Networking Questions SDN

Hi All,

I’m curious on how to complete the following.

Just some “googable” topics or references would be awesome! Ultimately I want to automate all this. However, I’m stuck trying to figure out the basic network/template deployment options that would complete the diagram in OpenNebula. The part I’m having trouble with is using the exact same IP addresses for each template deployed and then source NAT’ing each environment to a public IP.

Thanks!
