An API gateway ni hatua moja ya kuingia ambayo inakaa mbele ya huduma za backend — inashughulikia mambo ya ubiquituus kama routing, uthibitisho, rate limiting, na zaidi. Ni muhimu sana katika usanifu wa microservices kwa kusambaza kazi za kawaida.
Kile API gateway kinachofanya
The API GATEWAY is a single entry point in front of backend services:
Client → API GATEWAY → ┬→ Service A
├→ Service B
└→ Service C
→ handles cross-cutting concerns in ONE place (so services don't each implement them)
→ routes requests to the right service; abstracts the backend from clients
