You only need to know one tool !!!
Berlin DevOps Meetup - May 2015
One tool to rule them all
Developers focus on development
Ops and Devs have a common "language" to speak
Reusability of tools between developers (even vim configuration)
Not needed to jump all into Nix. Gradual migration. Nixify only when it brings the value.
Reproducible environments without any virtualization/containers
