Bonus Review Mode Set 5 Question 2 – Answer incorrectly framed

[SalientListener]

Please note – the correct answer is wrongly saying “Create an AWS Lambda function that calls the RunTask API operation when the container finishes transcoding the video.” – this should be “Create an AWS Lambda function that calls the RunTask API operation when the S3 bucket receives the file upload event notification”. The RunTask API will CALL the Fargate container to start the transcoding – and not the other way around.

A global streaming company uses a Java application on an Amazon EC2 instance to transcode videos for its platform. The application starts processing the videos to different resolutions every time they are uploaded to an Amazon S3 bucket. It takes approximately 40 minutes to transcode each video. The application keeps track of the transcoded videos and will only process each file once.

Upon reviewing Amazon CloudWatch metrics, a solutions architect noted that the EC2 instance is idle for 35% of the time on average. The solutions architect is required to make the workload highly available and scalable, and reduce management overhead.

What should the architect recommend for the MOST cost-effective solution?

(ANSWER) a container image out of the video transcoding application. Deploy and run the container image on Amazon Elastic Container Service (Amazon ECS) on AWS Fargate. Create an AWS Lambda function that calls the Fargate RunTask API operation when the container finishes transcoding the video. Use an S3 event notification to invoke the Lambda function.
