When to use Amazon Cloudfront or S3

Question

Are there use cases that lend themselves better to Amazon cloudfront over s3 or the other way around? I'm trying to understand the difference between the 2 through examples.

Answer 1

• Amazon S3 is simple storage service for internet with large capacity and provides secure,durable and highly scalable object storage.
• Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations
• When an object is requsted by end user using the domain name, they are automatically routed to the nearest edge location for high performance delivery of your content.
• The data served by CloudFront may or may not come from S3. Since it is more optimized for delivery speed, the bandwidth costs a little more.
• If user base is localized, then it won't make difference working with S3 or CloudFront . but  if user base is spread globally and speed is important, CloudFront may be a better option.
• Both S3 and CloudFront allow domain aliases, however CloudFront allows multiple aliases so that d1.mystatics.com, d2.mystatics.com and d3.mystatics.com could all point to the same location increasing the capacity for parallel downloads
