If You Like Bonding, You Will Love Teaming

In this day and age, where almost everything is connected to the World Wide Web, the demands on networking (in general) are mushrooming. In the developed world it’s common to be able to get 20 megabits per second connections on our mobile devices and 50 megabits per second connections at home. By extension, the demands on enterprise data centers are even higher (by at least three to four orders of magnitude) – as these central “hubs” are where traffic from the aforementioned individual end nodes converge. Consider the act of flipping through a series of cloud-hosted HD photos on a mobile device – this can easily result in billions of packets being transferred (in fractions of a second).

The good news is that our networking interfaces are getting “bigger and faster.” 40 gigabit per second Ethernet is currently being deployed, and work to finalize on 100 gigbit per second end point interfaces is currently underway.

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.

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.

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.
