This reference architecture guide provides guidance for designing and creating a greenfield Network Functions Virtualization (NFV) platform by using VMware Telco Cloud Infrastructure™ – OpenStack Edition.

This guide describes the high-level design principles and considerations when implementing an environment based on Telco Cloud Infrastructure OpenStack Edition. It also provides example scenarios to help you understand the platform capabilities.

Intended Audience

This guide is intended for telecommunications and solution architects, sales engineers, field consultants, advanced services specialists, and customers who are responsible for the virtualized network services (VNFs) and the NFV environment on which they run.
