Build a robust API gateway that serves as the single entry point for all your backend services. Implement intelligent request routing to direct traffic to the appropriate microservices, enable sophisticated load balancing to distribute requests efficiently across your infrastructure, and centralize authentication and authorization to secure all API endpoints. Protect your services with advanced rate limiting that prevents abuse and overload, manage multiple API versions seamlessly to support legacy clients while rolling out new features, and transform requests and responses on the fly to adapt to different client requirements. Boost performance with an integrated caching layer that stores frequently accessed data, monitor API health and usage through real-time metrics and comprehensive logs, and handle SSL termination at the gateway level for simplified security. Perfect for managing microservices architectures, implementing API rate limiting and quotas, integrating legacy systems without backend changes, adding a security layer with centralized authentication, tracking usage for API monetization, and serving multi-platform clients including web, mobile, and IoT devices.
