A Complete Guide to Production-Grade PrivateLink Setup for Neo4j Enterprise Edition
Blog post from Neo4j
The guide provides a detailed solution for securely exposing a Neo4j Enterprise Edition cluster across Virtual Private Clouds (VPCs) using AWS PrivateLink, without public exposure and with full Transport Layer Security (TLS) and clean private DNS configurations. It addresses challenges commonly faced in enterprise environments, such as the need for secure database connectivity and the risks associated with exposing network connectivity fully. The solution involves using AWS services like Network Load Balancers and PrivateLink to manage cross-VPC connectivity while maintaining cluster communication strictly internal. By configuring Neo4j nodes with specific advertised addresses for Bolt and HTTPS, and implementing security measures like least privilege access and private DNS, the guide ensures high availability, secure client connections, and minimal attack surfaces. This proven approach, based on real-world implementation, offers a scalable, secure, and efficient architecture for enterprises needing cross-region, cross-VPC connectivity for Neo4j.
