Google Office In Zurich, Switzerland

Google entered the enterprise market in February 2002 with the launch of its Google Search Appliance, targeted toward providing search technology for larger organizations. Google launched the Mini three years later, which was targeted at smaller organizations. Late in 2006, Google began to sell Custom Search Business Edition, providing customers with an advertising-free window into Google.com's index. The service was renamed Google Site Search in 2008.
Another one of Google's enterprise products is Google Apps Premier Edition. The service, and its accompanying Google Apps Education Edition and Standard Edition, allow companies, schools, and other organizations to bring Google's online applications, such as Gmail and Google Documents, into their own domain. The Premier Edition specifically includes extras over the Standard Edition such as more disk space, API access, and premium support, and it costs $50 per user per year. A large implementation of Google Apps with 38,000 users is at Lakehead University in Thunder Bay, Ontario, Canada. In the same year Google Apps was launched, Google acquired Postini and proceeded to integrate the company's security technologies into Google Apps under the name Google Postini Services.
