1. A method comprising:
identifying, by a device, a plurality of paths between a pair of network addresses, wherein one of the pair of network addresses is associated with an online application;
obtaining, by the device, telemetry data from the plurality of paths for the online application;
computing, by the device and based on the telemetry data, fate sharing metrics for the plurality of paths, wherein the fate sharing metrics indicate how likely the plurality of paths are to provide acceptable or unacceptable application experience during any given time period; and
controlling, by the device, routing of application traffic for the online application between the pair of network addresses, based on the fate sharing metrics for the plurality of paths.
