Understanding disaggregated GenAI model serving with llm-d

llm-d is an open source solution for managing high-scale, high-performance Large Language Model (LLM) deployments. LLMs are at the heart of generative AI – so when you chat with ChatGPT or Gemini, you’re talking to an LLM. Simple LLM deployments – where an LLM is deployed to a single server – can suffer from latency issues, even with just one user. This can be because of lack of memory-bandwidth on the server, or because of KV cache pressure on system memory.

Canonical releases Ubuntu 26.04 LTS Resolute Raccoon

Today Canonical announced the release of Ubuntu 26.04 LTS, codenamed “Resolute Raccoon,” available to download and install from ubuntu.com/download. Resolute Raccoon builds on the resilience-focused improvements introduced in interim releases, with TPM-backed full-disk encryption, improved support for application permission prompting, Livepatch updates for Arm– based servers, and Rust-based utilities for enhanced memory safety.

From Jammy to Resolute: how Ubuntu's toolchains have evolved

The evolution of Ubuntu’s toolchains story goes beyond just providing up-to-date GCC, LLVM, and Python. It is also about opinionated openJDK variants, task-focused devpacks, FIPS compliant toolchains, and snaps, like the new.NET snap and Snapcraft plugin. These are enhancements that collapse half a day of setup into a single command or two, demonstrating what a frictionless developer experience means in practice for framework and application developers on Ubuntu.

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.
