The correct answer is C. Store a copy of every video in every required bitrate in an Amazon S3 bucket. Use a single. The most cost-effective solution for serving video content with different bitrates is to store multiple versions of each video inAmazon S3. S3 provides scalable and cost-effective storage for largemedia files. Serving the videos from a single Amazon EC2 instance ensures low-laten
Question
An online education platform experiences lag and buffering during peak usage hours, when thousands of students access video lessons concurrently. A solutions architect needs to improve the performance of the education platform. The platform needs to handle unpredictable traffic surges without losing responsiveness. The platform must provide smooth video playback performance at all times. The platform must create multiple copies of each video lesson and store the copies in various bitrates to serve users who have different internet speeds. The smallest video size is 7 GB. Which solution will meet these requirements MOST cost-effectively?
Options
- AUse Amazon ElastiCache to cache videos in all the required bitrates. Use AWS Lambda functions
- BCreate an Auto Scaling group that includes Amazon EC2 instances that are sized to meet peak
- CStore a copy of every video in every required bitrate in an Amazon S3 bucket. Use a single
- DUse Amazon Kinesis Video Streams to store and serve the videos. Use AWS Lambda functions

Explanation
The most cost-effective solution for serving video content with different bitrates is to store multiple versions of each video inAmazon S3. S3 provides scalable and cost-effective storage for largemedia files. Serving the videos from a single Amazon EC2 instance ensures low-latency delivery, and S3 storage helps minimize costs. Option A (ElastiCache): Caching large video files in memory would be prohibitively expensive and Option B (Auto Scaling group): Using Auto Scaling groups to serve video is less cost-effective compared to leveraging S3 for static storage. Option D (Kinesis Video Streams): Kinesis Video Streams is designed for real-time video streaming and is not suitable for storing and serving pre-recorded videos.
