For many organizations, IT modernization begins with the operating system. In the last few years, migrating workloads to Linux from RISC systems has accelerated as organizations seek to take advantage of the potential price/performance advantage of x86 blade hardware solutions. However, as open source becomes more pervasive, many enterprises are realizing additional benefits. Not only can enterprises reduce (or in some cases eliminate) their reliance on legacy systems by

We’re adopting a new marketing mantra for Red Hat Enterprise Linux: Listen. Learn. Build. Which probably doesn’t seem all that revolutionary. That’s pretty much the mantra of open source. But compare that to how tech marketing usually happens.
There’s a lot of building–assets and advertisements and the whole nine yards. But the listening and learning parts usually happen afterwards, if at all.
So we’re making a conscious effort to explicitly apply the principles of open source to the way that we market our flagship open source technology. We’re starting with the listening part.
And who exactly are we listening to? You.
And what exactly are we listening to you talk about? Your OS adventures.
And what exactly do we mean by “OS adventures”?–
–Actually, here’s a better idea. Instead of telling you what we’re doing and why, let’s show you…

Most people don’t consider their average USB memory stick to be a security threat. In fact, in a social engineering experiment conducted in 2016 at the University of Illinois and detailed in this research paper, a group of researchers dropped 297 USB sticks outside in the parking lot, in the hallway, and classrooms. Of the 297 USB sticks dropped,

Twice a year the most prominent supercomputing sites in the world get to showcase their capabilities and compete for a Top500 spot. With Linux dominating the list, Red Hat is paying close attention to the latest changes that will be announced at International Supercomputing (ISC) show in Frankfurt, Germany between June 18 to June 22, 2017.
While supercomputers of the past were often proprietary, the trend of building them out of commodity components has dominated the landscape in the past two decades. But recently the definition of “commodity“ in HPC has been morphing. Traditional solutions are routinely augmented by various acceleration technologies, cache-coherent interconnects are becoming mainstream and boutique hardware and software technologies previously reserved for highly specialized solutions are being adopted by major HPC sites at scale.
Developing new and adapting existing highly scalable applications to take advantage of the new technological advances across multiple deployment domains is the greatest challenge facing HPC sites. This is where the operating system can provide

In the world of heterogeneous data centers – having multiple operating systems running on different hardware platforms (and architectures) is the norm. Even traditional applications and databases are being migrated or abstracted using Java and other interpreted languages to minimize the impact on the end user, if they decide to run on a different platform.
Consider the common scenario where you have both Windows and Linux running in the data center and you need your Linux application to talk to Microsoft SQL Server and get some existing data from it. Your application would need to connect to the Windows server that is running the SQL Server database using one of many available APIs and request information.
While that may sound trivial, in reality you need to: know where that system is located, authenticate your application against it, and pay the penalty of traversing one or more networks to get the data back – all while the user is waiting. This, in fact, was “the way of the world” before Microsoft announced their intent to port MS SQL server to Linux in March of 2016. Today, however, you have a choice of having your applications connect to a Microsoft SQL Server that runs on either Windows or Linux

Since the Red Hat Enterprise Linux Server for ARM Development Preview 7.3 became available I’ve been wanting to try it out to see how the existing code for x86_64 systems works on the 64-bit ARM architecture (a.k.a. aarch64).
Going in, I was a bit apprehensive that some kind of heavy lifting would be needed to get things working on the ARM platform. My experience with cross-architecture ports with other distros (before I joined Red Hat) indicated

This is my last post dedicated to the use of Identity Management (IdM) and related technologies to address the Payment Card Industry Data Security Standard (PCI DSS). This specific post is related to requirement ten (i.e. the requirement to track and monitor all access to network resources and cardholder data). The outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.
Requirement ten focuses on audit and monitoring. Many components of an IdM-based solution, including client components like

If you have ever wanted to learn about Red Hat’s involvement in the ARM server ecosystem, and are in the San Francisco Bay Area, this week may be a perfect opportunity. Red Hat will be exhibiting at ARM TechCon, ARM Holdings’ premier yearly show at the Santa Clara Convention center. Attendees will be presented with a variety of great technical sessions and training topics, along with expert keynotes, solutions-based Expo Theater sessions and an expo floor filled with new and emerging technologies for the datacenter. Note that the expo floor can be accessed with the free

Linaro has announced a new project focused on IoT – LITE, or Linaro IoT and Embedded. This project will focus on developing core technology to be used in IoT devices and gateways.
Linaro is a consortium focused on the Linux ecosystem for ARM based systems — see www.linaro.org for details. Much of their work to date has been focused on Android phones and tablets. Active development efforts include server and networking as well as Digital Home. The Digital Home project focuses on set-top boxes and home gateways. Linaro’s goal is to avoid fragmentation of the ARM ecosystem by providing a common foundation that can be used to build a wide range of value-added applications.
LITE extends existing Linaro projects by addressing both

The concept to save (i.e. checkpoint / dump) the state of a process, at a certain point in time, so that it may later be used to restore / restart the process (to the exact same state) has existed for many years. One of the most prominent motivations to develop and support checkpoint/restore functionality was to provide improved fault tolerance. For example, checkpoint/restore allows for processes to be restored from previously created checkpoints if, for one reason or another, these processes had been aborted.
Over the years there have been several different implementations of checkpoint/restore for Linux. Existing implementations of checkpoint/restore differ in terms of “what level” (of the operating system) they are operating; the lowest level approaches focus on implementing checkpoint/restore directly in the kernel while other “higher level” approaches implement checkpoint/restore completely in user-space. While it would be difficult to unearth each and every approach / implementation – it is likely fair to
