infrastructure
\A company needs 128 servers (each one containing 8 cores) and 524 TB storage to deliver a temporary service to its customers. The company should choose between two different approaches:
1- Use of Amazon cloud: where S3 costs 0.12$ per GB-month, and EC2 costs 0.1$ per core-hour. 2- Buying the whole hardware: which will cost 1,555,000$. Moreover, an administrator will be needed to manage the infrastructure and repair the hardware, who should be payed 7,500$ per month. It is assumed that in the first three years, no additional costs will be required (e.g., for replacing the hardware) The question is, how many months could the maximum duration of the service in question, so that using Amazon becomes cheaper than buying the hardware?
