Infrastructure as code.

Terraform provisions servers and infrastructure based on yaml config files that you can do things like commit to source control and see a diff of changes to your cloud provider. It's really fun but very tied into each specific service providers' nomenclature and services, I wish it was higher level. It provides backends for all the major players but I think there is (was?) some large variation in quality.

Wonderful talk here explaining with real examples: http://www.ybrikman.com/writing/2016/03/31/infrastructure-as...
