When citizens upload photos to a code-enforcement bucket, the city wants automatic thumbnail creation. Which service best fits that event-driven pattern?
Select an answer to reveal the explanation.
Short Explanation
Upload happens, thumbnail pops out—that is classic event-driven Lambda. An always-on idle EC2 box works but wastes money; Direct Connect and Route 53 move networks and DNS, not pixels.
Full Explanation
AWS Lambda runs code in response to events such as object creation in Amazon S3, which fits automatic thumbnail generation without provisioning servers. This serverless, event-driven model is ideal for intermittent processing tied to uploads. Always-on EC2 can perform similar work but lacks the same pay-per-use fit for sporadic events. Networking and DNS services are unrelated to image transformation logic.
