using serverless framework and aws lambda to implement url shortener
- URL shortening: given a long URL => return a much shorter URL
- URL redirecting: given a shorter URL => redirect to the original URL
- High availability, scalability, and fault tolerance considerations
- Write operation: 100 million URLs are generated per day.
- Write operation per second: 100 million / 24 /3600 = 1160
- Read operation: Assuming ratio of read operation to write operation is 10:1, read operation per second: 1160 * 10 = 11,600
- Assuming the URL shortener service will run for 10 years, this means we must support 100 million * 365= 36.5 billion records.
- Assume average URL length is 100.
- Storage requirement over 10 years: 365 billion 100 bytes 10 years = 365 TB
