Requirements

Functional Requirements:

• Create a short URL for a given long URL.
• Redirect to original long url

Non-Functional Requirements:

• 100 users / sec
• latency around 1mill sec and less than 2ms upon redirection
• we will have stability using the fastapi application to route
• we would create the application in HA mode to have full availability

API Design

Define the APIs expected from the system. This is your chance to analyze and define the read and write paths so that you can come up with the high-level design...

POST /api/v1/shorten

Body : {"long_url" : "https://..." }

Response: { "short_code": "abc123", "short_url": "http://tinyurl.com/abc123" }

GET /api/v1/{short_url} Response: 301 Redirect to original long URL

High-Level Design

Describe the overall system architecture. Identify the main components needed to solve the problem end-to-end. Use the diagramming tool to create a block diagram.

Detailed Component Design

Deep dive into 2-3 key components. Explain how they work, how they scale, discuss tradeoffs, capacity, and any relevant algorithms or data structures.
