API Calls from Production server to Failover Server

Benzema

Hey would like to know if we have running flows or any calls API calls being made to Decisions Prod instance and Production instance goes down will the flows will end in an exception or Failover Server will handle those flows/request or something else?

Hey! That's a interesting question. So there can be two scenarios here.

1. Before reaching Decisions (Load Balancer stage): If the request is still at the Load Balancer and hasn't reached the Decisions server, it will be redirected to a Failover Server.
2. After reaching Decisions (Decisions Server stage): If the request has already been passed from the Load Balancer to the Decisions server and the server goes down, the request might not be updated. This scenario implies a gap in fault tolerance once the request has left the Load Balancer, potentially leading to data inconsistencies or unprocessed requests.

Note: Failover Servers need to be enabled manually, and they should never receive any requests directly unless the customer reconfigures the server and the network routing.
