Amazon API Gateway lets you integrate with other AWS directly without needing a Lambda function. This "functionless" approach allows you to eliminate Lambda functions from your architecture and all that entails. The potential cold start overhead, the cost associated with Lambda invocations and any scaling limit (such as Lambda's burst capacity limit) related to Lambda functions.

This is a useful pattern for simple CRUD endpoints that do only one thing. For example, to fetch an order from a DynamoDB table and return it to the caller.

But everything is a trade-off. Using this approach also means you miss out on many useful patterns that can be implemented in your Lambda function. Such as the ability to add contextual logging around errors, or using fallbacks, and many distributed tracing tools won't work without a Lambda function to collect the necessary telemetry data.
