AWS SAA-C03 · Question 26 · Domain 2.3: Decoupling
A media company has an application that processes video files. Users upload videos to an Amazon S3 bucket. The processing takes several minutes per video and is handled by a fleet of Amazon EC2 instances. The company wants to decouple the upload process from the video processing to ensure the system remains responsive even during traffic spikes. <br/><br/>What is the MOST resilient way to architect this?
Answer options:
Configure S3 Event Notifications to invoke an AWS Lambda function that processes the video.
Configure S3 Event Notifications to send a message to an Amazon SQS queue. Configure an Auto Scaling group of EC2 instances to poll the queue and process the videos.
Configure S3 Event Notifications to send a message to an Amazon SNS topic. Have the EC2 instances subscribe to the topic.
Have the EC2 instances continuously poll the S3 bucket for new objects using the ListObjects API.
