Elasticity
ELI5 — The Vibe Check
Elasticity is the cloud's ability to stretch when you need more resources and shrink when you don't — automatically and instantly. It's the superpower that makes cloud computing worth it. Your app handles Black Friday like a beast and then quietly scales back to save money at 3am Tuesday.
Real Talk
Cloud elasticity is the ability to dynamically provision and de-provision computing resources in near-real-time to match current demand. Unlike scalability (which is about maximum capacity), elasticity emphasizes rapid, automatic adjustment. It's a core cloud characteristic that enables cost efficiency and performance optimization simultaneously.

Horizontal scaling means adding MORE servers to handle load instead of making your server bigger. Got too much traffic?
Serverless
Serverless doesn't mean there are no servers — it means YOU don't have to think about servers. Someone else manages them, scales them, and patches them.
Vertical Scaling
Vertical scaling means making your existing server bigger — more CPU, more RAM, more disk.
