Introduction

This session shows the benefits of NSO adopting the DevOps concepts andstrategies in order to reduce Capex and Opex to evolve the inside culture of eitherservice providers or enterprises to make sure the future deliveries with qualitycontrol, continuous integration and velocity of the current market demands. Whichmeans the right time to market to launch new applications and services.

Assumptions

Cisco starts with the assumption that orchestration should be an enabler ofmultivendor NFV, not an obstacle. We provide an API-first, “bottom-up” solutiondesigned to simplify NFV for developers and facilitate DevOps ways of working.With the Cisco NFVO platform, customers can take advantage of opentechnologies and emerging standards more quickly and easily adapt them to localrequirements. They can use rich network abstractions that are simple to consumeand straightforward to integrate into surrounding systems.

11PSOSPM-3422


DevOps Culture

There are 3 main challenges that we face to embrace a DevOps and NSOAutomation culture

1. Awareness: All sort of customers and the software communities at all levelsneed to know the Cisco NSO, Automation Software and DevOps portfolio

2. Acceptance

3. Adoption

The current landscape of ecosystems

for Customers require new approaches.

DevOps towards NSO and Cisco Digital

Network Architecture is the core

conversation with Service Provides and

Enterprise Customers.



14PSOSPM-3422

Once an organization acquires

any automation and orchestration services

therefore experience the capabilities and

opportunities, then they are keen and willing

to explore more about Network Services

Orchestration and Automation embedding a

DevOps culture in the organization.



Cisco NSO as the Orchestration product and service solution to homologate theexisting network infrastructure.

Cisco NSO as the platform for new deployments, software upgrades, migrationservices with standard compliance for multivendor networks.

Cisco NSO as the platform to modernize the existing organizational culture forservice providers and enterprise, and let the customers know that Cisco NSO isbuilt with Yang Modeling, DevOps concepts, capabilities and compatibilities tomake sure compliance, agility and quality in the orchestrated deliveries.

NSO as platform for seamless deliveries in multivendor platforms with complianceand standards assurance

DevOps and Orchestration practices are enablers of innovation, speed and qualitydemands expected by the current landscape

DevOps depends on automation, therefore to gain agility it is needed a NetworkOrchestration Service platform

One of the biggest challenges for Service Providers is to meet the customerexpectations, although in parallel they need a transformation either ininfrastructure, services and also adopting new culture approaches such as NSOand DevOps

17PSOSPM-3422



In order to outpaced the competitors, SPs need to embrace agile methodologiessuch as DevOps with Open Source ecosystems with vendor endorsement andcompliance.

NSO Design, Planning, Implementation is based on work flows which for DevOpsis one of the main objectives, since it is based on continuous integration,continuous delivery and continuous deploy

NSO Implementations are cross-functional as DevOps is which having the sameteams and process agile the continuous integration and delivery which reducesilos and increase time to market.

PSOSPM-3422 35


• Provides a framework for the system engineer to design and deploy a VNF usecase topology

• VNF can be simple (single VM) or complex (multiple VMs in a service chain).

• Specific deployment instantiation is based on designed blueprint (VNFD/NSD).

• VNF-Instantiation: The NFVO package will instruct the VNFM (ESC) to deploy theVM(s) with a Day0 config file, assign IP addressing, and attach the VMs to pre-created networks and (if applicable) create ephemeral networks as needed(usually internally connecting to VMs in a service chain).

• VNFM will provide lifecycle functions, including fault detection, scaling, notifications
