A media company is building a new content delivery platform. They need to store terabytes of video content that will be frequently accessed by users worldwide. The primary requirements are low latency for global viewers, high availability, and cost-effectiveness for frequently accessed objects. Which storage solution combination should they choose?
- AAmazon S3 Standard for storage and Amazon CloudFront for content delivery.
- BAmazon EBS volumes attached to EC2 instances for storage and a custom CDN solution.
- CAmazon EFS for storage and AWS Global Accelerator for content delivery.
- DAmazon S3 Glacier Deep Archive for storage and Amazon CloudFront for content delivery.
Show answer & explanationAnswer & explanation
Correct answer: A. Amazon S3 Standard for storage and Amazon CloudFront for content delivery.
Amazon S3 Standard offers high durability and availability for frequently accessed data, while Amazon CloudFront is a global CDN that caches content at edge locations, providing low latency access to users worldwide.
Why the other options are wrong
- B. EBS volumes are block storage for single EC2 instances, not a scalable or cost-effective solution for global content delivery, and a custom CDN adds complexity.
- C. Amazon EFS is a network file system for EC2 instances, not typically used as a global content repository for public access directly. AWS Global Accelerator is for improving application performance, not a CDN for static content.
- D. S3 Glacier Deep Archive is for archival data with infrequent access and high retrieval times, not suitable for frequently accessed video.
S3 Standard with CloudFront
Combining Amazon S3 Standard for object storage with Amazon CloudFront for content delivery creates a highly available, scalable, and low-latency solution for serving frequently accessed static content globally.
- S3 Standard: high availability, durability, frequent access.
- CloudFront: global CDN, caches content at edge locations.
- Reduces latency for users worldwide.
- Cost-effective for global content delivery.
Memory trick: S3 holds the treasures, CloudFront delivers them fast around the world.
