In this session, we will build a highly scalable mobile app, website, and serverless mobile backend architecture that demonstrates on-demand video streaming, adaptive multi-bitrate transcoding, and video content ingestion. We use AWS Lambda and Amazon Elastic Transcoder to automatically convert high resolution videos upon upload, Amazon CloudFront to stream video content to devices using network-aware adaptive multi-bitrate protocols (such as HLS), Amazon Cognito to authenticate users, and AWS Mobile Hub and AWS CloudFormation to automate setting up the required resources.
