Several Topologies
Topology
1-3 is been tested
1. Single Node , Network Combine with our corporate network
All nova-component in one host , and the instance network is same as corporate network.
2.Multi Compute nodes
Two major parts , one host include most of services with a nova-compute cluster
3.Multiple servers

| Machine | NICs | Networks |
| 1 | 1 or 2 | 1 or 2 |
2.Multi Compute nodes
Two major parts , one host include most of services with a nova-compute cluster| Machine | NICs | Networks |
| 1 controller | 2 or 3 | 1 to 3 |
| many compute nodes | 1 or 2 | 1 or 2 |
3.Multiple servers
All traffic through nova-network host
| Machine | NICs | Networks |
| Nova-network | 2 or 3 | 2 or 3 |
| Nova-API | 1 | 1 |
| Compute nodes | 1 | 1 or 2 |
Instance traffic through nova-network , but API service direct connect from corporate network
Machine NICs Networks Nova-network 2 or 3 2 or 3 Nova-API 2 1 or 2 Compute nodes 1 1 or 2
- Production topology from StackOPS
This Topology has a problem , once nova-network dead , All trafic will lost. But it's interesting , I guess instance will be fine while nova-network restart.
I want to figure out a method of instance's gateway....
If we add a way to use router instead of nova-network host as gateway, it will be better .
But instance can not get metadata from api-server which is another problem.
