Network Virtualization with Overlays
• NV is an approach which
provides a flexible virtual
network atop an existing
physical network infrastructure
using an overlay technology
• NV helps automate network
configuration while
provisioning
applications/tenants
• NV provides a scalable, multitenant virtual network via
overlay technology

The Road to Nirvana
Hardware Underlay
• Majority of
infrastructure not
SDN capable
• Move from legacy 3
tier to Ethernet Fabric
in DC
Orchestration
• First step in the
journey of SDN for
many
• Software skills are
extremely critical for
success
Programmability
Policy Driven
• A true paradigm shift
• Use case scenarios
in how networking is
will vary by each
implemented
environment
• Silos broken down to
• Apps emerging that
support a horizontal
address specific needs
focus
