Understanding disaggregated GenAI model serving with llm-d

Apr 27, 2026 By Rob Gibbon In Canonical
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.

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

Apr 22, 2026 By Samir Kamerkar In Canonical
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.

Mar 31, 2026 By Massimiliano Gori In Canonical
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.

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

Mar 30, 2026 By Massimiliano Gori In Canonical
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

Mar 27, 2026 By Lech Sandecki In Canonical
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.
