Twin Cloud Architecture

Twin cloud architecture deploys an application redundantly across two cloud regions or providers so a fleet platform stays available if one region fails, supporting disaster recovery and data residency. It is a generic IT resilience pattern, not a maritime standard; vendors apply it to vessel-performance, ERP, and tracking platforms where downtime would interrupt voyage decisions or regulatory reporting. The term is also used loosely; confirm a specific vendor’s meaning before relying on it, as some use it for an active-active setup and others for an active-passive failover.
