The Power of API Gateway in Building a Secure and Scalable E-Commerce Application

TLDRDiscover the key role of API gateway in creating a secure, scalable, and efficient e-commerce application. Learn how it separates cross-cutting concerns, routes requests, improves performance, and enhances security.

Key insights

🔐API gateway separates cross-cutting concerns, such as authentication and authorization, from business logic, making the e-commerce application more modular and manageable.

🚀By consolidating multiple requests into a single response, API gateway improves performance and reduces network calls, resulting in faster rendering of web pages.

🔄API gateway can route requests to different microservices based on URL paths, enabling efficient load balancing, canary releases, and A/B testing.

🔋With response caching, API gateway can store and serve frequently accessed responses, reducing network latency and improving overall responsiveness.

🔒API gateway can handle protocol translations, allowing legacy services to seamlessly communicate with newer protocols like WebSocket and HTTP/2.

Q&A
