FaultRay's a prototype simulating cascade failures via labeled transition systems, no production contact required.

How does FaultRay differ from chaos engineering tools?

Chaos tools inject real faults in live systems; FaultRay models mathematically on graphs, proving properties upfront.

Can FaultRay predict my system's max availability?

Yes, via five-layer min operator, factoring deps, SLAs, and irreducible limits.

FaultRay: Math Over Chaos for Cascade Failures That Won't Kill Your Prod

Chaos engineering promised resilience testing, but prod poking terrifies regulators. FaultRay flips the script with formal math on failure propagation, no systems harmed.

⚡ Key Takeaways

FaultRay models cascades without touching production, ideal for DORA compliance. 𝕏
Formal LTS proofs monotonicity, causality, and termination—beyond empirical tests. 𝕏
Availability ceiling uses min across layers, exposing external SLA hard caps. 𝕏
