Most of us use Google on a daily basis, but just what goes on behind the scenes that makes searching simple? How much data does Google process per day?
First, let's get a helpful sense of scale:
You may have noticed that the above infographic does put a number on the amount of data processed per day: 20 petabytes or...
1,125,899,906,842,624 bytes.
That statistic is from mid-2007. How has the world changed since then? Though not released every year, on average, the amount of data processed by Google increases 4-9x per year. That means that Google is likely processing on the order of
thousands of petabytes of data per day.
What's unclear is whether or not Google's last-published numbers even include YouTube (since YouTube was not purchased by Google until the very end of 2006). So, just for a few other statistics:
As of March, 2011,
48 hours of video is uploaded to YouTube every minute, up from
24 hours in 2010. In addition, over
1 billion videos are watched per day on YouTube. YouTube is the third-largest website in the world, the largest video sharing website in the world and the second-largest search-engine in the world (after only Google).
Anyways, I like statistics.
