Multi Tier App deployment on vCAC/RA blueprint

Question

Hi all,
is it possible to land a multi tier app on a vCAC infra blueprint where I get to chose which tier (so say 3 tiers separated via VLANs and f/w provided by NSXv/vShield in the vCAC blueprint) the app components land on from within App Director?
So the web vm is in Vlan 101, while the db in in vlan 3 etc?
If not, what would be a recommended workaround please?
Cheers

You can use component dependencies to share property values between components. E.g.
Say I have a node which will have 2 app components on it.
Component c1 has properties
p1
p2
Component c2 has properties
p3
p4
p1copy
p2copy
If you look in the upper right of the Blueprint builder there is a chain icon which lets you define dependencies between components (either on the same nodes or different ones)
With a dependency in place between my example components (c2 depends on c1) we can then bind the p1copy property value in c2  to the value in c1 in the following notation
self:c1.p1
This expression breaks down as
<node name>:<component name>:<property name>
Quite simple and very powerful
Also, there are some built-ins for each node such as
self:ip
self:hostname
etc.
This is all mostly in the docs but you'll wrap your head around it pretty quickly if you play about with it
