Amazon CloudFront vs. MaxCDN vs. EdgeCast

Amazon CloudFront can be used to deliver your entire website, including dynamic, static, streaming, and interactive content using a global network of edge locations. Requests for your content are automatically routed to the nearest edge location, so content is delivered with the best possible performance.

The MaxCDN Content Delivery Network efficiently delivers your site’s static file through hundreds of servers instead of slogging through a single host. This "smart route" technology distributes your content to your visitors via the city closest to them.

EdgeCast is a content delivery network (CDN) that helps companies accelerate and deliver static and dynamic content to end users around the world. Major customers include Yahoo!, Tumblr, Pinterest, Wordpress, and Imgur. The company has about 4,500 customers (as of June 2012) and carries about 5% of the world’s internet traffic.
