Task 4.1: Design cost-optimized storage
QuestionWatch the method
Predict first. Then watch short phrases—not full sentences—drive the decision.
Scenario
Vanth Insurance holds 80 TB of closed claim files that the business has not opened in two years and expects to open perhaps twice more before they age out.
Compliance requires the files to stay retrievable for seven years from closure, after which they should disappear on their own.
The auditor who does ask gives two weeks of notice, so a retrieval that takes hours rather than milliseconds is fine; finance simply wants the smallest possible storage bill.
Question
Which design holds the files for the full seven years at the lowest storage cost?
