Short answer: uthorization using an API Gateway? Rate Limiting: Use the API Gateway to limit the number of requests a client can make in a given period to prevent abuse and overload. uthorization using an API Gateway?

Rate Limiting: Use the API Gateway to limit the number of requests a client can make in a given period to prevent abuse and overload. This can be done using libraries or built-in functionality in the gateway (e.g., NGINX, Kong). Limit each client to 100 requests per minute. uthentication: The API Gateway can… integrate with external identity providers (e.g., OAuth 2.0, JWT) to authenticate requests. It verifies the client's identity before forwarding requests to the microservices. Example code If a request includes a valid JWT token, the gateway passes it long; otherwise, it responds with an authentication error. uthorization: The API Gateway can handle Role-Based Access Control (RBAC) by verifying user roles from the authentication token (JWT) and enforcing access restrictions based on the user's privileges. Example: Only admins can access /admin endpoints, while regular users can access /user endpoints. uthorization using an API Gateway?

Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
