API Gateway

The problem

In a microservice architecture, letting each client call every service directly multiplies the entry points to secure and makes the system hard to evolve.

The solution

A single gateway that centralises routing to the various microservices, applies security in one place and hides the internal topology from clients.

My role

Personal project: full design and implementation of the gateway.

Results

• Single entry point for all microservices
• Security rules defined once, applied everywhere

Tech stack
