hello,
Took a quick look at the diagram:
Almost everything is possible with a css:
- But the servers should never be directly connected to the css.
- The CSS is a loadbalancer so having 1 proxy and 1 dns on 1 css has no use
- What you first should do is draw the flows which you want to have
- You should decide what type of redundancy that you want: box2box / vip redundancy
Good luck
Dimitri
