  • Linux 4.12 Network Performance Issues With Virtio

    We recently encountered a server problem that was a little more than just a configuration mishap, and we had to dig deeper. Here’s the story:

  • The search for the killer app of unikernels

    When a radically different technology comes along it usually takes time before we figure out how to apply it. When we had steam engines running factories there was one engine in each factory with a giant driveshaft running through the whole factory. When the electric engine came along people started replacing the giant steam engine with a giant electric motor. It took time before people understood that they could deploy several small motors in different parts of the factory and connect electric cables rather than having a common driveshaft. It takes time to understand the technology and its applicability.

  • AWS No Longer a Holdout, Joins Kubernetes Group

    It's only been two weeks since Microsoft made news by signing up as a platinum member of the Cloud Native Computing Foundation, a Linux Foundation project and the organization behind the open source container orchestration platform Kubernetes. At the time, that made Amazon Web Services the only major public cloud provider that wasn't a member, and it wasn't expected to sign on anytime soon because it has its own container orchestration platform, Elastic Container Service.

    Introduced as part of LunarG's recent Vulkan SDK update is the VLF, the Vulkan Layer Factory. The Vulkan Layer Factory aims to creating Vulkan layers easier by taking care of a lot of the boilerplate code for dealing with the initialization, etc. This framework also provides for "interceptor objects" for overriding functions pre/post API calls for Vulkan entry points of interest.
