A company wants to migrate a critical application to AWS. The application has a short runtime. The application is invoked by changes in data or by shifts in system state. The company needs a compute solution that maximizes operational efficiency and minimizes the cost of running the application.
Which AWS solution should the company use to meet these requirements?
To meet the company's requirements of migrating a critical application with a short runtime that is invoked by changes in data or system state, and to maximize operational efficiency while minimizing costs, AWS Lambda is the most suitable solution. AWS Lambda is a serverless compute service which means it automatically scales with the demand and allows users to pay only for the compute time consumed, rather than provisioning and paying for infrastructure upfront. This makes it highly efficient and cost-effective for applications with short runtimes that are triggered by specific events.
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.
There are many clues in the question that points to AWS Lambda definition.
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.
A. Amazon EC2 On-Demand Instances
i'm not convinced as to how a serveless service such as lambda can minimize cost. 'on demand ' seems more appropriate to me.
A. On Demand
B. Lambda
B correct
AWS Lambda
Answer is B
AWS Lambda it is

AWS Lambda is best for event-driven apps.
