AWS Cloud Practitioner CLF-C02 Practice Question

AWS Lambda is the best choice for the given scenario as it allows running code without provisioning or managing servers and automatically scales with the number of incoming requests. This suits occasional, stateless, and independent data processing jobs and is cost-efficient as you pay only for the compute time consumed. EC2 instances would require manual scaling and can incur costs while idle. Fargate is designed for containers and would not be the most cost-effective for occasional jobs. Elastic Beanstalk provides an additional layer of management for applications, which is unnecessary for stateless, short-lived data processing tasks.
