  • Aplication Policy Infrastructure Controller ( APIC ).
    • Cisco recommends a minimum of three APIC servers.
  • Policy Model ( “What talks to what and how” ).

How it works

Reality of SDN

  • New, minimizes data center capital Investment
  • Cisco ACI, Vmware NSX platforms locked to vendor
    • Opendaylight example of Vandor inspecific Solutions
