Q: In how many continents does Amazon CloudFront have edge locations?

The main difference between Route 53 and Cloudfront is that Route 53 is a DNS service while Cloudfront is a CDN service that serves static and dynamic content. Cloudfront can be used with Route 53 Geolocation Routing. Although, the content delivery based on the location is enabled before-hand in cloudfront , so the geolocation policy is not of much help.

Amazon CloudFront retrieves files twice as fast as Amazon S3

To use a single CloudFront web distribution to serve content from multiple origins by configuring multiple cache behaviors, follow these steps:

• From CloudFront console, go to web distribution.
• Select the Origins tab and create 2 origins, one for S3 bucket and another for the load balancer.
• Select the Behaviors tab and create a behavior.
• Specify a path pattern so that all the static content requests are routed to S3 Bucket.
• Edit the path pattern behavior in Default (*), setting its Origin as the load balancer.

Amazon CloudFront supports using several AWS resources as origins, including Amazon S3 buckets, MediaStore containers, MediaPackage channels, and custom origins such as your own HTTP servers

Geo-Targeting in Amazon CloudFront identifies the user's country and sends this information to your server. You can then tailor content based on the user's location and store it at nearby locations for faster access.
