Problem context and objectives
Lead systems engineer · The Production Readiness Gate
A new inventory service passes functional tests and is ready for launch review. Pressure-test it across reliability, security, performance, operations, cost, and safe delivery.
The design must survive requests 100K/s peak and availability 99.95%. Every box must earn its place by satisfying a requirement or containing a failure.
How you win
- 1Trace one user action from request to durable outcome
- 2Connect every component to a stated requirement
- 3Explain the losing tradeoff, not only the chosen technology
Rules and pressure
- requests: 100K/s peak
- availability: 99.95%
- Graceful dependency failure
- Least-privilege access

The Production Readiness Gate: request to outcome
Game services sends “scoped request” to Authenticated API. Reliability includes redundancy, failure isolation, backpressure, retry safety, graceful degradation, tested recovery, and explicit RTO and RPO targets.
A new inventory service passes functional tests and is ready for launch review. Pressure-test it across reliability, security, performance, operations, cost, and safe delivery. Follow one real user action through the complete architecture; a component is useful only when you can explain the request, state, or failure it handles.
