Red Hat Enterprise Linux (RHEL)



Red Hat Enterprise Linux (RHEL) is a distribution of the Linux operating system developed for the business market. RHEL was formerly known as Red Hat Linux Advanced Server.
RHEL is based on free, open source code. Although Red Hat makes its source code available for download, verbatim copying of the distribution is forbidden. The RHEL operating system (OS) supports diverse workloads in physical, virtualized and cloud environments. RHEL editions are available for servers, mainframe, SAP applications, desktops and Open Stack. The RHEL 6.5 update, based on Linux kernel version 2.6.32-431, provides Precision Time Protocol (PTP) support, centralized certificate administration and security updates, large-scale resource management, broader support for solid-state storage devices and extended subscription management services. RHEL 7, which as this writing is still in beta, will have multiple file systems, supporting EXT4, XFS and btrfs in addition to EXT2 and EXT. The interface will also change, with Gnome 2 classic mode as the default.

Future  roadmap of Red Hat Linux :



Today, Red Hat’s no longer the radical upstart open source entrant. We’re an established software company that sells known-safe software. Our customers trust the dependencies, libraries, and applications that are in our default install. And these customers still want the things they did in 2002: support, security, an ecosystem of apps and partners, and a predictable life cycle. Mode 1 customers are satisfied with those things alone.
But customers who stretching their IT further want more. Mode 2 requires:
  • Less disruptive updates
  • Greater automation
  • More available software
  • Less software installed
The first 2 things are pretty straightforward. Some systems can’t afford to go down, even to upgrade hardware. And automation and self-service are the backbone of today’s advanced dev environments. Tools that are coming into their own now like Chef, Puppet, Ansible, Cockpit, and even integrated management are a good start.
In 2002, the last 2 items might have seemed at odds–more but less. As Hellekson explained, customers want more choices but would like to see a base OS option that is far more lightweight and pared down. He also noted that many of the advancements made in recent years like the addition of Software Collections, the rise of the Atomic technologies, and the growth of containers are all approaches to minimizing the OS. What comes next will build on these existing works.
