Easily distribute content to end users

with low latency, high data transfer

speeds, and no commitments.

Static, Dynamic & Streaming

AWS CloudFront – Dynamic Contents

Dynamic content is the interactive or personalized portion of a website, created on-the-fly for each end user

• News• Weather• Sports• Social media• Advertising• Travel


AWS CloudFront – Dynamic Contents

• Simple DIY configuration with web console • No consultants to hire, No proprietary languages to learn

Simple to Use

• Connections to AWS regions closely monitored• Standard AWS resources (like CloudFormation)• Designed to work with origins in Amazon EC2

AWS Integratio

n

• No additional charges or set up fees• Pay only for requests and data transferLow Cost

• Multiple Cache Behaviors, Minimum Expiration Period• Multiple Origin Servers Origin Connection Protocol, Query String

Parameters• Viewer Connection Protocol ∙ Cookie Support

Features


AWS CloudFront – Streaming Services

High internet bandwidth platform EC2 scalability & pricing model• Use it only when you need it• No need to over-commit HW or infrastructure: Grow as needed

ECO System & license flexibility• Streaming solution partners• DRM solution partners• BYOL and Pay-as-you-go

If requirement fits…• No commitment CDN service as CloudFront• Use S3 as unlimited contents storage ( 99.999999999% durability)• Easy and fully managed CloudFront + S3 VoD + Elastic Transcoder

platform


AWS CloudFront – Media Security Requirements

AWS alignment to MPAA Security Best Practices reviewed October 2012Based on AWS Shared Responsibility ModelAWS Services In Scope• Elastic Compute Cloud (EC2), Virtual Private Cloud (VPC), Simple Storage

Service (S3), Elastic Block Storage (EBS), Relational Database Service (RDS), DynamoDB, VM Import, Elastic Load Balancing (ELB), Identity and Access Management (IAM), CloudFront, Glacier, AWS Import/Export, Direct Connect, Route 53, Elastic Transcoder, and the supporting data centers

Content Types In Scope • RAW master, high/low-resolution, watermarked/spoiled, full/partial feature content,

stills, clips, frames, shots, sequences, scripts, storyboards as well as production and post-production deliverable formats in pre-and post-theatrical release windows

AWS Elastic Transcoder

• Different bit rate• Different frame rate• Max width / height• Different sizing policy• Different Aspect ratio

Multiple types of transcoding at once& only pay for the minutes of the content


AWS Elastic Transcoder Service - Details

Reduce cost• No more CapEx (server / storage / network and DC requirement)• No more OpEx (operations / maintenance and management)• Unlimited storage with S3 with 99.999999999% of durability @ no extra cost (better

durability than “most” traditional DR solution) + Unlimited archiving with Glacier• Only pay for “how many minutes” you transcoded

Enhance security• Data at rest for S3 storage• IAM to manage the resource access management• Visual watermarking for transcoded media content• Security eco systems with AWS partners

Configurable transcoding presets• Container: MP4 / TS / WebM• Video: H.264 / vp8• Audio: AAS / vorbis• Presets : up to 4 images (jpg / png)


Media Use Case


Pay as you go


NASA’s JPL used AWS to stream the images and video associated with Curiosity’s landing targeting hundreds of thousands viewer.

They developed set of EC2 Nginx cache Tier with CloudFormation to handle 25Gbps streaming each. They provisioned capacity with monitoring the actual usage.

Mars Science Laboratory


Corporate website, 40 producer websites, streaming for iPhone and iPad applicationsUse Amazon EC2, Amazon S3, Amazon RDS, and stream 1.5 PB/m on Amazon CloudFrontBusiness Benefits• Launched and scaled multiple media services quickly• Improved server set-up time from months to 15 minutes• Improved reliability to 99.99%

PBS Online and Mobile Media on AWS

“I can’t imagine having been able to do very many of the things that we’ve done, in the timeframe that we’ve done them, without the benefit of a platform like this.”

– Jon Brendsel, VP, Products


More than 25 Million Streaming Members

50 Billion Events Per Day

30 Million plays every day

2 billion hours of video in 3 months

4 million ratings per day

3 million searches

Device location , time , day, week etc.

Social data


Netflix Runs Nearly 100% of its Online Video Service on AWS, Achieves Near Zero DowntimeGlobal Use of Amazon EC2, Amazon S3, Amazon SQS, Amazon EMRBusiness Benefits• Application achieves near zero downtime• Sales to handle Netflix’s rapid online growth, 37x in 2010, over 20B requests per month by Jan 2011

Netflix on AWS

“AWS is the market leader and has been able to create a continuous and virtuous cycle.”

– Kevin McEntee, VP Content Engineering, Netflix


AWS Strengths for Streaming Services

High internet bandwidth platform EC2 scalability & pricing model• Use it only when you need it• No need to over-commit HW or infrastructure: Grow as needed

ECO System & license flexibility• Streaming solution partners• DRM solution partners• BYOL and Pay-as-you-go

If requirement fits…• No commitment CDN service as CloudFront• Use S3 as unlimited contents storage ( 99.999999999% durability)• Easy and fully managed CloudFront + S3 VoD + Elastic Transcoder platform

1. Capture live event via cameras

2. Video editing before streaming

3. Feed edited live event to encoder at the site

4. Encode the live event and transmit to streaming server on AWS cloud

5. Streaming server forwards contents to the edge cache server

6. Streaming server saves the contents to the file

7. End-user watches the live events delivered from edge servers

9. Saved contents get stored in S3 for durability and transcoding if necessary

8. End-devices pushes logs to S3 for data analysis

1. Content owner copies the media content to S3 via StorageGateway or Data Import/Export service provided by AWS2. Media contents are transcoded using Elastic Transcoder if necessary

3. CloudFront is configured for the distribution of digital contents

4. When end-users sends request for VoD streaming, it is served by closest edge cache server

5. PC / Smart devices or OTT sends out logs to S3 for data analysis
