Canonical has taken a firm step toward the future with Ubuntu, strengthening its support for Arm64 architectures and making a solid commitment to the Rust language in critical system components. This move is no coincidence: it responds to the growing demand for Arm servers, which according to recent data already represent nearly half the market, and to the need for more secure and efficient systems. The company is transforming Ubuntu into a first-class platform for Arm devices, from servers to laptops and embedded systems, while the adoption of Rust aims to eliminate classic memory vulnerabilities in essential tools such as the NTP daemon or the cp command.
On the Arm64 front, Canonical has integrated live kernel patching for Arm systems in Ubuntu 26.04 and Ubuntu Core 26, a feature previously exclusive to x86 that is crucial for server environments where rebooting is costly. In addition, the availability of native Arm64 Snap packages, including Steam with FEX emulation, brings the desktop ecosystem closer to this architecture. Moving Arm64 packages from the specialized ports.ubuntu.com server to the main archive.ubuntu.com repository streamlines global distribution and allows mirrors worldwide to serve these versions. This involves deep changes in build scripts and exposed bugs, such as one in cloud-init, but demonstrates the maturity of the support.
In parallel, Canonical is betting on Rust to replace traditional C components. The company has become a Gold sponsor of the Trifecta Tech Foundation, which develops ntpd-rs and sudo-rs. Although the transition is not without issues —a bug in the Rust-written cp command forced a temporary reversion to the classic GNU version— the strategy continues. Rust promises to eliminate memory management errors, a common source of security breaches, and Canonical aims to make Ubuntu the reference distribution in terms of robustness.
For businesses, this evolution has direct implications. A more secure operating system optimized for Arm allows deploying custom solutions with greater confidence. At Q2BSTUDIO, as a software and technology development company, we see in this movement an opportunity to build custom software applications that take advantage of the energy efficiency of Arm processors, especially in cloud and edge computing environments. The combination of Ubuntu with Rust, for instance, facilitates the creation of secure and lightweight microservices, ideal for deployments on AWS or Azure.
The rise of Ubuntu Arm64 also benefits artificial intelligence. Many edge devices and inference servers use Arm chips due to their low power consumption. With first-class support, AI workloads run more stably. At Q2BSTUDIO we integrate AI agents into corporate platforms, and having a robust base system is essential to guarantee low latency and high availability.
Cybersecurity is also strengthened. Rust reduces the attack surface in critical components such as the time system (NTP) or shell commands. This is key for companies that handle sensitive data and seek compliance with regulations like GDPR or ISO 27001. At Q2BSTUDIO we offer cybersecurity services (pentesting, audits) that benefit from a more reliable underlying operating system. Moreover, Business Intelligence tools like Power BI can be deployed on Ubuntu Arm with full confidence, leveraging cloud scalability.
Canonical has also improved support for Arm laptops beyond Qualcomm SoCs, with concept images for hardware based on CIX P1, already used in boards like Radxa and Orange Pi, and even in a Framework laptop motherboard. This opens the door for developers and companies that need lightweight yet powerful workstations for testing and development. The integration of Widevine DRM through Chrome for Arm64 Linux allows native playback of protected content (Netflix, Spotify), something that was previously a hurdle.
From a software development perspective, Canonical's bet on Rust and Arm64 simplifies packaging and deployment. Arm64 snaps are now downloadable from main mirrors, accelerating updates. For teams working with agile methodologies and needing fast iteration, this infrastructure is an enabler. At Q2BSTUDIO we accompany our clients in the migration to modern architectures, whether adapting existing applications or creating new ones from scratch with a cloud-native approach.
In summary, Ubuntu is undergoing a transformation that combines performance, security and versatility. The commitment to Arm64 and Rust is not only technical but strategic. Canonical understands that the future of computing involves heterogeneous architectures and languages that offer security guarantees from the compiler. For companies seeking to innovate without compromising stability, now is the ideal time to explore these capabilities. And on that path, having a technology partner like Q2BSTUDIO, with experience in custom applications, cloud, AI and cybersecurity, can make the difference between a complex adoption and a smooth transition.
