Design a URL shortener like bit.ly

Difficulty: easy

Requirements

• Users create a short link for a long URL
• Opening a short link redirects in a few milliseconds; reads outnumber writes 100 to 1
• The service keeps working when one server fails

Draw the architecture from components such as load balancers, caches, queues and databases, then check it against the requirements.
