5 Putting Pressure on Networks to Scale Applications double every 4 years Data volumes double every 18 Months OpEx costs double every 8 years F5 Networks, Inc. Source: IDC Directions, Battle for the Future of the Datacenter: The Role of Disaggregated Systems, March

6 Challenges in Scaling Modern Data Centers Agile Efficient Flexible High network complexity Years of deploying point products have resulted in complex, fragile network topologies Infrastructure integration difficulties Each with its own unique set of CLI, GUI, API, and integration methods Difficult to manage lots of boxes that must be balanced against unique upgrade, patch, and maintenance schedules F5 Networks, Inc. 6

7 Challenges in Scaling Modern Data Centers Architect Clients Network Engineers and Admins Manual and Scripted Configuration Data Plane Application Time consuming Error prone process Difficult to debug Router Switch LB Firewall VEs F5 Networks, Inc. 7

8 Enterprise Needs a New Answer Agile Dev DevOps SDN Rapid development of customer desired applications Rapid deployment, Accelerate time to market Operationalise the Network, Accelerate time to market Rapid deployment and network operations Network operations F5 Networks, Inc. 8

9 What is SDN? OpenFlow? L2-3 Switch Control? Overlay/Virtual Networking? Service Chaining? Virtualisation? Commoditisation? Programmability? Abstraction? Yes! F5 Networks, Inc. 9

10 Definition of SDN: SDN is a family of architectures (not technologies) for operationalising networks with improved time to market, reduced risks, and reduced operating expenses by centralising control into a control plane that programmatically controls and extends all network data path elements and services via open APIs. F5 Networks, Inc. 10

11 Operationalising the Network SDN transforms IT by addressing factors that cause higher costs for, slows down deployment of, and result in customer dissatisfaction with applications Automation Abstraction Standardisation Programmability Long time to deploy new services High network complexity Difficult to manage lots of boxes Low customer satisfaction SERVICE VELOCITY NETWORK AGILITY REDUCED OPEX APPLICATION DRIVEN F5 Networks, Inc. 11
