Architecture Analysis

Financial infrastructure architecture determines where instructions enter a system, how transaction states change, which records carry authority and where responsibility moves between institutions, vendors and operating teams. DELCOS Architecture Analysis examines recurring design patterns across payment systems, settlement, ledgers, reconciliation, Banking-as-a-Service and compliance operations. The analysis connects interfaces and data flows with control boundaries, exception paths and dependencies that shape operating outcomes. Each article starts with a bounded architecture question and traces components through their functional relationships. It shows how integration choices allocate authority, evidence and recovery work across the operating chain. Articles may connect several domains when a transaction crosses payment processing, financial recording and compliance decisioning. Permanent knowledge on payment infrastructure and compliance systems defines the individual mechanisms. This collection synthesizes the patterns that emerge across them.
