             The Role of a Mediation Element in NFV DevOps
                draft-sonata-nfvrg-devops-gatekeeper-03

Abstract

   This document describes how a mediation element (a "gatekeeper") can
   be applied to support DevOps practices in the provisioning of network
   services based on Network Function Virtualisation (NFV).

Internet-Draft         A Gatekeeper for NFV DevOps            March 2017

1.  Introduction

   The DevOps model is already an established concept in IT industry
   reducing time to market by close collaboration between service
   developers and service operators.  The switch to virtualisation
   technologies in the network and its potential for quicker time-to-
   market deployment requires the application of agile development
   cycles supporting a DevOps approach.  This kind of approach will
   overcome key inhibitors that network operators face when deploying
   NFV, such as lack of legacy compatibility, resource orchestration,
   automation and multi-vendor interoperability, hence facilitating the
   transition to a software-driven network.  The adoption of the DevOps
   model for network services will contribute to interaction between
   development, testing, and operation of network functionalities and
   network services.  Both the function/service description formats as
   well as the infrastructure resource descriptions will be able to
   express and use legacy cases, e.g., the case of a non-virtual network
