How does an API Gateway assist in implementing authentication and authorization for APIs?
- It centralizes authentication and authorization logic, acting as a security guard for APIs
- It encrypts the data exchanged between APIs
- It only authenticates users and does not handle authorization
- It provides a platform for developing APIs but does not handle authentication and authorization
An API Gateway assists by centralizing authentication and authorization logic, serving as a security layer for APIs, ensuring secure access and controlled permissions.
What advanced feature of API Gateways can be used for aggregating responses from multiple services?
- Data Merging
- Response Composition
- Result Concatenation
- Service Aggregation
API Gateways can use Response Composition as an advanced feature to aggregate responses from multiple services.
