Canonical produces a variety of cloud-specific images, which are available directly via the clouds themselves, as well as on https://cloud-images.ubuntu.com.

Private clouds

Release support
Cloud images are published and supported throughout the lifecycle of an Ubuntu release. During this time images can receive all published security updates and bug fixes.
For users wanting to upgrade from one release to the next, the recommended path is to launch a new image with the desired release and then migrate any workload or data to the new image.
Some cloud image customisation must be applied during image creation, which would be missing if an in-place upgrade were performed. For that reason, in-place upgrades of cloud images are not recommended.
