2. EvenwithinsometrueSD-WANsolutions thereisarealgapinfeatureavailabilitybetweenmarketingslidewareandexperienceinthefield– enterprisesoftenonlyfind thisoutduring ProofofConcepts

3. Enterprisesshouldpayattentiontosolutionarchitecture– don’tbefeatureled.Focusonhowthesolution wouldapplytoyourspecificapplicationmixandtrafficengineering requirements
