AWS Privatelink for MongoDB Atlas PoC

Introduction

This Proof of Concept (PoC) demonstrates the integration of MongoDB Atlas with AWS PrivateLink. This setup provides a secure, private connection to MongoDB Atlas from an AWS VPC, leveraging AWS PrivateLink technology.

Why AWS PrivateLink for MongoDB Atlas?

AWS PrivateLink offers a private connectivity solution between AWS services and on-premises networks. It is particularly beneficial in scenarios where data security and network performance are paramount. Unlike traditional methods, such as public endpoints or VPC peering, PrivateLink provides a more secure and scalable approach. It does so by ensuring that the traffic between AWS and MongoDB Atlas does not traverse the public internet, thus reducing exposure to potential threats.

When to Use AWS PrivateLink over VPC Peering?

AWS PrivateLink is recommended over VPC peering in scenarios where:

• Enhanced security and privacy are critical.
• There is a need to connect multiple VPCs to MongoDB Atlas without complex routing or overlapping IP issues.
• The architecture demands consistent low-latency connectivity.
• The organization prefers a streamlined network management process with less overhead.
