Platform & Infra Services

Design an API Gateway

A single entry point fronting a microservice fleet, handling routing, auth, rate limiting, and observability so individual services don't have to.

Core Architectural Components

Request Routing/Reverse Proxy Layer

Directs each incoming request to the correct backend service.

Authentication/Authorization Middleware

Validates identity and permissions before a request reaches a service.

Rate Limiting & Throttling Module

Protects backend services from being overwhelmed by any single client.

Request/Response Transformation Layer

Adapts payloads between what clients send and what services expect.

Service Discovery Integration

Resolves which backend instances are currently healthy and routable.

Circuit Breaker & Retry Policy Engine

Prevents a failing downstream service from cascading failures upstream.

Centralized Logging & Metrics Middleware

Captures uniform observability data for every request that passes through.

API Versioning & Contract Management

Lets services evolve their API without breaking existing clients.
