Dependency management, deployment tooling, secret management, rollbacks, NixOS modules, systemd integration, unit and NixOS VM tests all come together thanks to the Nix language to help us serenely deploy and maintain self hosted applications.

This talk shows how standardizing NixOS options for modules achieving the same goal (SSO, backup, etc.) can move Nix one step forward to be an industry leader in the Server Management tooling space.
