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

Thank you

whenever they get a chance
