Issuer Authorization Platform Resilience Program

Anonymized engagement for a high-volume issuer authorization platform with strict latency and continuity requirements.

Kontekst

A card authorization platform operating multi-region traffic experienced rising tail latency during dependency incidents and weak isolation in custody-adjacent signing workflows.

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.

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.

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.

Måling	Før	Etter	Endring
