Question
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.

Which AWS solution should the company use to meet these requirements?a)Amazon EC2 Reserved Instancesb)Amazon EC2 Spot Instancesc)AWS Lambdad)Amazon EC2 On-Demand Instances
Solution
The company should use c) AWS Lambda. AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. This makes it a perfect fit for applications that are invoked by changes in data or shifts in system state and have a short runtime. It maximizes operational efficiency as you don't have to provision, scale, or manage any servers. It also minimizes cost as you only pay for the compute time you consume - there is no charge when your code is not running.
