Ubuntu Summit 26.04 is coming: Save the date and share your story!

Following the incredible success of Ubuntu Summit 25.10, we are thrilled to announce that Ubuntu Summit 26.04 is officially on the horizon. If you are new to the Ubuntu community, every new release of Ubuntu comes with an Ubuntu Summit – an event that takes place twice a year and serves as a showcase of the absolute best in open source innovation from around the world. Our hub in London hosts the talks, which are then streamed live, across the world.

How to manage Ubuntu fleets using on-premises Active Directory and ADSys

The “hybrid fleet” is today’s reality: organizations diversify operating systems while Microsoft Active Directory (AD) remains the dominant identity “source of truth.” IT administrators must ensure Linux machines, like Ubuntu desktops and servers, behave as first-class citizens in this environment.

Simplify bare metal operations for sovereign clouds

The way enterprises are thinking about their infrastructure has changed. Digital sovereignty of all kinds – data sovereignty, operational sovereignty, and software sovereignty – have begun to dominate the infrastructure discussion. Today, these abstract terms have become practical concerns for platform teams.

How to Harden Ubuntu SSH: From static keys to cloud identity

30 years after its introduction, Secure Shell (SSH) remains the ubiquitous gateway for administration, making it a primary target for brute force attacks and lateral movement within enterprise environments. For system administrators and security architects operating under the weight of regulatory frameworks like SOC2, HIPAA, and PCI-DSS, default SSH configurations are an “open door” that represents an unacceptable risk.

The "scanner report has to be green" trap

In the modern DevSecOps world, CISOs are constantly looking for signals in the noise, and the outputs of security scanners often carry a lot of weight. A security scan that returns a “zero CVE” report often unlocks promotion to production; a single red flag can block a release. This binary view of security has birthed two diametrically opposed philosophies. On one side, we have the long-term support (LTS) approach: stay on a battle-tested version and backport specific security fixes.

Hot code burns: the supply chain case for letting your containers cool before you ship

In September 2025, dozens of popular JavaScript packages, like chalk and debug, were compromised on the npm registry. These packages are so ubiquitous they end up in everything: front-end apps, back-end microservices, and CI tooling. Developers didn’t do anything wrong, they just ran the same command they always do: npm install chalk. But then the malware arrived silently. This wasn’t a bug in an operating system. It wasn’t a virus on someone’s laptop.

Introducing MicroCloud Cluster Manager

Today, we’re excited to introduce the beta release of MicroCloud Cluster Manager, a new way to discover, organize, and operate your MicroCloud environments from a single, unified interface. MicroCloud is an open source cloud platform that makes it simple to create lightweight, resilient clusters anywhere. As teams scale from one cluster to many, visibility and coordination quickly become essential. Cluster Manager is built to solve exactly that.

Building a dry-run mode for the OpenTelemetry Collector

Teams continuously deploy programmable telemetry pipelines to production, without having access to a dry-run mode. At the same time, most organizations lack staging environments that resemble production – especially with regards to observability and other platform-level services.

The bare metal problem in AI Factories

As AI platforms grow in scale, many of the limiting factors are no longer related to model design or algorithmic performance, but to the operation of the underlying infrastructure. GPU accelerators are key components and are responsible for a large part of the total system cost, which makes their continuous availability and stable operation critical to the output and efficiency of the entire AI platform.
