When the first Linux distributions based on the 3.0 kernel were released almost a year ago, I was struck by how far Linux had advanced. The latest turn of the crank for Linux, in the form of Red Hat Enterprise Linux 7 (RHEL 7), reinforces this opinion. Built primarily on recent versions of the Linux 3.0 et seq kernel available to the entire Linux community, including SUSE, Red Hat, Cannonical and others, RHEL 7 continues the progress of the Linux community toward an OS that is fully capable of replacing proprietary RISC/UNIX for the vast majority of enterprise workloads. It is apparent, both from the details on RHEL 7 and from perusing the documentation on other distribution providers, that Linux has continued to mature nicely as both a foundation for large scale-out clouds as well as a strong contender for the kind of enterprise workloads that previously were only comfortable on either RISC/UNIX systems or large Microsoft Server systems. In effect, Linux has continued its maturation to the point where its feature set and scalability begin to look like and feel like a top-tier UNIX.
In addition to the required low-level plumbing – schedulers, memory management and file systems capable of keeping up with both high-volume transactions and operating effectively in large distributed clusters – Red Hat has also focused on features to improve the installation and management experience, thus directly reducing cost of ownership, following in the footsteps of other modern OS development trajectories.
Among the enterprise technology that caught my eye:
