2 Key Market Trends and Challenges 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 All of this requires successful, flexible automation But complexity has destroyed many automation initiatives 2

3 Barriers to Successful Automation Growing Complexity Proliferating devices and service types Heterogeneous environments Legacy IT and automation can t keep up Lack of Visibility and Granular Control Data quality issues No transactional control Complex rollbacks and remediation Current Automation Complex, Rigid, Fragile Hardcoded logic flows and CLI templates Fragile programmatic adapters One-off solutions not repeatable or reusable High Fallout Ratios and Broken Configurations = Higher Costs, Slower Service Activation 3

4 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 4

5 Cisco NSO Enabled by Tail-f Agile Strict YANG Models for Services & Devices Logic Rendered from Models: 90% Less Code Model Updates Implemented in Hours Automated Single Network Abstraction Layer Active Network View: Always in Sync, Minimal Fallout All Use Cases on All Devices Across Vendors Reliable End-to-End Atomic Transactions Control Minimal Impact on Network via Minimum Diff. Engine Proven in Tier 1 Deployments Model-Driven Automation for Multivendor Brownfield Environments Support DevOps and Modern Ways of Working with Any Service Type 5
