API gateways process all API requests made between applications and deliver the requested data into one place. Because they sit at the center of all API calls made between applications, they are used to facilitate traffic management, security, authentication, and access to app data. Using an API gateway, teams can configure key policies such as rate limiting, caching, service discovery, load balancing, and usage analysis with comprehensive reports.
API Gateways are crucial components in modern application development due to their role in serving as a bridge between internal APIs and external clients. An API gateway solution integrates with various back-end services to enable management control and enhance security by enforcing authentication and authorization. This protects your valuable data and services, resulting in a seamless user experience – the end user can view all requested API data in a single place, such as an admin console showcasing data from multiple apps. Some businesses may also charge for API usage – for this use case, API gateways can monitor usage and protect API traffic to ensure good service for customers.
