A FailoverService creates a new hostname to which services can send requests. Requests will be routed based on a list of backing traffic targets ordered by decreasing priority. When outlier detection detects that a traffic target in the list is in an unhealthy state, requests sent to the FailoverService will be routed to the next healthy traffic target in the list. For each traffic target referenced in the FailoverService's BackingServices list, outlier detection must be configured using a TrafficPolicy.
Currently this feature only supports Services backed by Istio.
