Facebook’s scaling challenge

Facebook’s scaling challenge


Facebook serves 570 billion page views per month (according to Google Ad Planner).


There are more photos on Facebook than all other photo sites combined (including sites like Flickr).

More than 3 billion photos are uploaded every month.

Facebook’s systems serve 1.2 million photos per second. This doesn’t include the images served by Facebook’s CDN.

More than 25 billion pieces of content (status updates, comments, etc) are shared every month.

Facebook has more than 30,000 servers (and this number is from last year!)

Antonio Riva and Ruichi Yamaguchi

Antonio Riva and Ruichi Yamaguchi


Antonio Riva

Capitano (It. captain) Antonio Riva, (8 April 1896 Shanghai – 17 August 1951 Beijing) was an Italian pilot and a World War I flying ace, credited with seven confirmed and seven unconfirmed aerial victories...

... Antonio was executed in Beijing, China, by a firing squad in 1951, along with a Japanese citizen, Ruichi Yamaguchi. They were convicted of being involved in a plot to assassinate Mao Zedong and other high-ranking Communist officials.[3]. The plot allegedly involved attacking Mao and other officials atop Tiananmen Gate with a mortar on the 1st of October 1950, during National Day celebrations...

wikipedia

According to Time magazine’s coverage of the affair, Radio Peking said that
“the streets they passed through [en route to execution] were thronged with people who expressed their feelings .. . with shouts of ‘Down with imperialism! Suppress counterrevolutionaries! Long live Chairman Mao!’”
