2. AGENDA
• Why do you need a CDN?
• Amazon Cloudfront – Introduction
• Architecting with Amazon Cloudfront
• Amazon Cloudfront – Features
• Amazon Cloudfront – Case Studies
• Amazon Cloudfront – Demo
• Amazon Cloudfront – Benefits

3. WHY DO YOU NEED A CDN?

4. Rising consumption of content for
longer time across an ever-growing
range of devices
Expectation for excellent performance
– no buffering, loading or delays
Explosion of online video consumption
Limit storage and delivery costs
Increased global broadband penetration
requires serving a widely dispersed
audience
Industry trends & common challenges for content providers

8. CloudFront in a Nutshell
• Low latency: Improves content load times
• High bandwidth: Enables high bit rate HD video and other bandwidth-heavy applications
• Redundant: Eliminates single points of failure
• Scalable: Ensure great experience as number of end users grows
• Global: Worldwide network provides great experience regardless of geography
• Cost-effective: Pay as you go model provides flexibility for your business
