How to architect a video site, from a performance point of view

I want to build a high traffic video site, which has many videos and visitors, using ASP.NET. But I have no experience of high traffic sites and video 开发者_开发问答sites.

Anyone can give me some stuff to read or some keywords for me to google? In the performance point of view.

Many thanks :)

UPDATE: I said our site is similar to Youtube, but that just meant that the site structure would be similar to Youtube. We won't have that high traffic. So I delete that sentence, sorry for confusing you :)

Depends a bit on what you mean with performance and where you see potential issues with it. There is the perfomance of the website in general where a video hosting site is not much different then any other site. There is the frontend performance, etc.

Where a video hosting site is different to most other sites is the ammount of data to be transfered and the performance for video rendering. Means probably the first wall to hit is the bandwith of ones webserver (if you would be starting with one standard machine) or the CPU going mad.

-> First step would be to seperate website from video delivery and encoding to be able to scale.

Now I don't know about ASP.NET but with Drupal there are many people who have done similar sites to youtube [1] and there are many contrib modules [2] to support also above mentioned tasks like Media Mover [3]. Might give you a starting point.
