Cloud Data Center Deployment Trends
 Continue even after NSA
 Balance shifted towards Private vs.
Public Cloud
 Data localized for Public
 Hybrid Cloud: Per Service/Application
allocation on Public/Private
 Converged Architecture
 Open
 OpenStack for IaaS getting clear

Overlay Virtual Network
 SDN as key for Cloud/Network virtualization
integration
 VxLAN becomes the first choice for Overlay
model
 OpenStack/Neutron plus SDN/VxLAN as the
preferred model
 NSX support required for VMware popularity
 The number of vswitch rapidly increase,
vRouter/vFw/VLB start to be applied
 Interoperability is still a concern
