Legacy and novel network services are expected to be migrated and designedto be deployed in fully virtualized environments which lead to novel network architecturesthat challenge legacy fault management systems and resilience characterization. Indeed, thecoordination among the different software components for, e.g., orchestration, switching, andvirtual machine and container management creates different monitoring points, besides novelsources of faults and bugs. In this thesis, we propose a network automation framework thatdetects anomalies and characterizes the resiliency state of a virtualized network service.
