The API Gateway Has Grown Up
When API gateways first entered the enterprise architecture conversation, the value proposition was straightforward: put a reverse proxy in front of your APIs, enforce authentication, and add basic rate limiting. Problem solved.

The modern API gateway is an integration hub in its own right, and understanding its full capabilities is essential to building a resilient, scalable API strategy.
