Which of the following would be a good solution for content distribution?

Content and Media Server is the latest requirement that you need to meet for a client.

The client has been very specific about his requirements such as low latency, high availability, durability, and access control. Potentially there will be millions of views on this server and because of “spiky” usage patterns, operations teams will need to provision static hardware, network, and management resources to support the maximum expected need. The Customer base will be initially low but is expected to grow and become more geographically distributed.

Which of the following would be a good solution for content distribution?
A . Amazon S3 as both the origin server and for caching
B . AWS Storage Gateway as the origin server and Amazon EC2 for caching
C . AWS CloudFront as both the origin server and for caching
D . Amazon S3 as the origin server and Amazon CloudFront for caching

Answer: D

Explanation:

As your customer base grows and becomes more geographically distributed, using a high- performance edge cache like Amazon CloudFront can provide substantial improvements in latency, fault tolerance, and cost.

By using Amazon S3 as the origin server for the Amazon CloudFront distribution, you gain the advantages of fast in-network data transfer rates, simple publishing/caching workflow, and a unified security framework.

Amazon S3 and Amazon CloudFront can be configured by a web service, the AWS Management Console, or a host of third-party management tools.
