What is Auto-scaling?
Automatically adding or removing servers based on current demand.
Why It Matters
Auto-scaling ensures your app handles traffic spikes without manual intervention and saves money during quiet periods.
Real-World Example
During a product launch, auto-scaling adds more servers to handle the rush, then removes them when traffic drops.
“Understanding terms like Auto-scaling matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
