We have been using multiple metrics, such as downloads and registrations, to measure GlassFish adoption, all of which you can check out at The Aquarium
. For example, GlassFish has been the most downloaded application server for quite some time, and is a leading indicator of what can happen further down the road.
Down that road, another metric is to measure the adoption of an open source project by other open source projects. Because "open source" projects have source code publicly available, it is possible to automate the gathering of data/metadata for open source projects, which offers non-subjective evidence of adoption. Ohloh
by SourceForge) has been doing just that, by crawling 38,000 projects across 3,500 source forges. With the support of Ohloh, we have been able to measure the adoption of GlassFish within open source communities.
The results are in with this report
, and GlassFish adoption has shown continued within open source communities. In fact, the first graph shows that GlassFish is now the most targeted application server among open source projects, with over 50% of those projects supporting GlassFish. The second graph (below) shows that new projects target GlassFish a stunning 73% of the time, far surpassing any other application server. Note that in both cases, projects can support more than one application server, hence the results total more than 100%.
The results of GlassFish adoption is apparent when you consider the growth in monetization of GlassFish. While Sun does not break out GlassFish Enterprise Server in our earnings reports, GlassFish is contributing to the growth of software infrastructure at Sun, and is a leading indicator that shows that the future opportunity looks bright for GlassFish Enterprise Server.
