Considerations for CloudFront
- Very large audience
- Viewers all over the world (e.g. for tourism)
- High bandwidth. For a high bandwidth CloudFront it is cheaper than just the player.
Considerations for a subdomain
- Easier to remember
- Easier to update the player without disruption.
Publish a second player and switch the subdomain when done.
- The underlaying technology can be changed without any changes to the viewer.
