What are API Gateways for GPT-4?

API gateways act as centralized entry points that manage, secure, and route requests between clients and backend services in an application or microservices architecture. They handle essential functions such as authentication, rate limiting, load balancing, caching, and request transformation to optimize performance and security. By consolidating these controls, API gateways simplify communication, reduce latency, and ensure consistent governance across multiple APIs. They also provide analytics and monitoring to help developers track usage and detect issues in real time. Ultimately, API gateways improve scalability, reliability, and security for modern, distributed applications.
