“Software is eating the World.” Marc Andreessen 2

Software is eating the World Hardware/Physical Sun Microsystems Blockbuster Tower Records Barnes & Nobles Software Microsoft Netflix Itunes Amazon 3 This is true for networking as well.

Virtual Ports outnumber Physical Ports in the Data Center Math: 2-3 physical ports/server 1-2 virtual ports/VM Assume 50% of HW virtualized, 5 VM’s average Over 65% of ports are virtual. 4

Virtual Ports are the new Network Edge Edge Ports are more Important than ports in the core Services are pushed to the edge – Easier to maintain state close to the edge – Keep the core simple and fast (routed, tags) Virtual Ports have Unique Advantages Only place to intercept inter-VM traffic State that scales out with number of VMs “Golidlocks” zone that is a separate security zone from guest VM, but can access guest VMresources 5

Decoupling Hardware and Software 6 vSwitch Virtual Network Innovate at Software Speed Rich Edge Services Security Physical Network Innovate at Hardware Speed Performance and Scale Keep it Simple

Why is VMware supporting OVS? 11

OpenStack/KVM Data Center 12 KVM Linux KVM Linux (Guest) Apache Linux (Guest) Apache KVM Linux KVM Linux (Guest) Apache Linux (Guest) Apache Open vSwitch OpenStack

Our take on OVS We are committed to keeping Open vSwitch open We have no illusions about what that means: – Used by our competitors. And that’s ok. – Vast majority of people using OVS are doingit without a VMware product. That’s ok too. Our goal is to keep Open vSwitch is a production quality foundation for great SDN products and systems. 13

How is Open vSwitch doing? 14

Open vSwitch and OpenStack OVS is #1 for OpenStack 43% of Production 49% of Dev/QA 40% of PoC OVS more popular than the “default”. 15 Source: 2014 OpenStack Survey
