I'm sure you have heard of this website, however, few people know the state-of-the-art tech behind it.
If you thought you were simply playing back a video from a single server, let me tell you you were far from the truth;
When you upload your video it will be stored at the data centre nearest you, but when someone wants to play it, the video will be sent to their nearest data centre for quick access. This also means that in the event of a fire or other disaster, the data is sent to another data centre so that it’s always accessible.
This may sound simple, but when every minute there are over 400 hours of videos uploaded to YouTube, this becomes more complicated.
Thank you. Interest,
