What role does the API Gateway play in a microservices architecture?
A) It acts as an entry point for all client requests, routing them to the appropriate services
B) It manages database transactions across services
C) It serves as a data storage solution for microservices
D) It handles logging and monitoring of microservices
Answer:
A) It acts as an entry point for all client requests, routing them to the appropriate services
Explanation:
An API Gateway is a critical component in a microservices architecture, acting as a single entry point for all client requests. The API Gateway handles routing, composition, and protocol translation, directing requests to the appropriate backend microservices.
In addition to routing, the API Gateway can perform various cross-cutting concerns, such as authentication, authorization, logging, rate limiting, and load balancing. By centralizing these responsibilities, the API Gateway simplifies the client’s interaction with the microservices, providing a unified interface while hiding the complexity of the backend system.
