFunctionProps(new FunctionProps.Builder()
.runtime(Runtime.NODEJS_14_X)
.code(Code.fromAsset("lambda"))
.handler("index.handler")
.build())
.build());
Pattern Construct Props
Name | Type | Description |
---|---|---|
existingLambdaObj? | lambda.Function |
Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error. |
lambdaFunctionProps? | lambda.FunctionProps |
User provided props to override the default props for the Lambda function. |
existingTopicObj? | sns.Topic |
Existing instance of SNS Topic object, providing both this and topicProps will cause an error. |
topicProps? | sns.TopicProps |
Optional user provided properties to override the default properties for the SNS topic. |
Pattern Properties
Name | Type | Description |
---|---|---|
lambdaFunction | lambda.Function |
Returns an instance of the Lambda function created by the pattern. |
snsTopic | sns.Topic |
Returns an instance of the SNS topic created by the pattern. |
Default settings
Out of the box implementation of the Construct without any override will set the following defaults:
Amazon SNS Topic
- Configure least privilege access permissions for SNS Topic
- Enable server-side encryption for SNS Topic using AWS managed KMS Key
- Enforce encryption of data in transit
AWS Lambda Function
-
Configure limited privilege access IAM role for Lambda function
-
Enable reusing connections with Keep-Alive for NodeJs Lambda function
-
Enable X-Ray Tracing
-
Set Environment Variables
- AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
