Educational Video Platform

A startup launches a platform where users upload educational videos. A single uploaded video may need to be converted into 1080p, 720p, 480p and mobile-optimised formats. Encoding is CPU-intensive and can take several minutes, and thousands of videos may be uploaded at the same time. The company does not want to maintain dedicated encoding servers. A failed encoding job should be retried automatically, and one failed video must not block the others. Once processed, users should be able to stream the videos globally.
