Caucho Technology's Resin Web Server powers more than 4.7 million websites worldwide, according to the latest release of Netcraft's Web Server Survey. In the report, Netcraft noted that the Resin application server experienced strong growth over the past 12 months; seeing an almost tenfold growth from 480k hostnames in February 2011 to 4.7 million (0.77 percent of the market) in February 2012.

"Resin's incredible growth is driven by fast performance speed, built-in server monitoring capabilities and extreme reliability," said Caucho Technology.

Founded in 1998, Caucho Technology released version 1.0 of resin in 1999. Companies including the Toronto Stock Exchange, Salesforce and CNET have deployed on Resin, the Java Application Server designed for high-traffic sites that require speed and scalability.

In 2008 the company released Resin 4.0, the first Java EE Web Profile certified Java application server, and since initial release Resin 4 has been optimized to work in cloud computing environments like Amazon EC2.

According to Caucho Technology, the Resin Web Server is a fast, stand-alone Web server that includes reverse proxy, load balancing, URL rewrites, FastCGI, and HTTP proxy cache. Resin's core networking code is written in highly optimized C and users can extend Resin Web Server by using the Java Servlet API.

Resin is available in two versions: Resin Open Source and Resin Professional. As noted on the company's website, Resin Open Source (GPL) is designed for low-traffic development, hobby and personal sites. It offers a number of features including auto restart, PHP on the JVM and active community support.

Resin Professional is cloud-optimized and designed for business and government where high performance, reliability, security and DevOps is required. Resin Professional features Health System, Java EE 6 web profile and priority technical support provided by Caucho engineers. Resin's Health System provides server and JVM monitoring and full server recoverability.

"Resin's growth is due to our 14 year track record of performance and reliability," said Scott Ferguson, Chief Architect of Caucho Technology. Ferguson added, "The additional health monitoring and third-generation clustering technology that we have added to Resin 4 position it for sites migrating to the cloud."
