Beginner Topic 6 of 51 Distributed Systems & Cloud

Latency vs Throughput

Time per request versus requests per time.

How it works

Latency is time for one request; throughput is requests per second. Little's law: concurrency = throughput × latency. Tail latency (p99) often matters most.

Where it is used

Performance tuning.

Common pitfall

Optimizing average latency hides slow outliers.

Where it fits in the course

Latency vs Throughput is topic 6 of 51 in Distributed Systems & Cloud, rated Beginner. It follows Vertical vs Horizontal Scaling. The next topic is Availability and Reliability.
