According to some embodiments, a system comprises a plurality of data centers communicatively coupled by a network. The data centers include an assigned data center and a second data center. The assigned data center receives a request for a session, determines the session passes authentication, and communicates session information to the second data center indicating the session passes authentication. The assigned data center also receives a first message comprising a first portion of transaction information and communicates synchronization data for replicating the first portion of transaction information at the second data center. The second data center receives a second message comprising a second portion of transaction information. The system facilitates a financial transaction in real-time based on the first portion and the second portion of transaction information.
