Should I use a S3 bucket or a download distribution?
Through testing, we found that a CloudFront distribution each time performance better than linking via a bucket. In theory, if your audience is primarily located in your own country, a s3 bucket should be sufficient, bu in practice it turns out differently..
There is an additional cost involved using CloudFront, but this is very reasonable.
With S3Media Stream Enterprise, you are obliged to use a web distributions for links, HLS and 360 VR video.
