Design a scalable URL shortening service like TinyURL or bit.ly.
The service should have the following requirements:
Functional Requirements:
Given a long URL, generate a unique short URL.
Given a short URL, redirect to the original long URL.
Non-Functional Requirements:
The system should be highly available.
Shortened URLs should not expire.
The service should be able to handle high read and write throughput (scale to millions of users).

Follow-Up Questions:
-How would you design the database schema?
-How would you ensure the uniqueness of the short URLs?
-How would you handle concurrency issues?
-How would you scale the system to handle high traffic?
-How would you handle analytics and monitoring?
•
What trade-offs did you consider in your design, and why did you choose this particular approach?
•
Excellent work on the system design exercise!
