Explanation

The most cost-effective and scalable solution for generating thumbnails when photos are uploaded to an S3 bucket is to useS3 event notificationsto trigger anAWS Lambda function. This approach avoids the need for a long-running EC2 instance or EMR cluster, making it highly cost- effective because Lambda only charges for the time it takes to process each event. S3 Event Notifications: Automatically triggers the Lambda function when a new photo is uploaded to the S3 AWS Lambda: A serverless compute service that scales automatically and only charges for execution time, which makes it the most economical choice when dealing with periodic events like The Lambda function can generate the thumbnail and upload it to a second S3 bucket, fulfilling the requirement efficiently. Option A and Option B (EMR or EC2 with scheduled scripts)**: These are less cost-effective as they involve continuously running infrastructure, which incurs unnecessary costs. Option D (S3 Storage Lens): S3 Storage Lens is a tool for storage analytics and is not designed for event-based photo processing.
