URL shortener
Design a service that creates short links and redirects 12,000 visitors per second, with a monthly budget of 2,500 dollars.
Redirects outnumber new links a hundred to one, and a small set of viral links gets most of the clicks. At 15:00 an instance will fail.
What your design must achieve
- Availability ≥ 99.9 %
- Latency p99 < 100 ms
- Infrastructure cost per month < 2,500 $
