Case study — 2026
A conceptual gateway that synchronizes several applications without exposing their data or weakening operations.
Key decisions
The context, trade-offs and technical choices that shaped the outcome.
Passerelle orchestrates exchanges between business applications with different contracts and operating rhythms. It transforms, validates and distributes data without creating direct dependencies between systems.
API contracts are versioned, messages are idempotent and retries are automatic. An isolated failure does not block the entire flow.
Service authentication, encryption, network filtering and audit logs limit exposure. Metrics and alerts make it possible to follow each exchange to its destination.
