Core platform layer
Define where trading platform components live and which systems are allowed to communicate with them.
Access and network topology
Separate client access, administrative access and integration traffic. Document firewall rules, private links and monitoring points.
Redundancy and recovery
Production plans should include backup strategy, recovery procedures and tested operational ownership.
Observability
Monitoring, logs and incident procedures should exist for critical broker components and integration paths.
Change control
Platform changes, plugin updates and integration releases should be tested and documented before reaching production.
