Abstract

Implementations described herein relate to systems, methods and computer-readable media to provide high availability computer architectures for performing real-time authorization of transactions. In some implementations, the method includes receiving, at two or more groups of authorization control pods, transaction information about the transaction from a payment network, wherein each authorization control pod includes a processing service, a database service, and a policy agent; processing, at a corresponding policy agent of a single authorization control pod of the two or more groups of the authorization control pods, the transaction information by comparing one or more transaction attributes in the transaction information combined with contextual and historic data against one or more policies stored in the database service; and based on the comparison, transmitting one of an approval or a rejection of the transaction to the payment network.
