First and foremost: about 10-20 Exabytes worth of storage space, or roughly 4 Petabytes per day.
That’s 4,000,000 Gigabytes of new video per day.
And of course you’d need an efficient way of loading all that video data and streaming it to the end users, so they don’t experience major interruptions, even when hundreds of thousands of people are all watching the same video at the same time. Youtube does this with caching servers/proxies, and highly optimized data delivery algorithms.
Once you have all that infrastructure, just make sure it’s free and ad-free for all the watchers and uploaders. It’s not like you need to pay for all those servers and storage… right?
