A company wants to create a mobile app that allows users to stream slow-motion video clips on their mobile devices. Currently, the app captures video clips and uploads the video clips in raw format into an Amazon S3 bucket. The app retrieves these video clips directly from the S3 bucket. However, the videos are large in their raw format.

Users are experiencing issues with buffering and playback on mobile devices. The company wants to implement solutions to maximize the performance and scalability of the app while minimizing operational overhead.

Which combination of solutions will meet these requirements? (Select TWO.)

Answers
E.
Deploy an Auto Scaling group of Amazon EC2 Instances to convert the video files to more appropriate formats.
Suggested answer: A, C

Explanation:

Understanding the Requirement: The mobile app captures and uploads raw video clips to S3, but users experience buffering and playback issues due to the large size of these videos.

Analysis of Options:

Amazon CloudFront: A content delivery network (CDN) that can cache and deliver content globally with low latency. It helps reduce buffering by delivering content from edge locations closer to the users.

AWS DataSync: Primarily used for data transfer and replication across AWS Regions, which does not directly address the video size and buffering issue.

Amazon Elastic Transcoder: A media transcoding service that can convert raw video files into formats and resolutions more suitable for streaming, reducing the size and improving playback performance.

EC2 Instances in Local Zones: While this could provide content delivery and caching, it involves more operational overhead compared to using CloudFront.

EC2 Instances for Transcoding: Involves setting up and maintaining infrastructure, leading to higher operational overhead compared to using Elastic Transcoder.

Best Combination of Solutions:

Deploy Amazon CloudFront: This optimizes the performance by caching content at edge locations, reducing latency and buffering for users.

Use Amazon Elastic Transcoder: This reduces the file size and converts videos into formats better suited for streaming on mobile devices.
