Benefits •  Improved experiences for your

customers •  Faster fulfillment times, newer

methods to service ordering •  Deploy new applications and

network services at web speed •  Accelerate your time to revenue •  Cut operational costs significantly

Benefits of NFV approach

NFVI


•  Many entry points •  Replace PNF with VNF •  Use an Orchestration solution to

provision your PNFs •  Implement a NFVI and manually deploy

VNFs •  Build an ETSI like reference architecture

(NFVI, VIM, VNFM, Orchestrator) -- OR --

•  Adopt a pre-packaged ETSI like evolved platform w/ •  + pre-packaged solutions + easy to

use Portal

•  Better customer experience •  Customizable portal

•  Faster time to market •  Significantly reduces in-house integration

time for the base platform

•  Pre-packaged solutions / functions reduces ROI period

•  Focus on business services, rather than underlying stack

Examples of pre-packaged services •  Cloud VPN - Highly secure business

connectivity and routing (VPN) for site-to-site, and remote access

•  Cloud MPLS - Security services delivered over your existing MPLS VPN connectivity

•  Cloud iWAN services – Secure connectivity over flexible transport options, using hybrid WAN (MPLS or Internet) with Dynamic Multi-point VPN overlay

Benefits of adopting an Evolved Platform


Service Fulfillment in the virtual world

•  Automated Business process & rules driven

•  Service provisioning will be through orchestration engines

•  Opportunities to customize and/or create new services

Adoption Challenges •  Solution deployment

(upgrade, new services, etc.) are lot more (near) real-time

•  Integration with OSS/BSS is lot more dynamic

•  Challenges various aspects of current Solution development and Operational processes

DevOps Transformation

“Highly effective collaboration between software developers and operations people to produce relevant, working systems”

DevOps principles span several areas: Ø Culture Ø Automation Ø  Lean Methods Ø Metrics


Transforming Operations into a strategic weapon

Source: DTO solutions


DevOps- Key Principles

Ø  Ensuring focus on Business service Ø  Breaking down barriers between teams Ø  New Roles & Shared Responsibilities

Ø  Improving & Automating Handoffs between Silos Ø  Removing Constraints & Bottlenecks Ø  Creating Feedback Loops at every stage

Ø  Infra as a Code, Release Automation- CI/CD Ø  Production Like Test & Staging Environments Ø  Monitoring, Metrics & Security

Key Takeaways

Ø  NFV/SDN - a major shift in telecom network architecture Phased Migration, Hybrid environments

Ø  NFV/SDN architecture will impact most operations functions Ø  NFV/SDN is disruptive and SP’s require transformation at every level

Employee skillsets, process reengineering and automation, and new OSS capabilities Ø  A DevOps based model needs to be introduced for agility & scale
