-One of the defining characteristics of software engineering is that a single person or small team
-can create, deploy, and operate a nontrivial application or entire system of software.
-However, depending on the structure of our team, organization, or education,
-we may rarely learn in any depth - if at all - how to deploy and operate our software in production.

-These resources seek to bridge this gap and provide a path to understanding fundamental concepts
-behind modern software infrastructure and operations, while defining automated, repeatable processes
-which enable us to ship software, then ship it again and again and again.
