Advanced Topic 44 of 51 Distributed Systems & Cloud
Auto Scaling
Adjusting capacity automatically to demand.
How it works
Scaling policies add or remove instances based on metrics (CPU, queue length, requests) or schedules, with cooldowns and min/max limits.
Where it is used
Handling variable traffic.
Common pitfall
Slow scale-up misses spikes; flapping from tight thresholds.
Where it fits in the course
Auto Scaling is topic 44 of 51 in Distributed Systems & Cloud, rated Advanced. It follows Infrastructure as Code. The next topic is Rate Limiting.
