Architecture layers
A practical model separates client access, platform core, pricing, execution connectivity, operational integrations and observability. Separation clarifies failure domains and scaling decisions.
Access-layer design
Access services can be distributed closer to user populations while the core remains positioned around critical data and execution dependencies.
Bridge and liquidity path
Map the full order route from platform to bridge or gateway and onward to liquidity. Document failover behavior and symbol mapping.
Disaster recovery
Recovery architecture needs explicit objectives for data, configuration, service restoration and communication. A backup without a tested restore process is incomplete.
Architecture layers to document explicitly
Client access
Regional access placement, DNS strategy and network paths should match the user geography.
Trading core
Keep the central platform role clear and avoid mixing unrelated high-variance workloads without reason.
Data and execution
Map every market-data and liquidity dependency, including failover paths and symbol-routing rules.
Recovery plane
Backups, standby capacity, configuration copies and runbooks should be part of the architecture diagram.
