  • 1. IT RoadShow, Denver, June 2014 Your Speaker • Dave Michels • F100 Corporate IT Leadership • Principal Analyst TalkingPointz • Analyst and Media • TalkingPointz • Founded2002 • Exclusive focus on Enterprise Communications @DaveMichels
  • 2. IT RoadShow, Denver, June 2014 The Familiar trend of virtualization Servers Desktops Networks
  • 3. IT RoadShow, Denver, June 2014 • Agility • Isolate Applications • Improve Disaster Recovery • Faster Provisioning • Reduce cost of Support • Green Virtualization Server Virtualization Benefits Desktop Virtualization Benefits • Agility • Isolate Applications • Improve Disaster Recovery • Faster Provisioning • Reduce cost of Support • Green
  • 4. IT RoadShow, Denver, June 2014 Network Virtualization ● Agility ● Isolate Applications ● Improve Disaster Recovery ● Faster Provisioning ● Reduce cost of support ● Green
  • 5. IT RoadShow, Denver, June 2014
  • 6. IT RoadShow, Denver, June 2014 SDN: What is It? ● Software Defined Networking ● Commercialized from work done at Berkeley and Stanford Universities (2008) ● Decouples the logic and forward planes ● Centralizes network state and intelligence ● Network becomes an abstract resource
  • 7. IT RoadShow, Denver, June 2014 Control vs. Data Control Plane • CPU intensive • Low bandwidth • General purpose hardware • Can be centralized Data Plane • Low CPU • High bandwidth • Specialized hardware common • Needs to be distributed
  • 8. IT RoadShow, Denver, June 2014 OpenFlow ● Overlay New Protocols Without Disrupting Underlying Fabric ● Provides Communications Between Network Intelligence and Network Gear ● Attractive in the Data Center o DynamicInfrastructure as a Serice o Made Networking Behave Like Software ● The Attraction of Commodity Hardware ● One (of many) approachesto SDN
  • 9. IT RoadShow, Denver, June 2014 Data Plane (hardware) OpenFlow AgentControl Plane (software) Controller Network Switch FlowTables Match Rule Action CountersFlow Table Rules: OpenFlow under the hood 1. Forward 2. Modify 3. Encap / decapsulate 4. Drop, etc.
  • 10. IT RoadShow, Denver, June 2014
  • 11. IT RoadShow, Denver, June 2014 SDN Today ● Almost every technology vendor in the networking arena now has an SDN Angle ● Highly disruptive ● Immature ● Data Center Centric ● Southbound Standards ● Northbound APIs
  • 12. IT RoadShow, Denver, June 2014 East, West ● Creates the benefits of a Layer 2 network ● Far more efficient use of BW and resources ● SDN could enable distributed switches to act as routers, firewalls, load balancers
  • 13. IT RoadShow, Denver, June 2014 Data Center Impetus ● As server virtualization has increased, so has complexity of dynamic infrastructures ● Tried and True IP Routing Breaks-Down ● SDN Provides Flexibility to Set Attributes Across the Network ● SDNs are the Natural Counterpart to Server Virtualization ● The Promise of Orchestration
  • 14. IT RoadShow, Denver, June 2014 Orchestration Concerned with lifecycle management operations • Service instantiation • Health monitoring and repair • Elastic scaling • VM migration Automation - Rather than perform manually Openstack: Collaborative effort of developers and cloud companies to create a single cloud operating system
  • 15. IT RoadShow, Denver, June 2014 5 Key Benefits to SDNs 1. Flexibility and Holistic Management 2. Provisioning Speed and Agility 3. Improved and More Granular Security 4. Efficiency - and Lower Operating Expenses 5. Virtual Network Services, Lowered CapEx
  • 16. IT RoadShow, Denver, June 2014 SDN Won’t Be Contained to DC ● Enterprise Wide Implications ● Unified Communications o Wired/Wireless o DynamicBW IM/Voice/Video o Any Device: Desktop/Tablet/Mobile/xDevice ● APIs make Apps Everywhere ● 60-80% of Poor End User Experience due to Network Issues
  • 17. IT RoadShow, Denver, June 2014 SDN: It’s Gonna Be Big ● 2018 Market Forecast for SDN: $35B ● CAGR: 62% over 5 Years ● 2017: 60% of Enterprises will automate the provisioning of Security Controls ● 75% of Gartner Clients Report they are Thinking About or Evaluating SDNs
  • 18. IT RoadShow, Denver, June 2014 The Disruptive Element ● Traditional Approach Favors Single Vendor Solutions ● Cloud-Scale Data Centers Experimented with Open Source Controllers w/ Commodity Hardware ● Programmability of previously rigid vendor networks. ● Reduced vendor lock ● Open Source initiatives
  • 19. IT RoadShow, Denver, June 2014 Open Source Initiatives ● OpenDaylight is a community-led, open, industry-supported framework under the Linux Foundation ● Project Floodlight is the Open SDN Open Source Project supported by Big Switch Networks ● Indigo is an open source project aimed at enabling vendors to support OpenFlow on physical and hypervisor switches ● OFTest is a testing framework and test suite for OpenFlow compliance testing
  • 20. IT RoadShow, Denver, June 2014 Agility in Practice ● Rapidly Create & Deploy Proof of Concept and Test Networks ● Faster Response to New Techs ie. Mobile ● Security and Compliance governed From Central Location ● Lowers Operational Spend and CapEx
  • 21. IT RoadShow, Denver, June 2014 SDN is Progressive….but Immature ● Lack of standards for full device control - no Northbound API Std (to Appl Layer) ● SDN Introduces New Security Concerns o New Risks with Centralized Controller o API Exposure to Attack ● Think about SDN Long Term Implications
  • 22. IT RoadShow, Denver, June 2014 Take-Aways ● SDN Emerging Tech of Growing Importance ● SDN Will Have Disruptive Impacts ● Will facilitate agility and reduce costs ● Early Still - Barriers to Adoption Exist ● SDN Standards Are Evolving Slowly
