Selected Answer: B

From: https://aws.amazon.com/lambda/ 1. Run code without provisioning or managing infrastructure. Simply write and upload code as a .zip file or container image. 2. Automatically respond to code execution requests at any scale, from a dozen events per day to hundreds of thousands per second. 3. Save costs by paying only for the compute time you use—by per-millisecond—instead of provisioning infrastructure upfront for peak capacity.

Selected Answer: B

Based on the requirements of the application having a short runtime, being invoked by changes in data or system state, and the need to maximize operational efficiency and minimize costs, AWS Lambda is the most suitable solution. AWS Lambda is a serverless compute service that allows you to run code without provisioning or managing servers. It automatically scales and manages the infrastructure required to run the code in response to incoming requests or events. Since the application has a short runtime and is invoked by events, AWS Lambda's event-driven architecture is well-suited for this scenario.
