Problem Statement
==================
+Providing carrier grade Service Assurance is critical in the network
+transformation to a software defined and virtualized network (NFV).
+Medium-/large-scale cloud environments account for between hundreds and
+hundreds of thousands of infrastructure systems. It is vital to monitor
+systems for malfunctions that could lead to users application service
+disruption and promptly react to these fault events to facilitate improving
+overall system performance. As the size of infrastructure and virtual resources
+grow, so does the effort of monitoring back-ends. SFQM aims to expose as much
+useful information as possible off the platform so that faults and errors in
+the NFVI can be detected promptly and reported to the appropriate fault
+management entity.
