Autoscaling for the city’s library catalog API should react when average CPU trends upward over a monitoring window. What kind of scaling is that?
Select an answer to reveal the explanation.
Short Explanation
Watching average CPU climb over a window is like noticing the line at the counter getting longer—then opening another register. Triggered scaling reacts to that trend instead of waiting for a calendar or a human click. Metrics drive the decision; capacity follows.
Full Explanation
Triggered scaling adjusts capacity when monitored conditions such as CPU, latency, or queue depth cross thresholds or trends. Using a windowed average reduces reaction to brief spikes. This is a core Cloud+ autoscaling pattern distinct from purely scheduled or manual changes.
