Putting it all together

?

• Multiple delivery protocols for different platforms and devices

• Adobe RTMP

• HTTP streaming for iOS

• Microsoft Silverlight

• Options for live and on-demand video

• Full control over origin for live streaming

• Reliability backed by CloudFront Service Level Agreement

Reliable delivery to wide range of clients

“With CloudFront’s strong

performance, ease of use and

flexibility, our team can use the API or

the Console to quickly make changes

to our CDN configuration and see the

updates within minutes.  And with the

low cost of delivering dynamic content

using CloudFront, we expect to see

significant cost savings as well.”

What customers are saying

What customers are saying

AWS’ reliable infrastructure makes it

easier to focus on other tasks

“As with all the other AWS services we

leverage, using Amazon CloudFront is

so simple and reliable that the team

doesn’t have to think about it. It all just

works, freeing us to focus on building

cool applications.”

What customers are saying

NASA Tells the World About Mars

with AWS

Shortly before the landing, NASA/JPL

provisioned stacks of AWS

infrastructure, each capable of

handling 25 Gbps of traffic. As traffic

volumes returned to normal hours after

the landing, NASA/JPL used AWS

CloudFormation to de-provision

resources using a single command.

Best Practices

OFFLOAD static content• reduce your compute demand and costs• improve end-user experience• increase reliability and durability
