Managing a Kubernetes cluster is a complex endeavor. As demands on a cluster grow, increasing the number of deployed pods can help ease the load on the system. But what do you do when you run out of nodes to host those pods, or when the load decreases and some nodes are no longer needed? Manually adding or removing nodes is possible, but wouldn’t it be better if there was a way to automate that task? Fortunately, that’s exactly what the Kubernetes Autoscaler charm is for!

Sometimes a hat is just a hat, the truth is just the truth, and the clearly most popular example of a category is plain to see. In this case, Ubuntu is the most popular Linux distribution currently available. With the operating system’s superior popularity also comes an amazing amount of community support.

Technology plays a strategic role in the success of any organisation. Whether you’re part of an enterprise with thousands of employees across the globe or running a startup from the garage of your home, the success of the business comes down to how you consume technology. However, it’s not that straightforward, and IT decision makers usually have to make a lot of trade-offs when investing in technology.

Welcome to the concluding chapter of this journey on embedded Linux development with Ubuntu. We covered a lot of ground, so let us quickly recap what we learned so far. In Part I we introduced Snaps, software packages designed for the world of IoT. Snap packages isolate and encapsulate an entire application, increasing the security and stability of embedded devices. Snapcraft is the command-line tool to build snaps.

Linux Active Directory integration is one of the most popular and requested topics from both the community and our clients. On May 17 we delivered a webinar on the new AD integration features introduced with 22.04 (now available on demand) and following that we received an overwhelming number of questions. In this blog post we would like to address directly the most frequent ones

Welcome to Part II of this three-part mini-series on embedded Linux development on Ubuntu. In Part I, we set the stage for the remainder of the series and gave an overview of snaps, the packaging format at the heart of embedded devices running Ubuntu. Snaps are a secure, confined, dependency-free, cross-platform Linux packaging format. Software publishers often want to manage their application components using containers.

Welcome to this three-part mini-series on embedded Linux development on Ubuntu. Throughout this series, we will discuss the key challenges of traditional software distribution mechanisms for embedded Linux devices. We will understand why legacy development and update approaches do not suit the Internet-of-Things (IoT) world and assess how Ubuntu simplifies and secures embedded Linux development.

Canonical’s UA and Pro customers can now fully benefit from their subscriptions directly in containerised environments and pipelines. The new UA client release (27.7+) makes it easier to enable FIPS mode in Ubuntu containers. It also automatically signs up CI/CD builds for 10-year security updates to never worry about production container images getting timely patches for high and critical CVEs.
