Automatic transaction processing failover

Transaction authorization systems may include a transaction processor and an authorization server system. The transaction processor obtains transaction requests authorizations for those requests from the authorization server system. The transaction processor may require an authorization be provided within a threshold time; otherwise, the transaction may be processed without authorization. The authorization server system may be hosted using one or more nodes in a distributed system. Degradation of the performance of the distributed system may cause the performance of the authorization server system to fall below the required performance threshold and transactions may not be authorized before automatic processing. Transaction authorization systems may monitor the health of the individual nodes and/or the distributed system and automatically adjust the routing of authorizations based on current and/or future performance degradation. The transaction authorization system may also allocate additional resources and/or reroute authorizations to a separate distributed system to avoid performance degradations.
