Objective
The Reference Architectures define all infrastructure components and properties which have effect on the virtualised services design, deployment, and operations. The Reference Architecture for Virtualised Cloud Infrastructure (RA1) specifies an OpenStack based Infrastructure-as-a-Service (IaaS) cloud architecture. The Reference Architectures define all infrastructure components and properties which have effect on the virtualised services design, deployment, and operations. The RA1 The document specifies the components of an IaaS cloud platform stack: a selection of OpenStack projects, the resources, and the interfaces exposed by a conformant IaaS cloud service to the workloads.

Over the past few years, the telecom industry has been going through a massive technology revolution by embracing software defined networking and cloud architecture principles , in pursuit of the goal of achieving more flexibility, agility and operational efficiency. At a high level, the main objective of NFV (Network Function Virtualisation) is the ability to use general purpose standard COTS (Commercial off the Shelf) compute, memory and storage hardware platforms to run multiple virtualised network services (Virtualised Network Functions (- i.e. VNF ) / Cloud Native Network Functions (- i.e. CNF)). Earlier common infrastructure models built based on the previous assumption that networking applications are typically built on discrete hardware, do not offer the level of flexibility and agility needed for the support of newer networking technologies such as 5G, intelligent networks and Edge computing.
