If you live in Japan, you know that Rakuten is an equivalent to Yahoo or eBay. For everyone else Wikipedia tells us that "Rakuten is among the Top 10 largest Internet companies in the world (along with Amazon.com, InterActive Corporation (IAC), Expedia, etc.)" and provides "Japan's largest online retail marketplace".
While GlassFish production usage at Rakuten is still pretty recent, it does use clustering and the engineering leader who answered the questionnaire (whose name we couldn't mention unfortunately) calls it a "nice middle ground" (compared to other solutions such as Tomcat or Weblogic). She also suggests a few enhancements which you can find, along with other interesting tidbits, in the detailed questionnaire (original Japanese version here).
Rakuten's online shopping business (one of 8 major lines of business for the company), Rakuten Ichiba, is the largest online shopping mall in Japan, and allows customers to shop more than 18 million products from over 25,000 merchants. The number of Rakuten members is now above 42 Million (which is one third the country total population). Looks like a nice growth perspective for GlassFish to me!
