Keys to NFV Success Lessons learned from large datacenter migrations to virtualized infrastructure

HOW TO ADDRESS YOUR PRESSING STRATEGIC EFFORTS?

• Start with architecture planning

• Prioritize phasing order

• Transform operational support

• Streamline vendor portfolio


The 4 pillars of NFV

NFV

Virtualization

• Virtual network functions

(VNFs/VMs)

• Significant multi-tenancy

• High performance

• Comprehensive hypervisor

support

Abstraction

• Service and network

abstraction

• Configuration templates

• On demand resourcing

Programmability

• Data, control &

management planes

• Open and production-

deployed APIs

• Developer-friendly

RESTful APIs

• Large existing developer

community & ecosystem

Orchestration

• Unified multi-vendor,

multi-service ecosystem

• Open and standards

based multivendor

integration

• Policy-driven flows and

steering


NFV Deployment Phases – F5 perspective Building an application delivery network that is zero-touch and fully programmable
