Do you count using a cloud provider as hosting your own?

The most basic pipeline for doing it is going to look something like this:

1) Upload the original video to a storage bucket.

2) Have some compute service transcode the video file to create other renditions.

3) Store those renditions in a different storage bucket.

4) Put a CDN service in front of the transcoded renditions.

Get ready for a nice bandwidth bill if anyone actually watches your videos!
