Data zone (in Private network): Orders. Main path: Customer → Web shop → Shop API → Order events → Order worker → Payment provider. Customer (person): connects to Web shop (browses). Web shop (frontend): connects to Content network (loads assets, via HTTPS) and Shop API (calls, via HTTPS/JSON). Shop API (service): connects to Session cache (sessions, via RESP), Sign-in (checks token, via OIDC), Orders (reads, writes, via SQL/TLS) and Order events (publishes, via AMQP). Content network (external system): no outgoing connection. Session cache (cache): no outgoing connection. Order events (queue): connects to Order worker (delivers). Sign-in (security): no outgoing connection. Order worker (service): connects to Payment provider (charges, via HTTPS), Invoices (stores PDF, via S3 API) and Orders (updates, via SQL/TLS).
