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
Data Center Resources
OpenStack API, AWS

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
