Linux is one of the best known and most used open source operating systems. The key advantages of using Linux servers are that they are stable, secure, compatible, and customizable.

MicroK8s was first released in late 2018 and has seen significant adoption rates from developers and enterprises alike ever since. Taking increasing demand and curiosity around the topic, we have already given an introduction to MicroK8s as well as covered how to deploy MicroK8s locally in previous blog posts. This time, we’ll take a look at MicroK8s’ applied value, by examining common MicroK8s use cases. Among others, this includes AI/ML workflows.

Just like countless other business functions, cloud delivery has now shifted entirely to remote working for now and perhaps longer term. Canonical has been a remote-first company for some time, so we thought we’d take this opportunity to share some of the best practices we’ve learned along the way. Communication Effective communication between customers, engineers, and project managers is the most critical element of successful cloud delivery.

15 July 2020: Canonical, the publisher of Ubuntu, today announces the launch of its enhanced Global System Integrator (GSI) Programme. Alongside new partnership benefits, it includes resell and integration opportunities for the entirety of Canonical’s secure, open source portfolio for the data centre, multi-cloud, edge and IoT.

Robotics@Canonical puts a strong focus on the migration from ROS to ROS 2. ROS 2 benefits from many improvements, especially robot security. Our goal is to make it easy for you to transition to ROS 2, whether you’re completely new to ROS or a seasoned engineer retooling for a new environment. Your new platform should be secure-by-default, and we expect you’ll need to pivot between different environments as you migrate from ROS to ROS 2.

The easiest way to get started with Icinga is a single-node installation. If you are new to the Icinga world, here you have a kickstart for installing Icinga 2, Icinga Web 2 and Icinga Director on CentOS 7. With these steps you will have a ready Icinga environment for monitoring your infrastructure.

Metrics and logs go together like cookies and milk. Metrics tell you when you have a problem, and logs/events often tell you why that problem happened. But it’s always been harder than it needed to be to get both types of data onto a single screen, especially when the sysadmins using the tools aren’t necessarily daily experts in managing those monitoring platforms.

Out-of-memory (OOM) errors take place when the Linux kernel can’t provide enough memory to run all of its user-space processes, causing at least one process to exit without warning. Without a comprehensive monitoring solution, OOM errors can be tricky to diagnose. In this post, you will learn how to use Datadog to diagnose OOM errors on Linux systems.

High availability (HA) for MicroK8s, the lightweight Kubernetes, is now available as a tech preview for Linux, Windows and macOS. The Kubernetes control plane can now be distributed across multiple nodes, bringing resiliency to the cluster while maintaining a low footprint using Dqlite, the distributed SQL engine as the Kubernetes datastore.

ROS, Ripple and reflections – In this month’s edition of The State of Robotics, we’ll tell you about the recently discovered Ripple vulnerability, the latest and greatest in robots reflecting nature, and a dash of news from the ROS universe.
