SAP-C02 Question 146
Select 2A media company wants to design a new video streaming platform on AWS. The platform must automatically scale to handle millions of users during peak times, provide low latency streaming globally, and optimize costs. Which combination of AWS services should the company use to meet these requirements?
- A
Amazon S3 for storing video files and Amazon CloudFront for global content delivery
- B
Amazon EC2 Auto Scaling groups for hosting the video streaming application and Amazon Route 53 for domain name management
- C
AWS Elemental MediaPackage for video preparation and packaging and Amazon CloudFront for global video delivery
- D
Amazon RDS for storing video files and Amazon ElastiCache for caching video metadata
- E
AWS Lambda and Amazon API Gateway for handling video streaming requests
Show answer and explanation
Correct answers: A, C
Explanation
To design a scalable and low-latency video streaming platform, the combination of Amazon S3 and CloudFront is ideal for storing and delivering content globally. AWS Elemental MediaPackage further enhances the solution by preparing video content for adaptive streaming formats, ensuring seamless playback for millions of users. Other options, such as EC2 Auto Scaling and Lambda, do not directly cater to the specific requirements of video storage or delivery.
- A. Correct.
Correct: Amazon S3 provides durable and highly available storage for video files, while Amazon CloudFront ensures low-latency, high-speed global content delivery.
- B. Incorrect.
Incorrect: While EC2 Auto Scaling can scale the application layer, it does not directly address video storage or global content delivery. Route 53 is used for DNS management, not for video streaming.
- C. Correct.
Correct: AWS Elemental MediaPackage prepares and optimizes video content for streaming, while Amazon CloudFront delivers it globally with low latency.
- D. Incorrect.
Incorrect: Amazon RDS is not suitable for storing large video files, and ElastiCache is not designed for video metadata caching in this context.
- E. Incorrect.
Incorrect: AWS Lambda and API Gateway can handle lightweight requests but are not suitable for video streaming workloads due to their stateless and resource-limited nature.
