•  Changing Customer Behavior, New Expectations •  Everything on demand •  New services with a press of a button

•  Rapidly Changing Business Models •  Cloud services, virtualization, programmable networks •  New eco-systems and value chains •  OTT “co-opetition”

•  Execution at the speed of software •  Agility, DevOps, NFV, SDN, new services platforms

Key Market Trends and Challenges

All of this requires successful, flexible automation… …But complexity has destroyed many automation initiatives


Barriers to Successful Automation

Growing Complexity •  Proliferating devices and service types •  Heterogeneous environments •  Legacy IT and automation can’t keep up Current Automation Complex, Rigid, Fragile •  Hardcoded logic flows and CLI templates •  Fragile programmatic adapters •  One-off solutions—not repeatable or reusable

Lack of Visibility and Granular Control •  Data quality issues •  No transactional control •  Complex rollbacks and remediation

High Fallout Ratios and Broken Configurations = Higher Costs, Slower Service Activation


What if You Could… Break the Complexity Barrier to Enable Agility

•  Full Lifecycle Automation (Create, Update, Delete) •  Model Driven to Reduce Code and Expand Features

Reconfigure Services with High Quality and Minimal Impact •  Non-Disruptive Updates of Service and Device Models •  Surgical Precision and Atomic Transaction Control

Support Real-World Multivendor Environments •  Any Use Case on Any Device •  Hybrid/Brownfield Environments •  Full Stack—Beyond Layer 2/Layer 3

Decouple Services from Infrastructure •  Physical and Virtual Networks and Service Platforms •  Minimal Dependencies on Networking Technologies •  Minimal Dependencies on OSS Environments


Agile •  Strict YANG Models for

Services & Devices •  Logic Rendered from

Models: 90% Less Code •  Model Updates

Implemented in Hours
