Creating an Amazon Neptune database using AWS CDK v2

Provisioning a graph database cluster in AWS using TypeScript.

The AWS Cloud Development Kit (AWS CDK) allows developers to define cloud infrastructure in code and provision it through AWS CloudFormation. Version 2 of the AWS CDK is the next major version of the AWS CDK that, while being functionally equivalent to AWS CDK v1, aims to further simplify Infrastructure as Code (IAC) by following a single-package approach and improving the overall development experience.

Amazon Neptune is AWS's graph database offering that lets you provision managed graph database clusters and query them using Gremlin and SPARQL. Like other AWS resources, Amazon Neptune clusters can be created and managed using the AWS CDK.

Below is an example CDK stack that provisions an Amazon Neptune cluster:

import { Stack, StackProps } from "aws-cdk-lib";
import * as ec2 from "aws-cdk-lib/aws-ec2";
import * as neptune from "@aws-cdk/aws-neptune-alpha";
import { Construct } from "constructs";

export class MyStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);

    const vpc = new ec2.Vpc(this, "my-vpc");

    const cluster = new neptune.DatabaseCluster(this, "my-database-cluster", {
      vpc,
      instanceType: neptune.InstanceType.T3_MEDIUM,
    });
  }
}
