Immutable Infrastructure is instead of updating servers in place, you build entirely new ones with the changes baked in and replace the old ones. Servers are treated like cattle, not pets. No one SSHs in to fix things. This eliminates configuration drift and "works on my machine" problems.

Short for Continuous Integration/Continuous Deployment. It automates testing and deploying your code so you can ship faster with fewer bugs.
The practice of automatically building and testing code every time someone pushes changes. Catches problems early instead of at release time.
Automatically deploying code to production after it passes all tests. No manual "deploy" button—if tests pass, it ships.
A culture and set of practices that bridges development and operations. The goal is faster, more reliable releases through automation and collaboration.
Managing servers, databases, and networks through config files instead of clicking around dashboards. Version controlled, repeatable, and way less error-prone.
