Vertical Scaling is making an existing server more powerful by adding CPU, RAM, or storage. Simpler than horizontal scaling but has a ceiling. Eventually you hit the biggest server available. Databases often rely on vertical scaling because distributing them is hard.

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.
