Securing Quick access from corporate networks with AWS PrivateLink

This guide details how to use AWS PrivateLink VPC endpoints to keep all Amazon Quick traffic to on‑premises data sources off the public internet, leveraging an existing AWS Direct Connect or Site‑to‑Site VPN link. By routing Quick’s data‑fetching connections through PrivateLink, enterprises gain a reduced attack surface, consistent low‑latency connectivity, and a clear audit trail for compliance regimes such as HIPAA, FedRAMP, and PCI‑DSS. The architecture also layers security groups and endpoint policies for defense‑in‑depth, ensuring that Quick’s console, API, and data‑fetching paths remain private.

⚡ Key Takeaways

• VPC endpoints powered by AWS PrivateLink are used to connect Amazon Quick to on‑premises data sources without traversing the public internet.
• Data‑fetching traffic (e.g., Quick Sight queries to PostgreSQL, MySQL, SQL Server, Oracle) travels over VPC connections that rely on ENIs placed in the customer VPC.
• Security groups and VPC endpoint policies provide additional defense‑in‑depth for the private connections.
• The solution assumes an existing AWS Direct Connect or Site‑to‑Site VPN link between the on‑premises environment and the VPC.
• No public internet exposure means lower latency and a clearer audit trail for regulatory compliance.

Engineers can now integrate Amazon Quick with sensitive enterprise data while meeting strict compliance requirements, without redesigning network topology or exposing data to the internet.

✅ Practical Steps

1. Ensure an AWS Direct Connect or Site‑to‑Site VPN connection is established between your on‑premises network and the target VPC.
2. Create VPC endpoints using AWS PrivateLink for the Amazon Quick services that need to reach private resources, and attach appropriate security groups.
3. Define VPC endpoint policies that restrict access to only the required on‑premises data sources and action connectors.
