2 Any Function Virtualization (FV) Network function virtualization of interest to Network service providers But the same concept can be used by any other industry, e.g., financial industry, banks, stock brokers, retailers, mobile games, Everyone can benefit from: Functional decomposition of there industry Virtualization of those functions Service chaining those virtual functions (VFs) or Apps 2
3 Overview SDN then and now Software Defined Multi-Cloud 1. Internet of Things and Smart Cities 2. Mobile Traffic Explosion: NFV 3. Any Function Virtualization 4. Mobile Edge Computing OpenADN Multi-Cloud Management Service Function Placement Problem 3
4 Software Defined Networking (SDN) SDN was invented in 2009 Then: SDN: Separation of control and data planes Centralization of Control Standard Protocol between the planes Now: Software Defined Everything (SDE) = Disaggregation of hw/sw Commodity hardware Open Source Sw on commodity hw Service industry Controller replaced by Orchestrator Centralization of policies Control Plane Data Plane Data Plane Orchestrator SW HW SW HW Ref: D.

5 IoT is a Cloud Data ($) Mine Ref: 5
6 Trend: Micro-Cloud Computing Cloud computing was invented in 2006 Then: Cloud = Large Data Center Multiple VMs managed by a cloud management system (OpenStack) Today: Cloud = Computing using virtual resources µcloud = Cloud in a server with multiple VMs. Each VM with Multiple Containers Multiple Services Ref: Raj Jain and Subharthi Paul, "Network Virtualization and Software Defined Networking for Cloud Computing - A Survey," IEEE Communications Magazine, Nov 2013, pp , 6

Anthony Chan, "Mobile Edge Computing - an important ingredient of 5G Networks," IEEE Softwarization Newsletter, March 2016, 8 Network
9 Trend: Micro-Services All major applications, such as, Facebook, Netflix, etc. consist of a number of micro-services that are instantiated on demand on virtual machines Users Micro-Clouds Regional Clouds Local Clouds Network 9

15 Summary 1. SDN is about orchestration and centralization of policy. Not about separation of control and data planes. 2. Value of IoT is in the data it produces. Internet of things are leading to clouds everywhere 3. Clouds are getting smaller, Carriers and enterprises moving to clouds multi-cloud applications. 4. Software Defined Multi-Cloud Orchestration: Our Multicloud application management system (MCAD) allows policy-based deployment and management of multi-cloud applications. 5. Service function placement problem is NP complete. Challenges included delay constraints, WAN Link bottlenecks, and affinity 15
