It is a view that shows 8 of the model's 11 components and 8 of its 11 connections. Cloud region eu-central-1: Invoices, Private network. Private network (in Cloud region eu-central-1): Shop API, Order events, Order worker, Data zone. Data zone (in Private network): Orders. Main path: Customer → Web shop → Shop API → Order events → Order worker → Payment provider. Most connected: Order worker (4 connections). Nothing leads into Customer. Nothing leads out of Orders, Invoices and Payment provider. Bottleneck: Shop API; without it the diagram falls apart. Customer (person): connects to Web shop (browses). Web shop (frontend): connects to Shop API (calls, via HTTPS/JSON). Shop API (service): connects to Orders (reads, writes, via SQL/TLS) and Order events (publishes, via AMQP). Order events (queue): connects to Order worker (delivers). Order worker (service): connects to Payment provider (charges, via HTTPS), Invoices (stores PDF, via S3 API) and Orders (updates, via SQL/TLS). Orders (database): no outgoing connection. Invoices (storage): no outgoing connection. Payment provider (external system): no outgoing connection.</desc><style>.chartlet-root{--chartlet-text:#172033;--chartlet-muted:#344054;--chartlet-grid:#d9dee8;--chartlet-zero:#667085;--chartlet-accent:#2563eb;--chartlet-background:#fff;--chartlet-color-1:#2563eb;--chartlet-color-2:#c2410c;--chartlet-color-3:#475569;--chartlet-color-4:#111827;max-width:100%;height:auto;font-family:Inter,ui-sans-serif,system-ui,sans-serif;color:var(--chartlet-text)}#chartlet-6eb2843d93367fb7
