An order book management system built with immutable audit logs and high availability is typically an exchange-grade OMS/EMS or matching-engine platform with append-only event sourcing and HA clustering.

If you’re asking about a specific product category, the key capabilities to look for are:

  • Immutable audit logs: append-only transaction/event logs, tamper-evident storage
  • High availability: active-active or active-passive clustering, failover, redundancy
  • Exchange operations support: real-time order matching, surveillance, reconciliation, and disaster recovery

If you want, I can also give you:

  1. a list of vendors/products that fit this description, or
  2. a reference architecture for building such a system.
