Problem

An ad-tech company has three storage problems on one platform: a bidding service writing 80,000 transactions per second with 12ms primary-key lookups, a reporting team scanning 365 days of bid_facts (2 PB raw) for an advertiser dashboard, and a data science team training on the full raw bid history. Apply the entire L3 storage tier (the three foundational shapes plus the four optimization levers) so each workload runs on storage matched to its access pattern.
