Answer: Create an AWS Lambda function. Ensure that the function is warm by scheduling an Amazon EventBridge rule to invoke the Lambda function every 5 minutes by using mock events.
An AWS Lambda function integrates seamlessly with Amazon API Gateway and introduces the lowest operational overhead compared to managing clusters on Amazon ECS or EKS. Although maintaining warmth through EventBridge might seem redundant for "occasional" invocations, it is functionally sound within the given choices and requires far less management overhead compared to setting up fully provisioned infrastructure or clusters.

Question 41
A company has a frontend ReactJS website that uses Amazon API Gateway to invoke REST APIs. The APIs perform the functionality of the website. A data engineer needs to write a Python script that can be occasionally invoked through API Gateway. The code must return results to API Gateway. Which solution will meet these requirements with the LEAST operational overhead?
A
Deploy a custom Python script on an Amazon Elastic Container Service (Amazon ECS) cluster.
B
Create an AWS Lambda Python function with provisioned concurrency.
C
Deploy a custom Python script that can integrate with API Gateway on Amazon Elastic Kubernetes Service (Amazon EKS).
D
Create an AWS Lambda function. Ensure that the function is warm by scheduling an Amazon EventBridge rule to invoke the Lambda function every 5 minutes by using mock events.
