This deployment diagram depicts the infrastructure of an ATM system, outlining devices, software artifacts, and communication flows. The ATM Device contains the UI, card reader, cash dispenser, and receipt printer, sending transaction data to the ATM Local Controller, which hosts the session manager, transaction cache, and diagnostics. The Local Security Gateway ensures encryption, fraud detection, and PIN block generation.
Data passes through the Network Security Infrastructure with firewall, VPN, and intrusion detection before reaching the Bank Data Center. The data center includes the primary and backup bank application servers, authentication cluster, and database cluster for processing, verification, and record storage.
