Most popular Java application servers: 2017 edition
This is now the 5th year when we publish statistics about the Java landscape. Every year, during springtime, we dig into the data that we have gathered from the JVMs Plumbr Java Agents have monitored. The outcome of this has been published to you to see understand which Java versions are currently the most adopted, which JVM vendor rules the market and what is the distribution of the market for different Java application servers.
Few weeks ago we exposed the data about Java versions and vendors. This week we are exposing the state in the application server market.
The following conclusions are based on 1,633 different deployments that Plumbr monitored for performance during February and March 2017. The data has been gathered from within the JVMs monitored by our Java Agent in SaaS installations of Plumbr.
Which Java application server is the most widely used in 2017?
From the deployments we gathered the data from, we were able to identify the application server and its vendor in just slightly under 60% of the environments. This ratio has been dropping over the years and provides insights on its own. Apparently more and more Java deployments do not really bother with wrapping themselves inside an application server and pick a more lightweight option.
These container vendors distributed as follows:
Tomcat share in the Java application server installation base has grown even more. The 63.9% share of the pie left no question about the winner. In addition to Tomcat, next four vendors having significant deployment base are:
- JBoss/WildFly installations, having 13.8% of the market share
- Jetty, with 9% of the market
- GlassFish, having another 5.6% of the pie
- Oracle WebLogic deployments with 4.5% of the installations
The “Other” category represented less than 3.4% of the installations. This consisted of Resin, Orion, OC4J and IBM WebSphere deployments, all detected in less than five deployments.
Java application servers in use 2013 – 2017
Presenting the same data over the period from 2013 to 2017 where we have analyzed the same data, we see the following:
Just in case you are not into stacked bar charts, here is the raw data in tabular format as well:
There is only one major conclusion that can be drawn from the trends: Tomcat remains the clear #1 preference, extending its footprint slowly but steadily year over year.
Other trends or changes should be interpreted carefully. For example the reason why Jetty dropped to just third of its former glory on 2015 is likely caused by Plumbr transformation from a development tool to a monitoring solution. Instead of the developer-friendly Jetty the production deployments with other Java application servers took its share of the deployments.
