Transformation challenges

• Adjust network operations for the virtualized network: OSS/NFV MANO/SDN controller co-existence– Service orchestration vs multi-domain service

orchestration • Enable rapid service lifecycle management

automation – ‘DevOps’– Supporting network operations with DIY tools

• Reduce time and cost associated with service change– Microservices-based deployment

Microservice architecture for speed and flexibility

Microservices is a software architecture style in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs. These services are small, highly decoupled and focus on doing a small task,facilitating a modular approach to system-buildingSource: Wikipedia

• Becoming the standard for cloud native app development• Scalability and resilience properties • Can be deployed using containers• Components easily changed/replaced for rapid feature

innovation• Supports continuous integration• ‘Two pizza’ DevOps team rule• ‘SOA done right’

TMF Future Mode of Operation

• Microservice architecture, domain-driven design (DDD) and composability provide inspiration for the TMF’s future approach to managing the cloudified network

• TMF Future Mode of Operation (FMO) approach proposes that the network will be composed from “well-behaved” functions, each integrating with Operations, Applications, Security and Execution environments

Network IT power shift away from professional services

“If you go to the IT department to get things done, it’s astronomically expensive. The OSS people have to write requirements, then code and test, but they don’t understand the network. Give me the tools and I can rapidly

prototype what I want in a day. What I want from the OSS guys is an abstract view of the service and I’ll decide how to implement it.”

Service Ordering and DeliveryService Planning

Weeks to Months

Network architect defines and programs physical and virtual resources using template to create new service offering

Customer orders new service via operator’s web portal

Minutes to Hours

Orchestration platform and/or controller instantiates and automatically configures the end-to-end service

Service is activated in real-time and available to the customer

Legacy OSS Limiting SDN and NFV Benefits

Legacy OSS is hard coded, no self-service

Pro-serv required for even simple changes

Time-to-market affected by rigid processes

Significant cost to update OSS

Slow OSS update with the same vendors

• BPMN is the global standard for process modeling

• End-to-end process flow

• Technical and business users

• Business/IT alignment

• Streamlines integration of SDN and NFV-based services with the OSS/BSS

• Simplified creation, integration, and operation

• Accelerate new product introduction

• Enables operational agility and improved time-to-market • DevOps style workflows and processes break the vendor lock-in cycle
