A solutions architect is designing a system that processes uploaded images. When an image is uploaded to S3, it needs to be resized, watermarked, and analyzed for inappropriate content. These three tasks can be done in parallel. Which architecture provides the MOST scalable and loosely coupled solution?

Configure S3 to trigger a single Lambda function that performs all three tasks sequentially.

Configure S3 to send an event to an Amazon SQS queue. Have three EC2 instances poll the queue.

Configure S3 to send an event to an Amazon SNS topic. Subscribe three separate Amazon SQS queues to the topic, and have separate Lambda functions process each queue.

Use AWS Step Functions to orchestrate the three tasks sequentially.
