be consumed
Nova-compute: Manages communication between

Typical Non-High Available
deployment using VLANs
Add compute nodes as you
grow
All services on one server
Hardware Firewall required
for management network
and customer networks

Software defined networking (SDN)
Routed vs Flat vs VLAN
Using hardware firewalls with VLANs to isolate tenant
networks
Non-dhcp networking
All routed public subnets
One or many subnets per tenant
Multiple logical interfaces per tenant per instance
Integrated into Horizon
Quantum Networking
