Another way to do this would be the aforementioned aliases, just allow one
alias per site.  So you could say

ec2:small  "type=m1.small"
canonistack:small "mem=2G cpu-cores=1"

then you could do

juju deploy wordpress --constraints alias=small

and it would do the right thing whether it deployed to ec2 or canonistack.
