It’s all Java. You can read about it at [Automation World](http://www.automationworld.com/opc-ua-stack-written-java-write-once-run-anywhere).

From this [web page](http://www.inductiveautomation.com/scada-software/opc-ua-server) on the IA site:

Can I run it on Windows and Linux?  
Yes. Being written in 100% pure Java means that Ignition OPC-UA runs just as well on Linux as it does on Windows. In fact, any operating system that supports Java 6 will run Ignition OPC-UA.

Whose OPC-UA Stack are you using?  
Our own. We were the first company to independently develop an OPC-UA stack from scratch and successfully test it at a major interoperability workshop. We know OPC-UA inside and out, and are very excited about being on the forefront of the future of industrial communication.
