If a service fails but has redundancies in place, what typically happens?

In scenarios where a service has redundancies in place, the design aims to ensure continuity and availability. When a service fails, the system is typically configured to automatically reroute subsequent requests to operational services that can still handle user demands. This process leverages backup resources, load balancers, or failover mechanisms to ensure seamless access to the service, maintaining operational functionality for users. The redundancies in this context might include additional servers, alternate data paths, or different geographic locations that continue to operate even if one part of the service experiences an outage.

While other outcomes, such as minimal disruption, can occur, the emphasis in this particular case is on the rerouting of requests to maintain service continuity, which is a core principle behind resilient architecture and redundancy strategies in service design. This capability is crucial in minimizing the impact of failures and providing a positive user experience despite underlying issues in the system.
