As you may know, Red Hat Enterprise Linux is among the most popular Linux system for servers and the business environment. It is a proprietary software, the users having to pay for both the license and technical support.
Recently, the RHEL team has announced that all the developers enrolled in the company’s Developer Program can download the system for free, right from the official website. The Red Hat JBoss Middleware portfolio of enterprise-class application and integration middleware software has been also made available for free, as well. The free RHEL software is offered under a non-production self-supported developer subscription, being usable for local app development only, not for production purposes.
While RHEL is not free, Red Hat is the biggest open-source supporter, being involved in a lot of important projects, including Fedora, CentOS or GNOME.
