This AWS CDK app helps you migrate the simple Neo4j movies graph database to Amazon Neptune in a hands-free, fully-automated way

• Install Node.js and npm
• Install Git
• Install and Configure AWS CLI
• The IAM user configured in the AWS profile must have the privileges to provision the following resources. Please note, while working with AWS acounts, IAM users and policies always follow IAM best practices:
  • Amazon VPC and Subnets
  • Amazon EC2 instance
  • Amazon S3 bucket
  • Amazon S3 Gateway VPC Endpoint
  • An Amazon Neptune cluster
• Install AWS CDK

• Verify the app specific configuration saved in bootstrapper/cdk.json to ensure you have the right values for your environment
  • (Required) replace <your-key-pair-name> with your own EC2 key pair name e.g. my-us-west-2-key-pair
  • (Required) replace <provide-your-ip> with your current IP address e.g. 8.8.8.8/32 Know your IP address

The contents of the file looks like this. Feel free to change the values before running the app

Detailed architecture

The app will ask questions while showing you what it's trying to create. Just respond with a 'y' to let it do its stuff. It will take about 10 minutes to deploy the infrastructure and run the required code to automate the migration.

When you run the app the following are downloaded and installed:

• Neo4j community edition version 4.0.0 using yum install neo4j-4.0.0 -y
• Apache TinkerPop Gremlin Console 3.4.5 from http://apache.mirrors.spacedump.net/tinkerpop/3.4.5/apache-tinkerpop-gremlin-console-3.4.5-bin.zip
• Neo4j movies graph cypher script
• Neo4j APOC plugin version 4.0.0.2 https://github.com/neo4j-contrib/neo4j-apoc-procedures/releases/download/4.0.0.2/apoc-4.0.0.2-all.jar
• Neo4j-to-Neptune tool https://github.com/awslabs/amazon-neptune-tools/tree/master/neo4j-to-neptune
• Customized Docker repositories
  • Neo4j docker: https://hub.docker.com/repository/docker/sanjeets/neo4j-400-export
  • Gremlin console docker: https://hub.docker.com/repository/docker/sanjeets/neptune-gremlinc-345

Please note: the code uses the default AWS CLI profile

To cleanup after you are done
