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.

Red Hat Enterprise Linux 7 Release Candidate & Red Hat Enterprise Linux Atomic Host


For those not attending Red Hat Summit 2014 or not tracking the latest news and updates (available on the official Red Hat Summit Blog), you may have missed two important and exciting announcements, namely:

  • A Red Hat Enterprise Linux 7 Release Candidate (RC) will be made publicly available (starting next week).  As a pre-release build of Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 7 RC offers a near-final look at the only operating system crafted for the open hybrid cloud, building upon the feedback collected during the beta program for Red Hat Enterprise Linux 7.
  • Also, Red Hat plans to introduce Red Hat Enterprise Linux Atomic Host as a new addition to the Red Hat Enterprise Linux family.  Red Hat Enterprise Linux Atomic Host couples the flexible, lightweight and modular capabilities of Linux Containers with the reliability and security of Red Hat Enterprise Linux in a reduced image size that will enable easy movement of Red Hat Enterprise Linux-certified applications across bare metal systems, virtual machines and private and public clouds.

For more information on either the Red Hat Enterprise Linux 7 RC or our plans for Red Hat Enterprise Linux Atomic Host – I encourage you to visit: press.redhat.com

Red Hat CEO and President Jim Whitehurst kicked off the 2014 Red Hat Summit, celebrating 10 years of growth and innovation. Whitehurst addressed a crowded ballroom at Moscone Center South. “You are all part of our mission statement,” he said.

This year’s Summit theme, ADVANCE, speaks to Red Hat’s mission statement, and about the commitment Red Hat has made to partners, customers, and many communities: to advance the state of IT to meet demand.

In the spirit of innovation, Whitehurst acknowledged the Innovation Awards–an annual event highlighting innovative Red Hat customers. He invited attendees—and you—to vote for the Innovator of the Year, who will be announced at the Summit on April 17, 2014.

A tale of some cities

Whitehurst, a fan of history (and analogies), took us back to September 2, 1666: the Great Fire of London. A terrible event–but…

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.

Springing to the Summit


For anyone living in the northern hemisphere – I have some good news: spring is coming.  Spring brings with it a lot of excitement, especially as the changing seasons mean that Red Hat will soon be hosting its annual Summit at the Moscone Center in San Francisco, California (April 14th to 18th).

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:

Introducing kpatch: Dynamic Kernel Patching


In upstream development news, the kernel team here at Red Hat has been working on a dynamic kernel patching project called kpatch for several months.   At long last, the project has reached a point where we feel it’s ready for a wider audience and are very excited to announce that we’ve released the kpatch code under GPLv2.

kpatch allows you to patch a Linux kernel without rebooting or restarting any processes.  This enables sysadmins to apply critical security patches to the kernel immediately, without having to wait for long-running tasks to complete, users to log off, or scheduled reboot windows.  It gives more control over uptime without sacrificing security or stability.
