What is a Fault Tolerant Payment System?

A comprehensive approach to ensuring continuous operation, perfect transaction integrity, and simplified operations in critical banking infrastructure.

One-Line Summary

A fault-tolerant payment system gives a bank: continuous operation + perfect transaction integrity + simplified operations

10 Core Components

Active-Active Redundancy

Duplicate hardware and software components run simultaneously

Payments continue seamlessly during hardware faults with no interruption during failures.

Ensures continuous transaction processing

Stateful Instant Failover

If a component fails, another takes over with the exact same in-memory state.

No lost or duplicated transactions, eliminating the need to retry critical operations.

Guarantees transaction integrity
