Final Red Hat Enterprise Linux 5 Beta Now Available

When Red Hat Enterprise Linux 5 was first introduced in 2007, it was done so with an expected seven year lifecycle. Five years later, in 2012, we saw the continued strong adoption of Red Hat Enterprise Linux 5 and decided to extend its seven year lifecycle to 10 years. Now, in 2014, the original retirement year for Red Hat Enterprise Linux 5, we still see an active, dedicated customer base that has come to value this long, predictable lifecycle in addition to the platform’s inherent security, stability, and reliability.

Today, we are pleased to announce beta availability of Red Hat Enterprise Linux 5.11. This release continues to provide system administrators with a secure, stable, and reliable platform for their organization’s enterprise applications.

The Application Apartment Complex: Red Hat Enterprise Linux & Linux Containers

The advent of any new technology tends to generate a lot of excitement.  Over the course of my career, however, I have never experienced “a buzz” like what we are seeing around Linux containers and application packaging and isolation, containerized applications built in the Docker format.  From my perspective, the ways in which containers may influence our ever evolving technological ecosystem are, quite possibly, limitless…okay, limitless may be strong, and while “game changing technology” may sound cliche, it’s not far from the truth in this case.

KVM Virtualization: Refining the Virtual World with Red Hat Enterprise Linux 7 Beta

Ever since Red Hat Enterprise Linux added KVM Virtualization as a kernel-based hypervisor to run virtual machines (way back in Red Hat Enterprise Linux 5.4), the operating system took on a dual personality.

Red Hat Enterprise Linux became both a Virtualization host for high density virtual data centers / cloud service platforms, and a guest operating system running on third party hypervisors such as VMware vSphere and Microsoft Hyper-V. As the topic is sufficiently broad, I plan to split my discussion of virtualization into two posts.

Today’s post will discuss Red Hat Enterprise Linux 7 beta as a hypervisor using KVM Virtualization technology and it will highlight a few key enhancements that make Red Hat Enterprise Linux the operating system of choice for modern hybrid data centers. While the features that I will review are inherently those that I find to be the most exciting (note: I’m hoping you will find them to be exciting and useful as well), a complete list is available in the Red Hat Enterprise Linux 7 beta release notes.

Network Management, Bandwidth, and Security

It’s difficult to overestimate the importance of networking in today’s business environment. Since networking provides a central means for data exchange and collaboration, it is often a critical factor when it comes to determining an organization’s ultimate potential for success.

At Red Hat, we understand the importance of networking and the role it plays in maintaining business continuity. As such, we made networking one of the primary focus areas of development for Red Hat Enterprise Linux 7. Having incorporated numerous enhancements and performance optimizations into the Red Hat Enterprise Linux 7 beta – I’d like to take this opportunity to talk about “what’s new” with respect to improvements in network management, bandwidth, and security.
