  • Introduction to virtio-networking and vhost-net

    In this post we have scratched the surface of the virtio-networking ecosystem, introducing you to the basic building blocks of virtualization and networking used by virtio-networking. We have briefly covered the virtio spec and the vhost protocol, reviewed the frontend and backend architecture used for implementing the virtio interface and have taken you through the vhost-net/virtio-net architecture of vhost-net (host kernel) communicating with virtio-net (guest kernel).

    A fundamental challenge we had when trying to explain things was the historical overloading of terms. As one example, virtio-net refers both to the virtio networking device implementation in the virtio specification and also to the guest kernel front end described in the vhost-net/virtio-net architecture. We attempted to address this by explaining the context of terms and using virtio-net to only describe the guest kernel frontend.

    As will be explained in later posts, there are other implementations for the virtio spec networking device based on using DPDK and different hardware offloading techniques which are all under the umbrella of the virtio-networking.

    The next two posts are intended to provide a deeper understanding of the vhost-net/virtio-net architecture. One post will be intended for architects providing a technical deep dive into the vhost-net/virtio-net and explaining how in practice the data plane and control planes are implemented. The other post intended for developers will be a hands on session including Ansible scripts to enable experimenting with the vhost-net/virtio-net architecture.

    If you prefer high level overviews we recommend you keep an eye out for the virtio-networking and DPDK introductions, to be published in the upcoming weeks.

  • 3 Infrastructure Compliance Best Practices for DevOps

    For most IT organizations, the need for compliance goes without saying. Internal corporate policies and external regulations like HIPAA and Sarbanes Oxley require compliance. Businesses in heavily regulated industries like healthcare, financial services, and public service are among those with the greatest need for strong compliance programs.

The community-led renaissance of open source

With few commercial participants, early free software and open source communities were, by definition, community-led. Software was designed and created organically by communities of users in response to their needs and inspiration. The results, to a degree nobody predicted, were often magical. First-generation open source businesses like Red Hat emerged to respond to these needs. They combined the best of both worlds: the flexibility and control of raw open source with the commercial support that enterprises depend on. These new open source businesses found their opportunity by adding the missing—but necessary—commercial services to community-led open source projects. These services would be costly for organizations to provide on their own and potentially even more costly to do without. One early leader of that era, Cygnus Solutions, even adopted the counter-intuitive tagline "Making free software affordable." But back then, it was always overwhelmingly clear: The commercial vendors were in service of the community, filling in around the edges to enable commercial applications. The community was the star, and the companies were the supporting cast. Read more

Election fraud: Is there an open source solution?

Can open source technology help keep our elections honest? With its Trust The Vote Project, the Open Source Election Technology (OSET) Institute is working on making that a reality for elections in the United States and around the world. The project is developing an open, adaptable, flexible, full-featured, and innovative elections technology platform called ElectOS. It will support all aspects of elections administration and voting, including creating, marking, casting, and counting ballots and managing all back-office functions. The software is freely available under an Open Source Initiative (OSI)-recognized public license for adoption, adaptation, and deployment by anyone, including elections jurisdictions directly or, more commonly, commercial vendors or systems integrators.

Meld is an excellent file and folder comparison tool for Windows and Linux

Ever had two sets of the same files and folders and couldn't decide which one to retain? It may take a long time to actually open each to verify the one that's recent or the one you need; while dates associated with the files may help, they won't all the time as they don't tell you anything about the actual content. This is where file comparison tools can be time-savers. Meld is an open source file comparison tool for Windows and Linux for exactly that purpose. Read more
