Debian 13 "Trixie"

Debian 13 “Trixie” on Azure

A production-ready Debian 13 (“Trixie”) Gen2 Linux image, built and hardened for the Azure Marketplace. This is the latest stable Debian release — newer kernel, newer toolchains, and the current security-patch baseline — for teams who want the freshest Debian rather than the longer-settled Debian 12 (“Bookworm”). Debian is the upstream Ubuntu is built on. This image gives you that newest base pre-integrated with Azure and certified to Microsoft Marketplace standards.

Who this is for: Platform engineers, ISVs, and operators who want the most recent stable Debian kernel and userland on Azure, teams validating workloads against the current Debian release ahead of a wider rollout, and anyone running Trixie on-prem who wants one consistent OS across cloud and edge.

Target industries & use cases: Financial services, healthcare, government, telecom, retail, and regulated environments that require reproducible, audited Linux base images. Common workloads: web hosting (Apache, nginx, Caddy with PHP-FPM, Node.js), containerized applications (Docker, Podman, Kubernetes nodes), database servers (PostgreSQL, MariaDB, MongoDB, Redis), and CI/CD runner hosts that benefit from current kernel features.

Value proposition: Provisioning a secure Debian 13 host on Azure normally means installing the Azure Linux Agent, configuring Trusted Launch, applying current kernel CVEs, and validating against Marketplace certification. This image does all of that for you:

• Monthly patch cadence — each version is rebuilt from upstream Debian security updates within days of release, keeping you on the latest stable kernel
• 33 documented hardening traps applied — every published version is gated through an automated trap-audit covering Trusted Launch, sysprep race conditions, Defender pre-installation, hardening-script residue, and 29 more
• Trusted Launch + Secure Boot enabled by default — Gen2 image with vTPM and signed-boot configured per Microsoft’s OEM requirements
• Azure Linux Agent pre-installed and pre-configured — walinuxagent.service is running; custom-script and run-command work on first boot
• Audit trail per release — build provenance and certification evidence retained per version

How this differs from rolling your own: The public Debian cloud image is fine for a single dev VM but lacks the Azure-specific hardening (root SSH disabled, password auth disabled, audit logging configured, serial-console exposure closed) that production needs. If you want the longer-settled release instead, our Debian 12 (“Bookworm”) image shares the same operational playbook; this Trixie image tracks the newest stable Debian.

Recommended deployment: Standard_D2as_v5 or larger for general-purpose web and container workloads; Standard_E2as_v5 or larger for memory-heavy databases. Premium SSD v2 for data disks. Front public web workloads with Azure Application Gateway. SSH key authentication required.

Azure integration: Azure Linux Agent, Trusted Launch + Secure Boot, Azure Monitor Agent, Azure Backup, Azure Disk Encryption, Azure Defender for Servers, and Azure VM Run Command all attach via standard extensions. Debian is free and open-source; standard Azure compute and storage rates apply.
