Language Package

This AWS Solutions Constructs pattern 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 = { 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);


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


Pattern Construct Props

Name Type Description
existingLambdaObj? lambda.Function An optional, existing Lambda function to be used instead of the default function. If an existing function is provided, the lambdaFunctionProps property will be ignored.
lambdaFunctionProps? lambda.FunctionProps Optional user-provided properties to override the default properties for the Lambda function. Ignored if an existingLambdaObj is provided.
dynamoTableProps? dynamodb.TableProps Optional user provided props to override the default props for DynamoDB Table
existingTableObj? dynamodb.Table Existing instance of DynamoDB Table. If this is set, then the dynamoTableProps is ignored.
dynamoEventSourceProps? aws-lambda-event-sources.DynamoEventSourceProps Optional user provided props to override the default props for DynamoDB Event Source
esDomainProps? elasticsearch.CfnDomainProps Optional user provided props to override the default props for the Amazon Elasticsearch Service
domainName string Domain name for the Cognito and the Amazon Elasticsearch Service

Default settings

Out-of-the-box implementation of this pattern without any overrides 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
