Digital bank statement service architecture on AWS orchestrates multi-tenant document generation with dual authorization, fee calculation, and regulatory compliance. Retail and corporate clients submit requests through mobile app and web portal, routing through API Gateway to Request Management Service, which coordinates billing rules, manual approval workflows, and integration with FlexCube core banking. Generated statements receive digital seals via Eurotrust QES, store in DMS Archive with 5-year retention, and notify clients via push/email, with full audit logging and encryption at rest/transit. This pattern demonstrates how AWS services enforce financial controls, segregate client zones, and maintain court-admissible document integrity.
