A media company is launching a new video streaming platform and anticipates millions of concurrent users globally. They need to ensure that video content is delivered with the lowest possible latency and highest availability to users located across different continents. Which AWS service should be used to achieve this goal?
- AAmazon S3
- BAmazon Route 53
- CAmazon EC2
- DAmazon CloudFront
Show answer & explanationAnswer & explanation
Correct answer: D. Amazon CloudFront
Amazon CloudFront is a global content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. It caches content at edge locations close to users, reducing the distance data travels and improving performance for streaming platforms.
Why the other options are wrong
- A. Amazon S3 is object storage, suitable for storing video files, but it does not inherently optimize global delivery for low latency.
- B. Amazon Route 53 is a DNS web service for routing traffic, but it doesn't cache or deliver content itself; it directs users to resources.
- C. Amazon EC2 provides virtual servers, which can host video servers, but it doesn't automatically distribute content globally or optimize for lowest latency delivery to millions of users.
Amazon CloudFront
A fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds.
- Uses a global network of edge locations.
- Caches content closer to users.
- Integrates with other AWS services like S3 and EC2.
Memory trick: CloudFront: Front and center of global delivery.
