RHEL 6 was first released in November 2010 and is no longer the leading edge of Red Hat’s platform efforts. In June 2014, RHEL 7 debuted, providing new file system and Docker container support. Just because Red Hat is working on RHEL 7 doesn’t mean it’s leaving its RHEL 6 users behind. Red Hat has a 10-year life cycle process for its operating system platform, which includes multiple phases of support.
