Red Hat Unveils Red Hat Enterprise Linux 7

Six months ago we announced the beta availability of Red Hat Enterprise Linux 7. Two months ago, at Red Hat Summit 2014, we announced the availability of a release candidate for Red Hat Enterprise Linux 7. All the while we have been validating what’s new, different, and exciting about what Red Hat Enterprise Linux 7 has to offer – including:

Today we are pleased to announce the general availability of Red Hat Enterprise Linux 7, the latest major release of our flagship platform. As stated in this morning’s press release:

Red Hat Summit 2014: Interview with Tim Burke (VP of Infrastructure Engineering)

Earlier this morning, Richard Morrell (@EMEACloudGuy) posted his interview with Tim Burke, VP of Infrastructure Engineering, from Red Hat Summit 2014.  Listen here as Tim describes the evolution of Red Hat Enterprise Linux and how infrastructure continues to evolve to meet the needs of developers, new innovations like OpenStack and OpenShift, and even new requirements from segments like telecommunications and financial services.

Richard’s podcasts are also available via iTunes, podfeed.net, and Stitcher.

Mitigate TCP SYN Flood Attacks with Red Hat Enterprise Linux 7 Beta

Distributed Denial of Service (DDoS) attacks are becoming increasingly commonplace as business becomes more and more dependent on delivering services over the Internet.  One of the most common types of DDoS attacks is the well-known SYN-flood attack. It is a basic end-host resource attack designed to bring your server to its knees.  As a result, your server is unable to properly handle any new incoming connection requests.

Recently at DevConf.cz 2014, I gave a talk focusing on how you can survive TCP SYN-flooding attacks by implementing some recently developed kernel level Netfilter/iptables defense mechanisms. In this post I will provide a more condensed version of the talk highlighting how you can use these same techniques to protect your servers running Red Hat Enterprise Linux 7 Beta.

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.

OpenLMI @ Red Hat Summit 2014

OpenLMI will be represented at the upcoming Red Hat Summit, which is being held in San Francisco from April 14-17.

Stephen Gallagher and I will be giving a talk on OpenLMI, the new Linux Management Infrastructure, on Tuesday, April 15, at 10:40am. This talk will provide an overview of OpenLMI, cover its functional capabilities, and demonstrate using the LMIShell CLI and Scripts to accomplish common management tasks.

Red Hat Enterprise Linux: Beyond the World Records

In a recent post, we reviewed the 10 world record results set by Red Hat Enterprise Linux on the Intel Xeon processor E7 v2 family.  Besides showcasing the extreme capabilities of Red Hat Enterprise Linux, these performance achievements tell another compelling story – Red Hat Enterprise Linux has become an exceedingly popular choice when it comes to tough workloads.

For example, consider the share of Red Hat Enterprise Linux versus other operating systems used to produce these records. Out of 20 world record benchmark results (22 total submissions, 3 results were tied) posted by eight different OEM partners at the Intel Xeon processor E7 v2 family announcement, Red Hat Enterprise Linux was used in 12. Seventy-five percent of the hardware vendors taking part in this process chose to publish their world record benchmarks on the new family of processors using Red Hat Enterprise Linux. The chart below shows the significance of this adoption.

Red Hat Enterprise Linux Powers Scalable Computing Platforms with 10 New World Record Benchmarks

We’ve often talked about how Red Hat Enterprise Linux was fueling top benchmark results on the latest generation of Intel Xeon processors.

Today, we’re pleased to say that Red Hat Enterprise Linux has again demonstrated how an OS platform can handle the rigors of highly multi-threaded processing and on-demand scaling. In the most recent set of benchmarks done with one of the latest cutting edge processors, the Intel Xeon processor E7 v2 family, Red Hat Enterprise Linux claims 10 new world records. Here are these leading results at a glance:

Is Red Hat Enterprise Linux 7 Beta “The 7th Guest”?

Someone out there “gets” the title, right?  No, I’m not suggesting that Red Hat Enterprise Linux 7 Beta is an interactive puzzle adventure game. The relationship, I suppose, is in fact based on a much looser association: this is our seventh major release and this post (as opposed to my first) is dedicated to Red Hat Enterprise Linux running as a guest on third party hypervisors.
