Issuer Authorization Platform Resilience Program
Anonymized engagement for a high-volume issuer authorization platform with strict latency and continuity requirements.
01
Kontekst
A card authorization platform operating multi-region traffic experienced rising tail latency during dependency incidents and weak isolation in custody-adjacent signing workflows.
02
Teknisk risiko
- Authorization throughput degraded under partial dependency failure, with unstable p95 latency.
- Signing service fault boundaries were insufficiently isolated, raising compromise blast radius.
- Incident recovery lacked deterministic rollback controls across critical service groups.
03
Intervensjon
- Re-architected request routing and fallback control to preserve throughput under dependency instability.
- Introduced stronger signing-boundary segregation and key lifecycle guardrails.
- Implemented deterministic rollback gates with release-level verification checks.
04
Målt resultat
- Service continuity improved during degraded-state operation.
- Critical signing paths retained control under incident pressure.
- Operational teams reduced restoration time for high-severity incidents.
