What is Autoscaler?
A system that automatically adjusts the number of running instances of your application based on demand.
Why It Matters
Autoscalers ensure you have enough capacity during peaks without paying for idle resources during quiet periods.
Real-World Example
Scaling from 2 to 20 instances during a flash sale, then back to 2 when traffic returns to normal.
“Understanding terms like Autoscaler 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.”
