Order management system with recovery capabilities

A method comprising:

• implementing first management hardware including first primary hardware and first backup hardware, the first primary hardware including an order flow manager to route orders and a primary order manager to process first orders, the first management hardware disposed at a first geographical location;
• implementing second management hardware including second primary hardware and second backup hardware, the second primary hardware including an order flow manager to route orders and a primary order manager to process second orders, the second management hardware disposed at a second geographical location;
• via a synchronizer, synchronizing storage of data between the first management hardware and the second management hardware;
• and
• wherein the first backup hardware is substantially a replica of the second primary hardware, and the second backup hardware is substantially a replica of the first primary hardware, the method further comprising:
• during first conditions, via the order flow manager of the first primary hardware:
• i) forwarding the first orders to the primary order manager of the first primary hardware for execution, and ii) forwarding the second orders to the primary order manager of the second primary hardware for execution, wherein the order flow manager of the second primary hardware is inactive during the first conditions;
• and
• during second conditions, via the order flow manager of the second primary hardware:
• i) forwarding the first orders to an auxiliary order manager of the second backup hardware for execution, and ii) forwarding the second orders to the primary order manager of the second primary hardware for execution, wherein the order flow manager of the first primary hardware is inactive during the second conditions.
