Elephants in tunnels: how Hyperdrive connects to databases inside your VPC networks

Cloudflare has announced that its Hyperdrive service can now send database traffic from Workers over Cloudflare Tunnels. This feature aims to make accessing centralized databases faster and more consistent for users, while also keeping connections hot. The integration of Hyperdrive with Tunnels is designed to provide a secure connection between private networks and Cloudflare without exposing sensitive data on the public internet. This solution leverages Rust traits to handle Postgres message traffic as just bytes, allowing flexibility in implementing logic for new features.
