Overview

Ubuntu Server 24.04 LTS is the current long term support release of the Ubuntu Linux distribution, with a modern kernel, toolchain and package set and security maintenance to 2029. 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, modern foundation for application hosting, container platforms and cloud native workloads on Arm.

This image is a clean, fully patched Ubuntu 24.04 LTS 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 Ubuntu 24.04 LTS 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, modern long term support foundation for your own stacks on Arm
