Google data centers are located in North and South America, Asia, and Europe. There is no official data on the number of servers in Google data centers; however, research and advisory firm Gartner estimated in a July 2016 report that Google at the time had 2.5 million servers. Traditionally, Google relied on parallel computing on commodity hardware like mainstream x86 computers (similar to home PCs) to keep costs per query low. In 2005, it started developing its own designs, which were only revealed in 2009.
As per its 2017 Annual report, Google generates most of its revenues from advertising. This includes sales of apps, purchases made in-app, digital content products on google and YouTube, android and licensing and service fees, including fees received for Google Cloud offerings. 46% of this was from clicks (cost per clicks), amounting to US$109,652 million in 2017. This includes three principal methods, namely AdMob, AdSense (such as AdSense for Content, AdSense for Search, etc.) and DoubleClick AdExchange.
More InfoBy late 2006, Google established a new headquarters for its AdWords division in Ann Arbor, Michigan. In November 2006, Google opened offices on Carnegie Mellon's campus in Pittsburgh, focusing on shopping-related advertisement coding and smartphone applications and programs. Other office locations in the U.S. include Atlanta, Georgia; Austin, Texas; Boulder, Colorado; Cambridge, Massachusetts; San Francisco, California; Seattle, Washington; Kirkland, Washington; Birmingham, Michigan; Reston, Virginia, and Washington, D.C.
More InfoIn September 2016, Google began its Google Station initiative, a project for public Wi-Fi at railway stations in India. Caesar Sengupta, VP for Google's next billion users, told The Verge that 15,000 people get online for the first time thanks to Google Station and that 3.5 million people use the service every month. The expansion meant that Google was looking for partners around the world to further develop the initiative, which promised "high-quality, secure, easily accessible Wi-Fi". By December, Google Station had been deployed at 100 railway stations, and in February, Google announced its intention to expand beyond railway stations, with a plan to bring citywide Wi-Fi to Pune.
More InfoOn August 8, 2017, Google fired employee James Damore after he distributed a memo throughout the company which argued that bias and "Google's ideological echo chamber" clouded their thinking about diversity and inclusion, and that it is also biological factors, not discrimination alone, that cause the average woman to be less interested than men in technical positions. Google CEO Sundar Pichai accused Damore in violating company policy by "advancing harmful gender stereotypes in our workplace", and he was fired on the same day. New York Times columnist David Brooks argued Pichai had mishandled the case, and called for his resignation.
More InfoIn 2005, The Washington Post reported on a 700 percent increase in third-quarter profit for Google, largely thanks to large companies shifting their advertising strategies from newspapers, magazines, and television to the Internet. In May 2011, the number of monthly unique visitors to Google surpassed one billion for the first time. By 2011, Google was handling approximately 3 billion searches per day. To handle this workload, Google built 11 data centers around the world with some several thousand servers in each. These data centers allowed Google to handle the ever changing workload more efficiently.
