As the developers’ choice of operating systems, Ubuntu provides numerous avenues for creating new software. Developers can pursue traditional debian package development, build universal and sandboxed Snap applications or even create Juju Charms for container orchestration.
Snaps Applications
Snaps are application packages for desktop, cloud and IoT that are easy to install, secure, cross‐platform and dependency‐free. Snaps are discoverable and installable from the Snap Store, the app store for Linux with an audience of millions.

Debian Packages
The majority of source packages in Ubuntu are copied unmodified from Debian, therefore the best route for getting packages into Ubuntu is through Debian. Not only will this help ensure your application is available to Ubuntu users, but to those using Debian and the many Ubuntu flavors, remixes and derivatives.

Juju Charms
Juju charms are deployment and service orchestration scripts that enable people to deploy services onto Ubuntu clouds on EC2, HP Cloud, and OpenStack (among others). Since Juju charms can be written in any language, it’s a good way for the devops experts to share deployment and management scripts with the community. Developers can share their charms on Charmhub, a repository of ready-to-use charms.
