# Architecture

The architecture diagram depicts a robust Certificate Authority (CA) infrastructure. In this setup, a secure firewall intermediates the data flow between the Internet and two distinct data centers: the Production center, featuring multiple signing servers and associated hardware security modules (HSMs), and the Disaster Recovery (DR) center, which ensures continuous service availability and data integrity.
