API Gateway

An HTTP reverse proxy with support for:

• basic request routing
• custom request authentication
• rate limiting
• CORS configuration

Purpose

This little proxy is designed to sit between the public L7 HTTP/HTTPS load balancer and the services in a private network. It is successfully used in production at BlueHealth, where it routes incoming traffic from GCP Cloud Load Balancer to respective Kube service withing GKE cluster. We chose to build it to accomodate our custom authenticate strategy and provide a minimum set of features an API gateway should have.

Builing
