  • Your OpenStack Cloud Is Only As Good As The Linux You Install It On

    OpenStack services and drivers require a robust and integrated Linux operating system for top-performing functionality.

    OpenStack is not (just) an operating system; it’s cloud infrastructure.

    Open source developers and technologists from around the world collaborate on OpenStack to create infrastructure and tools for building and managing public and private clouds. According to the overview provided by the OpenStack Foundation, OpenStack is a “cloud operating system” that is designed to control and manage large pools of compute, storage, and networking resources.

    In more practical terms, OpenStack is a framework of at least 10 independent core services that all function together as the foundation for cloud infrastructure. At its very basic level, OpenStack is a set of services provided via a group of Python-written scripts that work in conjunction with another. Like any script, service, or plugin, they require an operating system (OS) to run, function, and perform. In OpenStack’s case, the OS of choice is Linux.

  • The Basics: Explaining Kubernetes, Mesosphere, and Docker Swarm

    Containers, a lightweight way to virtualize applications, are an important element of any DevOps plan. But how are you going to manage all of those containers? Container orchestration programs—Kubernetes, Mesosphere Marathon, and Docker Swarm—make it possible to manage containers without tearing your hair out.

    Before jumping into those, let's review the basics. Containers, according to 451 Research, are the fastest growing cloud-enabling technology. The reason for their appeal is that they use far fewer system resources than do virtual machines (VMs). After all, a VM runs not merely an operating system, but also a virtual copy of all the hardware that the OS needs to run. In contrast, containers demand just enough operating system and system resources for an application instance to run.

  • What's the difference between NFV automation and NFV orchestration?

    NFV automation is the ability to transfer manual network configuration to technology; NFV orchestration creates the deployment and automation blueprint.

  • AT&T, Intel, Google, Microsoft, Visa, and More to Speak at Open Networking Summit 2017

    The Linux Foundation has announced keynote speakers and session highlights for Open Networking Summit, to be held April 3-6, 2017 in Santa Clara, CA.

    ONS promises to be the largest, most comprehensive and most innovative networking and orchestration event of the year. The event brings enterprises, carriers, and cloud service providers together with the networking ecosystem to share learnings, highlight innovation and discuss the future of open source networking.

  • Developing open source software defined standards

    The Open Networking Foundation (ONF) is announcing its new Open Innovation Pipeline made possible through the aligned operations of ONF and Open Networking Lab (ON.Lab) as these two organizations finalize their pending merger.

    ON.Lab, with CORD and ONOS, successfully brought together operators, vendors and integrators to build solutions for carrier networks by leveraging SDN, NFV and Cloud technologies through an open source approach to solution creation. Operators have embraced the approach, and the industry is in the midst of a resulting transformation revolutionizing how solutions will be built for 5G mobile, ultra broadband and other next-generation networks.

IT development in the federal government has earned its reputation for being a painfully slow process but, the government’s cloud application platform, is helping to change that by standardizing the application lifecycle and helping to document it every step of the way. The need to document the entire stack of an IT solution in the federal government can run up to 1,000 pages, and that process requires in depth knowledge of thousands of pages of regulations, laws and risk management policies. Typically, federal agencies have compliance experts who must review this documentation and grant approval or request changes. This can take six to 14 months to get authority to operate (ATO), and then you still need to deploy the application.

Developer survey shows Linux as more popular than Windows

Every year since 2010, Stack Overflow conducts a developer survey where they ask the developer community about everything from their favorite technologies to their job preferences. The results of the eighth annual survey, held in January 2018, are out and not surprisingly, this year marks the largest number of respondents ever. Over 100,000 developers took the 30-minute survey revealing how they learn new technologies, which tools they use to get their work done, and what they look for while hunting some job. Read more

Ubuntu Preps to Remove Qt 4 Support from the Archives, Target Ubuntu 19.04

With Qt 5 being largely adopted by Qt application developers and other major projects, such as the KDE Plasma desktop environment, the Qt 4 technologies are becoming obsolete, so more and more GNU/Linux distributions plan its complete removal from the software repositories. Debian Project's Qt/KDE teams are already preparing to remove Qt 4 support from the repositories of the upcoming Debian GNU/Linux 10 "Buster" operating system series mainly because it's getting harder and harder to maintain it now that it is no longer supported upstream, and may cause lots of problems system-wide.
