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
