What is API Gateway?
A server that acts as a single entry point for all API requests, routing them to the appropriate backend service.
Why It Matters
An API gateway simplifies client interactions, handles authentication, and provides rate limiting in one place.
Real-World Example
All mobile app requests go through one API gateway that routes them to the correct microservice.
“Understanding terms like API Gateway matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
