Variations
Choose the operating system, cloud and version you need. Every variation is the same hardened Debian image, built and supported by cloudimg.
Overview
Debian (Bookworm) is a stable release of the Debian Linux distribution, with a proven kernel, toolchain and package set from one of the oldest and most widely used community distributions. This is the native 64-bit Arm (AArch64) build, made to run on Arm virtual machines, where the same workloads often cost less to run than on x86 for the same performance. It gives you a stable, minimal foundation for application hosting, container platforms and cloud native workloads on Arm.
This image is a clean, fully patched Debian 12 Arm foundation to build your own services on, with no subscription, no licence key and no default credential.
Why the cloudimg image
The cloudimg image is a hardened Debian 12 Arm base with every available security update applied at build time and unattended security updates armed, so instances keep patching themselves. No credential is baked in: access is by the SSH key you choose at launch, and the machine identity and SSH host keys are regenerated uniquely on every instance, so no two machines share a secret. Password login is disabled, root password login is off, and AppArmor stays enforcing. A paired deployment guide tested against the exact image is included, and every instance is backed by 24/7 cloudimg support.
Common uses
- A cost efficient Arm base for application hosting and web services
- Container platforms and cloud native workloads on Arm virtual machines
- A stable, minimal community-distribution foundation for your own stacks on Arm
