How can I integrate an API Gateway with a serverless architecture?

Integrating an API Gateway with a serverless architecture typically involves using services like AWS Lambda or Azure Functions. You set up the API Gateway to route requests to your serverless functions.

What are the benefits of using an API Gateway in this setup?

The benefits include simplified request routing, built-in security features, and the ability to manage traffic effectively. It also helps in monitoring and logging API calls.

Can you give me an example of a use case?

Sure! A common use case is a mobile application that needs to fetch data from a database. The API Gateway can handle requests from the app and route them to a Lambda function that queries the database.

What are some common challenges I might face?

Common challenges include managing cold starts in serverless functions, handling API rate limits, and ensuring proper authentication and authorization.
