Sending synchronous responses to requests from frontend applications

A system includes a first node and a second node. The first node includes a first memory storing executable instructions for configuring the first node to receive a service request from a frontend application. The first node identifies a timeout required for processing the service request and sends the service request to a backend application for processing. The second node includes a second memory storing executable instructions for configuring the second node to monitor for a response regarding results of processing of the service request. In response to the timeout for the service request elapsing before receiving a backend application response to the service request, the second node sends a response informing the frontend application from which the service request was received that the backend application has not responded to the service request.
