Demystifying API Gateways

🔑API gateways sit between client devices and internal microservices, extracting common logic and providing security.

🔒API gateways handle authorization and authentication, determining if a user is allowed to make a request.

🔄API gateways can transform and massage request data to meet the specific requirements of each internal microservice.

✔️API gateways perform validation on incoming requests to ensure they are correct.

⚖️API gateways can handle load balancing to distribute requests across multiple instances of a microservice.

Where does the API gateway sit in the architecture?

—The API gateway sits between client devices and internal microservices, acting as a middle layer.

What are the benefits of using an API gateway?

—API gateways provide benefits like authorization, request transformation, validation, and load balancing.

Do API gateways handle authentication?
