List of differences between standard and cloud systems
The goal of this page is to list the differences, and organize which and how to resolve them. Here, standard refers to Debian systems installed with DebianInstaller with the default settings, following the instructions in http://www.debian.org/releases/stable/installmanual.
Eventually, we should converge on a consensus that the remaining differences, if any, do not prevent us to claim that the cloud images are genuine Debian systems (706052).
Distribution Binary images
Debian does not distribute binary images of standard systems, but distributes installation media with a binary image of DebianInstaller.
- AWS, Azure and GCE images are available on the respective public clouds.
- Distribution of a generic cloud image in the debian archive is under discussion.

Discussions are under way (independently for DebianInstaller and cloud images) to list stable backports by default (installation of backport packages will still be manual, but updates become automatic) (1)
