1 The real SDN Power Materializes itself with Application Defined Networking Pascale Vicat-Blanc, PhD CEO - Lyatiss Santa Clara, CA USA April

2 This session objectives What is Application Defined Networking? Typical Use Case: Cloud ADN in the Stack Benefits ADN - SDN Joint Value Santa Clara, CA USA April

3 Application Delivery Challenges More and more Applications are running in the Cloud (video, music, images, search, social, big data) But they are suffering from: Bad performance under load Inconsistent response time Slow content delivery Poor user experience Networking is responsible for lot of these issues 3

4 Application Defined Networking Goal: provides Application-driven Elastic Networking Application adapts the Networking to its needs 1. Dynamically 2. Holistically 3. Transparently To optimize performance, cost and experience. 4

5 Application Defined Networking Principles: Tight coupling of the application and its graph of resources Integration of monitoring, analytics and orchestration Continuous adaptation to application goals

6 Typical Use Case: Cloud Santa Clara, CA USA April

7 Cloud Promise and Today s Reality Expected Benefits Lower costs Cap-Ex free computing Deploy projects Faster Scale as Needed Lower Maintenance costs Resiliency & Redundancy Reality Uncontrolled costs Cap-Ex free computing Deploy projects Faster (?) Scale as Needed (?) Lower Maintenance costs (?) Resiliency & Redundancy (?) Posted on September 13, 2010 by Mike Klein Cloud Operations are becoming a nightmare to manage! Santa Clara, CA USA April

13 SDN Value Proposition SDN reduces operational complexity (Gartner 2012) SDN is a major aid to automated provisioning, configuration and network management. 1. SDN simplifies the management and reconfiguration of physical and virtual network. 2. SDN creates an abstraction of the networks which make them programmable.

14 SDN Promises SDN will enable simple configuration accross geographic boundaries, multitenancy, centralized network management, multiple IP adresses, VLAN tag allocation, QoS, dynamic cross-connections, federation of public and private networks, operations with virtual storage and compute processing Santa Clara, CA USA April

15 ADN + SDN: A Powerful Combination SDN provides the «instruction set» for: Scalable connectivity High Security High Manageability Personalization Predictability Low latency ADN codes this «network machine» to automate Cloud optimization and meet Application goals. 15

17 Example: Multi-tier application Flows Front End Back End Data Base Network Path Network Challenges: High Security Low Latency Manageability 17

18 Example: scalability & elasticity Scale out Network Challenges: High scalability High Manageability Predictable performance 18

19 ADN SDN : joint value 1 ADN discovers Application flows 4 ADN decides, orchestrates adaptation 5 SDN reconfigures the Network 2 SDN monitors Network Performance 3 ADN detects and locates Issues ADN+SDN Automated Cloud Optimization Santa Clara, CA USA April
