The document provides an overview of Amazon CloudFront, a content delivery network (CDN) that enhances user experience through faster content delivery, reduces costs, and improves scalability. It outlines the benefits of using CloudFront, including improved SEO, lower latency, and increased security, while discussing its integration with other AWS services and features such as video streaming and custom origin support. Additionally, the document addresses various challenges in content distribution and presents case studies demonstrating CloudFront's successful implementation in real-world scenarios.

5. How it Works
• A content delivery network (CDN) uses a network of servers in
geographically dispersed locations (edge locations) to cache copies of
content close to end users, lowering latency when they download or stream
the objects.
• When a specific page, file, or program is requested by a user, the server
dynamically selected to deliver the content is based on closest network
proximity or the one with the fewest network hops to the end user.
• Content is replicated across edge locations providing redundancy.
5

6. CDN Benefits
• Improves customer experience with faster page loads - bounce rates
go down and customers stay on your site longer.
• SEO benefits: site speed and load times are important to search
engine ranking.
– A study by Google showed that every ½ second of page load time dropped
customer traffic by 20%. Google factors in page load times in their quality
score.
• Takes load off your web server, brings in scalability.
• Reduces costs.
• Provides protection: redundancy across multiple servers/locations.

12. Streaming
• Refers to delivering audio and video to end users on the
internet without having to download the media file prior
to playback
• Potential benefits for you and your end-users
– Give viewers more control over their viewing experience (seek forward)
– Give you more control over your content (no file remains on the viewer's
computer after watching)
– Reduce your costs as it only delivers portions of a media file that the
viewers actually watch
• Protocols used for streaming include
– Proprietary : Adobe’s Real Time Messaging Protocol (RTMP + tunneled
and encrypted variants)
– HTTP based : Apple’s HTTP Live Streaming (HLS), Adobe’s HTTP
Dynamic Streaming (HDS) and Microsoft’s Smooth Streaming (SS)
12

13. On-Demand Streaming
• 3 Options
– Media files converted to one of the supported format, stored in
Amazon S3 (or a custom origin). You can then use S3 as an origin for
an Amazon CloudFront web distribution.
– Run a third party streaming server (e.g. Wowza Media Server
available on AWS Marketplace) on Amazon EC2 which can convert a
media file to the required HTTP streaming format (HLS, HDS or SS).
This server can then be designated as the origin for an Amazon
CloudFront distribution.
– Stream using RTMP, you can store your media files on Amazon S3
and use it as the origin for an Amazon CloudFront RTMP distribution.
13

14. Live Streaming
• 3 solutions to deliver live events over HTTP
• Each relies on an encoder and a media service or server,
fragments are cached in CloudFront and can be encoded on
different bit rate
• 3 Solutions :
– Wowza Media Server 3.6 : Apple HTTP Live Streaming (HLS), Adobe HTTP
Dynamic Streaming (HDS) and Microsoft Smooth Streaming
– Adobe Media Server 5.0 : Flash Player and Apple iOS devices. Amazon EC2
(running AMS 5.0) must be configured as the origin for a CloudFront web
distribution
– Windows Media Services for live Smooth Streaming : Live media over HTTP to
both Microsoft Silverlight clients and Apple iOS devices
• AWS CloudFormation template are provided to handle
provisioning and sequencing for all the AWS resources of
streaming stacks
