Martin Casado Introduction. When we talk about virtualization, we are lying a little bit. It’s very important to know what’s this lie is. We have to work with 3 decades of madness. We have decoupled VM from the compute but we haven’t decoupled them to the physical network. Look at the addressing, the default gateway, the subnet, … it comes from the physical world. Resulting in : Slow provisionning limited placement Mobility is limited Hardware dependent Operationaly intensive The basic concept of network virtualization is the same as the compute one, a thin layer of software that sits in between. Virtual network will look exactly the same for a VM. If you have this virtual network a lot of the previous problems will disapear. You can move a VM anywhere you want. The physical won’t go away but we are agnostic. It’s not about protocols: STT, VXLAN, at the end of the day it’s about the virtual abstraction. We want to support any physical network. ...
