AWS CloudFormation

• Model and set up AWS resources via:– Templates that describe all the AWS resources that you want (like

Amazon EC2 instances or Amazon RDS DB instances), and provisions and configures those resources for you.

– Stacks that cluster resources so they don’t need to be individually created and configured or figure out what's dependent on what

• Provides– Simplified Infrastructure Management– Quickly Replicate Your Infrastructure– Easily Control and Track Changes to Your Infrastructure

Problems with Client-Side Ad Insertion

• User experience is bad• Loading times, to the ad stream, then back to the regular content• Inconsistency in the codecs, bit rates, and aspect ratios

• Ad signalling is interpreted by the player• Specific developments to support multiple platforms and players• No elegant solution to handle ad insertion in live channels and events• Third party plugins can kill the business model

We also use AWS innovation for VOD content

• Achieved through adjacent pre-fetching

• And other video packet delivery optimization

• Large scale deployment of high quality video via the cloud is now possible and is happening

• Balance is required to create and maintain customer satisfaction and trust

• Cloud workflows can be engineered to be as resilient and reliable as on-premise workflows
