Chapter 7. Building Networks and Routers

In the previous chapter, we learned that Neutron routers provide connectivity between user-created tenant networks and external networks such as the Internet using network address translation. In this chapter, we will take a look at some basic virtual network architectures and will showcase the traffic flow from client workstation to virtual machine instance via fixed and floating IPs.

Basic network architectures and functions that will be covered include:

  • Single-homed instances connected to provider networks
  • Single-homed instances behind Neutron routers
  • Source NAT
  • Floating IP

So sit back, get comfortable, and let's take a look at some networks and routers.
