Over the last couple of decades, a lot has changed in terms of how companies are running their infrastructure. The days of dedicated physical servers are long gone, and there are a variety of options for making the most out of your hosts, regardless of whether you’re running them on-prem or in the cloud. Virtualization paved the way for scalability, standardization and cost optimisation. Containerization brought new efficiencies.
IoT devices have become ubiquitous. Given the number of new devices being deployed all over the world and far from the desks of developers, it is imperative to have a solid set of tools to manage them without being directly connected to them via JTAG, USB, or SSH. The necessary tasks in the IoT device lifecycle include device deployment and management, remote monitoring, and over-the-air (OTA) software updates.
Cloud optimisation enables organisations to significantly lower their cloud spending while ensuring the desired performance and necessary compliance. It’s a process that every business should adopt when choosing cloud infrastructure as a foundation for their applications. It’s been proven that applying cloud optimisation best practices leads to a total cost of ownership (TCO) reduction of two-thirds under certain circumstances. But let’s step back for a second.
It’s a new year, and an especially great time to reflect on the security of your robots. After all, those interested in breaching it are probably doing the same. In previous articles, we discussed ROS security by detailing practical steps for securing your robots on Ubuntu and the challenges the community faces. In this blog post, I’ll give you some strategies, tips and open-source tools you can integrate into your development process today to ramp up the security of your project.
I/O wait is a plaguing issue in Linux. Speaking in layman terms, I/O wait is the time taken by the processor (here, CPU) to complete an input service request. Ideally, our CPU doesn't seem to do any work when it is processing one input request at a time, thus the duration between your input and the output provided by the system can be treated as the I/O wait time.
In a previous post, I explained how we made our Ubuntu image 15 times smaller by chiselling a specific slice of Ubuntu for.NET developers. In this blog, I will provide step-by-step instructions on customising your chiselled Ubuntu base images for any use case. I don’t believe in a perfect container base image anymore.
In this blog, I explain the idea behind Distroless container images, which inspired us to create chiselled Ubuntu images — adding the “distro” back to distro-less! In a follow-up blog, I will then provide a step-by-step example of how you can create your own chiselled Ubuntu base container images, built for your specific needs.
The popular open-source platform Kubescape by ARMO has been recently announced as a fully managed operator called a Charm for Canonical’s Charmed Kubernetes distribution. This collaboration between Canonical and ARMO is exciting for the solution it enables for end users, ultimately resulting in hardened and more secure Kubernetes environments.
Git is an open-source version control system that is used to store code and web content in repositories. Git was designed to facilitate collaborative projects between developers. But leveraging the power of Git via the command line can be challenging to master, so many developers choose to use GUI clients to make using Git commands and actions more visual and simple.
