Delivery: There & back again...

Many Moving Parts

• File Storage– Pushing files around infrastructure (secs-hours)

• Transcoding (Autobot)– multiple formats, bottlenecks; (mins-hours)

• iTunes U– webservice (secs-minutes)– can go offline or fail to respond

• YouTube– sFTP for file transfer (secs-hours)– transcoding (mins-hours)– webservice (GDATA) to confirm complete (secs)
