Rakuten is one of the largest e-commerce platforms in Japan and perhaps the world. They chose GlassFish to form a core of their extensive (24 X 7) platform (they also use Oracle Coherence). Makito Hashiyama, the lead for the Rakuten marketplace platform shared their adoption story at the JavaOne 2013 Sunday GlassFish community event - check out the video below:
Here is the slide deck for his talk:
Makito detailed how GlassFish enabled Rakuten to handle the peak load of one of the biggest online sales events in Japan. By tuning GlassFish worker threads on a (42 X 3) instance cluster (perhaps one of the largest production GlassFish deployments in the world) Rakuten was able to process 12,000 transactions per minute despite having a high latency external system dependency. The stress tests actually proved the GlassFish cluster could handle up to 20,000 transactions per minute.
Makito mentioned that one of the key reasons Rakuten adopted GlassFish for their platform was because of early support for Java EE standards such as JAX-WS. He also mentioned that beyond simply using GlassFish Rakuten regularly contributes patches into the GlassFish code base.
