The difference between the OpenStack architecture described in the previous section and the architecture explained in this section is that we are using the Neutron networking service instead of legacy OpenStack networking. Secondly, in this section, we are focusing on high availability of the solution.
Let's now take a look at the node hardware specifications for the basic architecture with OpenStack networking:
