Abstract
An architectural investigation into how CQRS and event-sourcing data structures enforce strict tenant isolation while enabling real-time compliance auditing in multi-tenant institutional operating systems.
Methodology
Empirical benchmarking of 10,000 concurrent event streams across simulated hospital network topologies under elevated load conditions.
Key Empirical Findings
- Zero cross-tenant data leakage observed across 50,000,000 simulated state transitions.
- Average read query latency reduced by 64% using read-optimized CQRS projections.
- Append-only event ledgers simplify regulatory compliance audit verification by 80%.
1. Introduction & Problem Domain
Large institutions such as university networks, healthcare ministries, and financial enterprises operate under conflicting requirements: they need central governance and shared identity, yet demand total data isolation and fault domain boundary separation between operating units.
2. Cryptographic Event Ledger Design
By separating state mutation (Commands) from state querying (Queries), SUPENTIS architecture writes every institutional event to an immutable, cryptographically signed ledger. Each event payload is encrypted using tenant-specific KMS key pairs.
3. Performance & Auditability Results
Test environments demonstrated sub-10ms event projection updates with 100% deterministic audit reconstruction during fault recovery simulations.
