After Years of Linux on ARM, when is the Year of Red Hat on ARM servers?

Bradley Roderick

From hobbyist SoC devices such as the ubiquitous Raspberry Pi to a complete domination of the mobile device market, ARM processors have proven the value of the architecture. It is easy to see why ARM processors were able to explode in this market, given that they are able to pack quite a bit of performance into a rather small physical space. Take for instance Qualcomm's Snapdragon 400 processor , which is used in many products including the Huawei Watch This...

What's new in MACsec: setting up MACsec using wpa_supplicant and (optionally) NetworkManager

Sabrina Dubroca

A few months ago, on this blog, we talked about MACsec . In this post, I want to introduce the work we've done since then. Since that work revolves around methods to configure MACsec, this will also act as a guide to configure it by two methods: wpa_supplicant alone, or NetworkManager with wpa_supplicant. If you read the previous MACsec post, you probably thought that this whole business of generating keys and creating "secure associations" isn't very convenient, especially given that...

Running HPC workloads across multiple architectures with Red Hat Enterprise Linux

Adrian Reber

In this article, I want to provide some background details about our recently developed demonstration video - “ Running Game of Life across multiple architectures with Red Hat Enterprise Linux “. This video shows the Game of Life running in a heterogeneous environment using three 64-bit hardware architectures: aarch64 (ARM v8-A), ppc64le (IBM Power little endian) and x86_64 (Intel Xeon). If you are not familiar with the rules of this cellular automaton, they are worth checking out via the reference...

The need for speed and the kernel datapath - recent improvements in UDP packets processing

Paolo Abeni

Networking hardware is becoming crazily fast, 10Gbs NICs are entry-level for server h/w, 100Gbs cards are increasingly popular and 200Gbs are already surfacing. While the Linux kernel is striving to cope with such speeds with large packets and all kind of aggregation, ISPs are requesting much more demanding workload with NFV and line rate packet processing even for 64 bytes packets. Is everything lost and are we all doomed to rely on some kernel bypass solution? Possibly, but let's first...

Fedora 14: Fedora to Red Hat Enterprise Linux

Putting technology in front of a wide audience quickly is part of the open source model, as seen in the 'release early, release often' mantra popular among open source developers. This community collaboration results in more feedback about feature functionality, and more opportunities for developers to continually improve code. Red Hat participates in this process as part of the Fedora community, and its contributions to Fedora help enhance the technology selected by Fedora's substantial user and contributor base. Fedora and Red Hat create a more scalable, extensible, and interoperable Red Hat Enterprise Linux.

Manage IT resources with cgroups (demo)

Senior Software Maintenance Engineer Neil Horman from Red Hat demonstrates cgroups, a generic mechanism the kernel provides for grouping of processes and applying controls to those groups. The grouping is done via a virtual filesystem called 'cgroup.' Within this filesytem, each directory defines a new group. Tunables within a cgroup are provided by what the kernel calls 'controllers.' Each controller is able to expose one or more tunable or control. When mounting the cgroups filesystem, it is possible to mount the filesystem several times, with each mount point having a different set of (non-overlapping) controllers. The key idea is that this allows the administrator to construct differing group hierarchies for different sets of controllers/tunables, which offers new ways to control and manage cloud resources.

Red Hat gives Adobe a flexible IT canvas

Adobe Systems, a long-time user of Red Hat® Enterprise Linux®, wanted to offer its enterprise customers easy access to sandbox resources to evaluate and prototype solutions using Adobe products. Turning to the cloud, Adobe used Red Hat Enterprise Linux and Amazon Web Services (AWS) to not only deliver a sandbox solution, but also to offer customers a Software- as-a-Service (SaaS) option for deploying Adobe-based solutions. Today, Adobe is using the Red Hat platform and Amazon Web Services to help customers simplify deployment, lower cost of ownership, and accelerate time to value.

Open Sourcing The Enterprise: Ten Years Of Red Hat Enterprise Linux

Red Hat Enterprise Linux transformed enterprise IT, and dramatically changed the software industry forever. By combining the open source development model with a customer-centric subscription based business model, Red Hat gave enterprise customers a way to leverage the value of open source in a way that made sense for them, and that spurred the adoption of Linux across the enterprise. But it wasn't easy. There were doubts and obstacles to overcome, customers and partners to convince, and millions of developers to collaborate with. But with commitment and vision, it all just worked.

Enabling JBoss for operations

Chris Morgan, senior product marketing manager at JBoss, explains how JBoss Operations Network (JBoss ON) makes managing applications simpler. Like a modern car dashboard, JBoss ON provides an integrated, easy-to-use collection of functional tools. And it's open source. Like Red Hat Enterprise Linux and Fedora, JBoss ON has a community version, Jopr, that provides bleeding-edge technology and the breeding ground for tomorrow's JBoss ON technologies. "Operations Network brings to life what's going on with JBoss." -- Chris Morgan See more Red Hat videos: http://www.redhat.com/videos/

Why I started using containers

Konrad Kleine

A few years back (2013-2016) I was working as a C++ Software Development Engineer at Intel on a monolithic product with a backend written in C++ and a web frontend written in Java. The product was shipped complete with hardware and as a VMware image. Internally we kept ISO CD images on a shared server for every released or QA approved version of the product. Built into the product was a very clever issue reporting mechanism that allowed us, developers...

The content of the previous post discussed creating the open-vm-tools container’s Dockerfile and automating its started up via systemd with a unit file. Open-vm-tools as a service might need to start before the docker runtime or even the network stack, this leads us to runc and system containers. If you’ve finished the first article you have a running open-vm-tools Docker container. docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5428906cd366 open-vm-tools "/bin/sh -c /usr/bin/" 13 seconds ago Up...
