Transcript

  • 1. How to Get Started withNetwork VirtualizationWhy it matters, how it will affect you, and some key technologiesto knowScott Lowe, VCDX 39vExpert, Author, Blogger, Geekhttp://blog.scottlowe.org / Twitter: @scott_lowe
  • 2. Before we start•Get involved! Audience participation is encouraged andrequested.•If you use Twitter, feel free to tweet about this session (usehandles @MyVMUG or @WPVMUG or hashtag #WPVMUG)•I encourage you to take photos or videos of today’s sessionand share them online•This presentation will be made available online after the event
  • 3. Your name is familiar...
  • 4. •What is network virtualization?•How is it similar to compute virtualization?•Why does network virtualization matter to me?•How does network virtualization change my job?•How does network virtualization affect my networking group?•What are some key technologies I should know?•What are the key components of network virtualization?Agenda
  • 5. “If you can’t explain it simply, youdon’t understand it well enough.”- Albert Einstein
  • 6. •A combination of technologies to support the creation of virtual(or logical) networks•A virtual network is a network that can be created, modified, anddestroyed without any interaction with physical network assets•Network virtualization:•Decouples virtual networks from physical networks•Reproduces the physical network faithfully in the virtualnetwork•Automates the creation of virtual networks programmaticallyWhat is network virtualization?
  • 7. What is network virtualization?PhysicalInfrastructureCompute Virtualization Abstraction LayerNetwork Virtualization Abstraction Layer
  • 8. •It works on any physical hardware (only requires an IP fabric)•Decouples virtual (logical) networks from underlying physicalnetworks (hardware independence)•Does not require changes to applications/workloads in order tosupport network virtualization•Doesn’t preclude the use of hardware support to enhance thevirtualization functionality (e.g., hardware offloads)How is it similar to computevirtualization?
  • 9. •Other than jumping on the buzzword bandwagon?•It makes it easier to provision new logical networks•It makes it faster to provision new logical networks•Logical networks can be quickly created, modified, and deletedas needed without involving the physical network•It brings network functionality closer to the workloadsWhy does networkvirtualization matter to me?
  • 10. •It actually simplifies your job as a vSphere admin•Youll be responsible for creating, modifying, and deleting virtual(logical) networks, typically from within your cloud managementsystem•You are abstracted away from the specific technical details ofhow the network provides the functionality you need for yourworkloadsHow will network virtualizationchange my job?
  • 11. •It actually simplifies their job•The networking group no longer needs to worry about workloadprovisioning tasks•Instead, they can focus on the key values of the network inmoving data from point A to point B•Performance•Reliability•Cost-effectivenessHow will network virtualizationaffect my networking group?
  • 12. How will network virtualizationaffect my networking group?WANInternetCompute Racks Infra Racks Edge RacksL2L3
  • 13. What are the key componentsof network virtualization?
  • 14. •Open vSwitch (OVS)•OpenFlow•OVSDB (and possibly OF-Config)•Network encapsulation protocols (STT, VXLAN, GRE)What are some keytechnologies I should know?
  • 15. Questions &answers
  • 16. Thank you!Don’t forget to provide feedback to your VMUG leaders on thissession.
