   Conclusion
   The programmability and control introduced by the
   NaaS with the use of SDN by moving the control plane
   in software not only solves the current problems but is
   beneficial to
   • VM mobility
   • InterCloud – Hybrid cloud
   • Differentiated Network Services
   • Network Agility
   What Next ?
   • Network Aware VM Placement
   • *-aaS based on NaaS
   • Making it Open Source
   NaaS component Services
   • Network Access Service
   • Virtual Connectivity Service
   • Virtual Topology Service
   • Virtual Node Service
   Motivation
   • Management
   • 1,00,000 servers, each hosting 32 VMs translates to more then
   3 million IP and Mac addresses
   • With 25 port switches, more then 8000 switches in access tier
   • And we have aggregation tier, core tier, disaster recovery….
   • Extensibility
   • Application Migration
   • Addressing Issues
   • Performance
   • Learning what is already known
   • Vendor Lock-in
   • Fair Share Network Assumption
   • Everyone is considered equal when it comes to Network
