Agenda • Research Goals • Demographics • Why It Was Time for This Research • What Is SDN? • Enterprise Network Management System Readiness • New Requirements for Managing Enterprise SDN • Service Provider Network Management System Readiness • New Requirements for Managing Service Provider SDN • The Path Forward With Management Systems • New SDN Skills for Networking Professionals • Business Goals for SDN Adoption Slide 6 © 2016 Enterprise Management Associates, Inc.
Research Goals • Establish a definition of SDN • Assess the SDN readiness of existing network management systems • Identify new network management system requirements for SDN • Examine organizational impacts • Explore use cases, benefits, and business impacts of SDN adoption • Technology Impacts Assessed • Enterprise  Data-center SDN underlay, data-center SDN overlay, campus SDN, SD-WAN, NFV • Service Provider  SDN, NFV Slide 7 © 2016 Enterprise Management Associates, Inc.
Research Demographics • Surveyed 226 early SDN adopters • Organizations that have started production SDN deployments or plan to do so within 12 months • 150 enterprise IT professionals  51% IT management roles  49% IT staff roles • 76 service provider network infrastructure professionals • 46% from North America, 33% Europe, 20% Asia- Pacific, 1% Middle East-Africa • Wide distribution of company size • 24% Small (250-999 global employees) • 38% Midsized (1,000-4,999) • 38% Large (5,000 or more) Slide 8 © 2016 Enterprise Management Associates, Inc.
Why It Was Time for This Research • Plenty of evidence that SDN’s time has come • EMA research in 2014 found 18% enterprise adoption rate • Cisco claims 1,100 customers of ACI • VMware claims 700 customers of NSX • AT&T serves millions of mobile subscribers over SDN* • Google, Microsoft, and many others have shared details of production SDN use in data centers, WANs • SDN conversation tends to focus on architecture, use cases • Limited discussion of operationalizing SDN Slide 9 © 2016 Enterprise Management Associates, Inc. *Source: FierceWireless.com, Oct. 2015
What Is SDN? • Early adopters define SDN by highlighting essential characteristics of solutions they implement: ① Centralized controller ② Low-cost hardware ③ Fluid network architecture • Least important elements of SDN : • Decoupled control plane and data plane • Intent-based networking • Enterprises emphasize centralized controller and fluid network architecture • Service providers emphasize low-cost hardware and abstraction of physical & virtual network elements Slide 10 © 2016 Enterprise Management Associates, Inc.
What Is SDN? (continued) • A different definition for software-defined WANs • The three defining characteristics of SD-WAN  Cloud-based network and security services  Centrally programmable network  Hybrid WAN transport • Network functions virtualization (NFV) • A use case of SDN or a related technology • Systematic virtualization of network functions traditionally delivered in hardware appliances  Requires new management and orchestration framework  Applicable to service providers and enterprises Slide 11 © 2016 Enterprise Management Associates, Inc.

New Requirements for Managing Service Provider SDN Service provisioning and activation tools ① End-to-end management across physical and virtual network elements ② Policy specification based on modeling of network configuration and operational state ③ Service activation based on modeling of network configuration and operational state Slide 17 © 2016 Enterprise Management Associates, Inc.
New Requirements for Managing Service Provider SDN (continued) • Operations support and readiness tools ① Software-based implementation of approved network and service changes ② Inventory management of virtual network functions and virtual networks • Service assurance tools ① End-to-end service quality management across physical and virtual resources ② Bidirectional integration with SDN controllers ③ Increased automation of network optimization Slide 18 © 2016 Enterprise Management Associates, Inc.
The Path Forward for Management Systems • Enterprises and service providers are split on how to address management system gaps • No consensus on a path forward  Modify existing tools  Use new tools separately  Use a combination of new and existing tools • What should you do? • Assess manageability of SDN solutions  Is your SDN vendor partnering with management system vendors? • Ask network management vendors about their SDN roadmaps  Is your incumbent vendor addressing the new functional requirements identified in this research?  Can you complement your management systems with a new tool? Slide 19 © 2016 Enterprise Management Associates, Inc.
New SDN Skills for Networking Professionals • Top 4 priorities for enterprise IT pros • Cloud management system expertise (OpenStack, CloudStack, etc.) • New network protocol knowledge • Programming skills (not scripting) • Software development skills • Top 4 priorities for service provider networking pros • Software development skills • Programming skills • Cloud management system expertise • New network protocol knowledge • Lowest priorities • DevOps automation tool expertise (Puppet, Chef, etc.) • Certifications Slide 20 © 2016 Enterprise Management Associates, Inc.
Business Goals for SDN Adoption • Top goals for enterprises • Improved end-user productivity (28%) • Revenue growth (21%) • Improved customer/brand loyalty & retention (13%) • Top goals for service providers • Improved end-user productivity (28%) • Revenue growth (25%) • Operational trust (17%) • “Reduced expenses and costs” is the lowest priority for all organizations Slide 21 © 2016 Enterprise Management Associates, Inc.
The Impacts of SDN on Network Management • Early SDN adopters value a centralized controller and low-cost hardware • Existing enterprise and service provider network management systems are not ready for SDN • Early adopters have identified the management capabilities they need in their tools • Networking organizations need to have a manageability discussion with SDN solution providers and management vendors • Networking pros are indeed learning programming and software development skills • Early adopters say SDN will boost productivity and grow revenue • Cost reduction is not a business driver Slide 22 © 2016 Enterprise Management Associates, Inc.
