Monitoring KSM (Kernel Same-page Merging) performance at deduping memory shared across VMs.

In the first part of this blog series, we discussed the run-time (in)security challenge, which can leave your code and data vulnerable to attacks by both the privileged system software of the public cloud infrastructure, as well as its administrators. We also introduced the concept of trusted execution environments and confidential computing, (CC), as a paradigm to address this challenge.

Users live in the sunlit world of what they believe to be reality. But, there is, unseen by most, an underworld. A place that is just as real, but not as brightly lit. The Kernel Parameter side (apologies to George Romero). Kernel parameters aren’t really that scary in actuality, but they can be a dark and cobweb-filled corner of the Linux world. Kernel parameters are the means by which we can pass parameters to the Linux (or Unix-like) kernel to control how that it behaves.

Welcome to Part II of this three-part mini-series on bridging the gap between operational technology (OT) and information technology (IT) in Industry 4.0. In Part I, we set the stage for the remainder of the series and gave an overview of IT and OT, the two technological layers of modern industrial factories. In this blog, we expand on that knowledge by confronting the two domains and discussing the automation pyramid concept.

You launch a startup or a new project in your organisation. You decide to use Amazon Web Services (AWS) as your primary cloud platform. You estimate costs based on listed prices, and rest assured that your startup/project will meet its budget. And then, suddenly, at the end of the month, you receive an invoice from AWS for an amount two times higher than you originally expected.

ERLANGEN, Germany, October 27, 2022 – Elektrobit and Canonical today announced a partnership to bring the benefits of Canonical’s Ubuntu operating system to automotive software. As the industry transitions towards software-defined vehicles, the new partnership will make it easier than ever before for car makers, suppliers, and developers to create the next generation of vehicle applications, while meeting stringent automotive standards.

Think open source – the world’s leading software portfolio. Open-source software enables you to build fully functional virtualisation and cloud infrastructure while ensuring total cost of ownership (TCO) reduction and business continuity. In this blog, we will walk you through the open source ecosystem. We will help you understand how it differs from other VMware alternatives by answering five common questions.

Google just announced that they have submitted an application for Kubeflow to become an incubating project in the Cloud Native Computing Foundation (CNCF). It is an initiative supported by the Kubeflow Project Steering group. The request is visible to everyone and it represents a game changer for the rhythm which Kubeflow will develop. It makes community growth a strategic objective and puts Kubeflow on a development fast track.

Welcome to this three-part mini-series on bridging the gap between operational technology (OT) and information technology (IT) in Industry 4.0. Throughout this series, we will discuss the key challenges industrial manufacturers face when trying to accelerate their digital transformation. We will understand why legacy update approaches and lack of security in OT do not suit the Industry 4.0 world and assess how adopting open source software can help bridge the gap.

OTA is a term commonly used when working with any type of device. Simply, the abbreviation OTA means ‘over-the-air’, and refers to the distribution of information wirelessly. In the context of IoT, you will often hear it used in combination with “updates”. Let’s explore in more detail what OTA is.
