Google Web Server (GWS) is proprietary web server software that Google uses for its web infrastructure. GWS is used exclusively inside Google's ecosystem for website hosting.
In 2008 GWS team was led by Bharat Mediratta.[https://web.archive.org/web/20080416222246/http://www.ginside.com/2008/1489/interview-bharat-mediratta/ Interview with Bharat Mediratta About the Google Web Server]. Jonathan Dingman, Ginside.com, 03/24/2008 GWS is sometimes described as one of the most guarded components of Google's infrastructure.[http://www.dein.fr/static/files/FOSS-Google-Chrome.pdf Google Chrome: free software as a launching platform] {{Webarchive|url=https://web.archive.org/web/20190724054203/http://www.dein.fr/static/files/FOSS-Google-Chrome.pdf |date=2019-07-24 }}, Charles-Axel Dein 2009
In 2010 GWS was reported as serving 13% of all web sites in the world.{{Cite web|url=https://www.theregister.co.uk/2010/01/29/google_web_server/|title = Google mystery server runs 13% of active websites| website=The Register }}
In May, 2015, GWS was ranked as the fourth most popular web server on the internet after Apache, nginx and Microsoft IIS, powering an estimated 7.95% of active websites.{{cite web|title=May 2015 Web Server Survey|date=19 May 2015 |url=https://news.netcraft.com/archives/2015/05/19/may-2015-web-server-survey.html|access-date=2018-12-05}} Web page requests on most Google pages provide "gws" (without a version number) in the HTTP header as an indication of the web server software being used.
Information regarding GWS is scarce. In a blog post from Google's Chicago office in 2011, Google provided some details on GWS:
{{quotation | "The Google Web Server (GWS) team builds and improves the proprietary web-serving infrastructure that powers Google web search and many other Google search properties. GWS is involved in almost every user-visible change to the google.com site, meaning that there's frequently something to write home about. We're always looking for gung-ho engineers, ideally with a background in systems and experience working with very large C++ codebases."{{cite web|title=Google Chicago Job Openings|url=https://www.google.com/intl/en/jobs/uslocations/chicago/index.html|archive-url=https://web.archive.org/web/20120415021232/http://www.google.com/intl/en/jobs/uslocations/chicago/index.html|url-status=dead|archive-date=2012-04-15|access-date=2018-12-05}} |author= |title= |source= }}
