Red Hat has sought to reduce complexity in RHEL 8, which comes with ten guaranteed years of enterprise support. Their model involves repositories for the base operating system as well as application streams for flexible lifecycle options, which offer multiple versions of databases, languages, various compilers, and other tools to help facilitate the use of RHEL for business models. Build-in defaults in RHEL 8 include tuned profiles for database options (ready-to-go options out of the box) and ansible system roles to provide a common configuration interface (ensuring standardization and reliability)The RHEL 8 YUM package manager is now based on the Dandified Yum (DNF) technology, which supports modular content, better performance, and a stable API for integration with tooling. User feedback indicated that “yum is a lot faster than it used to be, and all the commands work well.”
