Overview
What this challenge is about.
Map the access patterns (90 percent reads from the country of origin, 10 percent cross-country via teacher reviewers). Design region routing using a metadata service backed by a globally-replicated key-value store (FoundationDB or CockroachDB). Evaluate two consistency models: strict (writes block on cross-region replication) vs eventual (with anti-entropy reconciliation). Prototype the metadata service in TypeScript with a CockroachDB cluster. Build a TCO (total cost of ownership) model covering storage, egress, and operational overhead. Deliver design doc, prototype, and cost model.
The Brief
What you'll do, and what you'll demonstrate.
Design a GDPR-compliant geo-distributed storage layer for student assignments with per-country residency and an honest cost-vs-latency tradeoff analysis.
Earning criteria — what you'll demonstrate
- Design data-residency-compliant geo-distributed storage from first principles
- Evaluate strict vs eventual consistency for a mixed access workload
- Build a TCO model that includes egress and operational overhead, not just storage
- Communicate a data-architecture decision to a non-technical legal stakeholder
