What feature does the API Gateway provide for traffic management?

The API Gateway’s feature for traffic management primarily involves rate limiting. Rate limiting is a technique used to control the number of requests an application receives in a given period. By implementing rate limiting, the API Gateway can help prevent abuse, ensuring that the backend services are not overwhelmed with excessive requests, which could lead to degradation of service or downtime.

With rate limiting, administrators can set thresholds to allow only a certain number of requests from a single client or for specific API endpoints within a specified timeframe. This ensures fair usage among clients, enhances the stability of the applications, and allows for better resource allocation. It can also play a vital role in protecting APIs from Distributed Denial of Service (DDoS) attacks by limiting the number of requests that can be issued by an attacker at any given moment.

The other options do not align with traffic management in the context of an API Gateway. For instance, data encryption and removal, while crucial for data security and privacy, do not directly relate to managing traffic flow. A/B testing tools serve a different purpose related to evaluating user experiences and optimizing applications based on user interactions. Graphic user interfaces, though important for user interaction with the API management functions, do not specifically pertain to traffic management either. Therefore, rate
