Containerization
Definition
The overarching process of packaging an application along with its required libraries, frameworks, and configuration files together so that it can be run in various computing environments consistently.
Explain Like I'm New
The act of taking your messy, complicated software project and locking it inside a standardized Docker box so you can ship it anywhere.
