  1. 1. EMPOWERING SDNSOFTWARE-BASED NETWORKING & SECURITY FROM VYATTA Cloud Expo Santa Clara - 2012 Scott Sneddon Chief Solutions Architect @ssneddon
  2. 2. Who is Vyatta? Leader in software-based networking Founded in 2006 on the belief that the future of networking will be in software
  3. 3. Vyatta is… Router Firewall VPN OSPF, BGP Stateful, NAT IPSec, SSL
  4. 4. Vyatta is… Software-based Networking CLI, API, GUI
  5. 5. Vyatta is… Software-based Networking CLI, API, GUIRemote Access API•  Programmable•  RESTful•  Full Control
  6. 6. Flexible Deployment CLI, API, GUI CLI, API, GUI OR Hypervisor   x86  Server  
  7. 7. Many UsesData Center Cloud Remote Office Security Multi-tenancy Consolidation Remote accessTraffic Optimization Cost Reduction Multi-tenancy
  8. 8. Let’s talk about SDN
  9. 9. What is SDN?“…programmable networks (or more precisely,network elements that can be configured througha reasonable and documented API)…” – Ivan Pepelnjak, ipSpace.net“Software Defined Networking (SDN) is anemerging network architecture where networkcontrol is decoupled from forwarding and isdirectly programmable…” – Open Networking Foundation
  10. 10. What SDN isn’t…We  s0ll  need  smart  network  design.  Maybe  smarter  then  we  did  before.   There’s  more  to  it  then  just  OpenFlow.  
  11. 11. So, SDN is all about…•  Network Programmability –  API interaction with network elements•  Separation of Control Plane and Forwarding Plane –  Infrastructure Agnostic –  Forwarding Plane can be Software or Hardware•  Integration with higher-order Orchestration platforms –  OpenStack, CloudStack, vCloud Director
  12. 12. Traditional Network Control   Control   Forwarding   Forwarding   Control   Control   Forwarding   Forwarding   Control   Control   Forwarding   Forwarding

  15. 15. How is SDN used today?•  Carrier-grade OpenFlow –  WAN Programmability/OpenFlow “paths”•  Datacenter Network Virtualization –  Overlay networks •  Tunnels – VXLAN, STT, GRE •  Solves VLAN exhaustion & L2 extensibility –  Programmability of L2 segments – OpenFlow –  Cloud infrastructure •  Per-tenant network segments & security

  17. 17. Why are SDNs important?•  Datacenter network topologies are changing (or they need to change) –  Server Density –  Changes in traffic flows –  Capital cost of infrastructure needs to decrease –  NetOps needs to keep pace with DevOps•  It’s about the apps… –  DevOps movement and application development velocity We haven’t removed the need for segmentation and security We haven’t removed the need for network engineering
  18. 18. DevOps?•  “Devops  is  a  sobware  development  method  that  stresses  communica0on,   collabora0on  and  integra0on  between  sobware  developers  and  informa0on   technology  (IT)  professionals”       -­‐  hep://en.wikipedia.org/wiki/DevOps  •  “…these  opera5onally  aware  engineering  teams  and  engineering-­‐aware   opera5onal  teams  must  have  buy  in  at  the  top  because  people  who  code  generally   cost  more,  so  hiring  opera0onal  team  members  who  code  require  a  bigger  budget.”      –  Pedro  Canahua0,  Facebook  (hep://gigaom.com/cloud/how-­‐facebook-­‐ solves-­‐the-­‐it-­‐culture-­‐wars-­‐and-­‐scales-­‐its-­‐site/)

  20. 20. DevOps for NetOpsBuild  a  VLAN  and  subnet  on  a  Juniper…   Build  a  VLAN  and  subnet  on  a  Brocade…  interfaces  {   vlan  4  name  customer_a      ge-­‐0/0/9  {    untagged  ethe  1/4                  descrip0on  ”customer  a";    router-­‐interface  ve  4                  unit  0  {   interface  ve  4                          family  ethernet-­‐switching  {    ip  address  10.160.0.10/16                                  port-­‐mode  access;                                    vlan  {                                          members  vlan4;                                  }                          }                  }          }    vlan  {                  unit  4  {                          family  inet  {                                  address  10.160.0.9/16;   Not  bad,  but  it  could  be  beeer                          }                  }  }  vlans  {    vlan4  {                  l3-­‐interface  vlan.4;          }  }

  22. 22. How does NetOps get there?•  Knock down organizational boundaries•  Expand our knowledge base as network engineers –  Augment that CCIE with a little Python•  Look beyond plumbing –  Think “Network as a Service”•  Better operational models for repetitive tasks –  API’s to present auto-provisioned services (with constraints) to your customers
  23. 23. The SDN (R)evolution
