Thanks to Sun Microsystems, Java has an open source history dating back over ten years.

In 2006, the OpenJDK project was announced.  It took a while to remove some lingering proprietary components but, with build 53 of OpenJDK 7, we finally had a fully open source version of the JDK.  This also became the source code for the reference implementation of the Java SE standard as of Java SE 7.

On the enterprise Java side of things, the GlassFish open-source application server project was launched back in 2005.  In 2006, this also became the reference implementation for the Java EE specification (starting with Java EE 5).

Giving people access to the source code of projects like this is an excellent way to promote adoption of these technologies.  Deploying them into an enterprise environment, however, with defined service level agreements requires more than just source code.  Most organisations, whilst happy to develop and maintain their application code, do not want to take on this kind of task for the infrastructure their applications run on.

Things like the Java runtime and application server consist of millions of lines of code with complicated build processes.  Just setting up a build environment for these can be a significant challenge and require skilled engineers to keep up with changes.

Then there’s the whole aspect of how to deal with updates necessary to address security issues, improvements and bug fixes.

This is where Payara and Azul can help.

Both Payara and Azul provide services essential to deploying mission-critical applications on the enterprise Java platform:

If your business uses applications that run on a Java application server there’s no better, or more cost-effective solution than using Payara and Azul to support your infrastructure - find out more.
