-Prefer to keep it in Azure? The assignment chapter documents an **optional advanced path**: upload the recording to the shared `student-submissions` blob container (teachers get read access, nothing is public) and share a read-only link. The container is shared, so name your file after yourself: `week-11/<your-name>.mp4` (e.g. `week-11/jane-doe.mp4`). See "Optional (advanced): host the recording on Azure Blob Storage" in the Week 11 Assignment chapter.
