Meaning
An API gateway is a server that acts as an API front‑end, receiving API requests, enforcing throttling and security policies, passing requests to the back‑end services, and returning the response.
Primary Function
Acts as a single entry point for all client requests, handling request routing, composition, protocol translation, authentication, authorization, rate limiting, caching, and monitoring.
Communicative Purpose
To refer to the architectural component that serves as the entry point for API traffic in a microservices or cloud‑native architecture.
Pattern
client request → API gateway → authentication/authorization → routing → backend service
Core Structure
The API gateway pattern consists of a server that sits between clients and backend services, handling cross‑cutting concerns such as authentication, SSL termination, request routing, load balancing, and response aggregation.

Erros comuns
Confusing an API gateway with a reverse proxy or service mesh; assuming it handles business logic.

Interferências
Do not confuse API gateway with service mesh; the former manages north‑south traffic, the latter manages east‑west traffic.

Nuance
An API gateway can provide additional capabilities such as request/response transformation, caching, logging, and analytics beyond simple routing.
Efeito pragmático
Invokes the concept of a centralized entry point for managing API traffic and enforcing policies such as security and throttling.
Dica de memória
Think of an API gateway as the front door to your microservices.
Nota
API gateways can also perform request/response transformation, logging, and metrics collection, extending beyond simple routing.
