AWS Lambda Timeouts

Optimizing the timeout values for your AWS Lambda functions is crucial to manage costs effectively. Ensure your functions have an appropriate timeout setting to avoid unnecessary expenses.

For instance, when using Lambda with an API Gateway, it's essential to note that API Gateway has a maximum timeout of 29 seconds. If your Lambda function occasionally takes 45 seconds to complete, you incur an additional 15 seconds of wasted computing time. To address this, align your AWS Lambda timeout with the timeout set on your API Gateway, ensuring efficient resource utilization.

In this case, not setting the time out would cost you 50% more.
