THE CHALLENGE! Time to Market at the speed of light WEEKS Physical DAYS Virtual MINUTES SDC 2008 2012 2014
THE CHALLENGE! How to differentiate? SCALABILITY AUTOMATION SELF-CARE INTEGRATION QUALITY OF SERVICE REQUIREMENTS THREATS SHADOW IT MEGA CLOUDS TRENDS DISTRIBUITED SERVICES MOBILITY HYBRID ENVIRONMENTS SOFTWARE IS KING
SOLUTION? fast & simple
SOFTWARE DEFINED CLOUD Main Characteristics TIME TO MARKET SCALABILITY QUALITY OF SERVICE TOTAL COST OF OWNERSHIP Accelerate introduction of new services and functions Deploy new workloads Full stack Resource Automation Self Care and Self Provision capabilities using standard set of APIs Architecture Simplification Cross boundaries/limitations of traditional network solutions No geographic restrictions (physical resilience, data replication) Centralized control of resources Holistic monitoring of services Resource optimization on a global vs site-specific scale Reduce OPEX Reduce CAPEX More cost-efficient services
SOFTWARE DEFINED CLOUD History... Past Yesterday Today Dedicated hardware Very high maintenance, storage and cooling costs Waste of resources due to low utilization % Complex architectures Proprietary and closed environments Difficult integration Server Virtualization, multi-tenancy Partial automation and self-care Increase % of resource utilization Energy consumption / environmental Concerns L2 scalability / extension Bandwidth growth LAN/SAN Consolidation (?) No L2! Open interfaces / APIs Network Virtualized and Software Defined Storage Virtualized and Software Defined Hybrid User Experience Geographic redundancy of virtualized services

SDN, NFV or BOTH?? OUR VISION Network Element Actual Mode of Operations Application Layer Manual Interface Infrastructure & Control Layers Network Element Business Applications Network Element Network Element Applications have little knowledge, control, or visibility of underlying network and resources Application Layer Control Layer Infrastructure Layer Network Element Network Element SDN SDN Control Software Business Applications API API API Control Data Plane Interface (e.g., Open Flow) Network Element Network Services Network Element SDN provides APIs and a control layer that explicitly links applications to the physical network
SDN, NFV or BOTH?? OUR VISION SDN NFV REASON FOR BEING TARGET LOCATION Separation of control and data, centralization of control and programmability of network Campus Data Center Cloud Relocation of network functions from dedicated appliances to generic servers Service Provider Network TARGET DEVICES Commodity servers and switchs Commodity servers and switchs INITIAL APPLICATIONS Cloud orchestration and networking Routers, firewalls, gateways, CDN, WAN accelerators, SLA assurance
