This AWS Solutions Construct implements Amazon DynamoDB table with stream, AWS Lambda function and Amazon Elasticsearch Service with the least privileged permissions.

Here is a minimal deployable pattern definition:

const { DynamoDBStreamToLambdaToElasticSearchAndKibana, DynamoDBStreamToLambdaToElasticSearchAndKibanaProps } = require('@aws-solutions-constructs/aws-dynamodb-stream-lambda-elasticsearch-kibana');

const props: DynamoDBStreamToLambdaToElasticSearchAndKibanaProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler'
    },
    domainName: 'test-domain'
};

new DynamoDBStreamToLambdaToElasticSearchAndKibana(stack, 'test-dynamodb-stream-lambda-elasticsearch-kibana', props);

Initializer

new DynamoDBStreamToLambdaToElasticSearchAndKibana(scope: Construct, id: string, props: DynamoDBStreamToLambdaToElasticSearchAndKibanaProps);

Parameters

• scope Construct
• id string
• props DynamoDBStreamToLambdaToElasticSearchAndKibanaProps

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

Amazon DynamoDB Table

• Set the billing mode for DynamoDB Table to On-Demand (Pay per request)
• Enable server-side encryption for DynamoDB Table using AWS managed KMS Key
• Creates a partition key called 'id' for DynamoDB Table
• Retain the Table when deleting the CloudFormation stack

AWS Lambda Function

• Configure least privilege access IAM role for Lambda function
• Enable reusing connections with Keep-Alive for NodeJs Lambda function

Amazon Cognito

• Set password policy for User Pools
• Enforce the advanced security mode for User Pools

Amazon Elasticsearch Service

• Deploy best practices CloudWatch Alarms for the Elasticsearch Domain
• Secure the Kibana dashboard access with Cognito User Pools
• Enable server-side encryption for Elasticsearch Domain using AWS managed KMS Key
• Enable node-to-node encryption for Elasticsearch Domain
• Configure the cluster for the Amazon ES domain
