Confidential computing is moving quickly. The foundation is already here: AMD SEV-SNP and Intel TDX have made it possible to run confidential virtual machines (VMs) with stronger protection for data in use. Ubuntu 26.04 Long Term Support (LTS) brings integrated host and guest support for both of these technologies, making confidential computing a native  part of the Ubuntu virtualization offering.. However, The next wave of features is still being developed and upstreamed.

Most organizations already understand encryption at rest and encryption in transit. These controls are mature, widely deployed, and often explicitly referenced in security frameworks. However, runtime is different: when an application processes sensitive information, that data is typically available in memory.

Meet Alex, an Android developer. Like many developers, Alex would rather spend the day building applications than managing devices, maintaining emulators, or hunting for the right test environment. Thankfully, Alex is using Anbox Cloud, which simplifies their workflows and keeps them focused on development. In this article, we’ll follow Alex through their day to show you how it works, from feature development to release.

The Enterprise Store makes software distribution manageable and scalable behind firewalls or in air-gapped environments. Available with an Ubuntu Pro subscription, the Enterprise Store respects the security protocols of strict environments, in a way that is controllable, auditable, and predictable. The Enterprise Store is an on-premise edge proxy.

Some memory leaks are straightforward to detect. A process allocates memory, forgets to free it, and grows until something breaks. This was not that kind of leak. This is the story of how Canonical Support helped a global retail organization trace the cause for an unusual memory leak originating in PID 1, the very first process started by the kernel during the system boot sequence. The memory footprint was 10 times higher than expected.

MAAS brings cloud-like automation to physical servers. It helps teams discover, commission, deploy, and repurpose machines from a central control plane, turning bare metal into a programmable resource. But to experience that value, users first need to get MAAS up and running. That path is now cleaner and easier to follow.
