If you like Nix than probably try GNU Guix [1] and if possible use Guix System on server side. This is one of the most modern development in operating systems.
In the modern security conscious world where most companies run their workloads on virtual machines controlled by other companies, it's imperative that applications are deployed on such predictable, secure and reproducible operating systems.
Guix supports transactional upgrades and roll-backs, unprivileged package management, and more. When used as a standalone distribution, Guix supports declarative system configuration for transparent and reproducible operating systems.
I still think Amazon, Google and Azure will take a decade or two to build and offer something like this to it's customers. Indeed Google's Fuschia is trying to do the same, but I feel it's at least a decade away.
It has one of the best wonderful documentation [2] to get started and explore with all the details.
