I am unable to deploy to Azure after I added one more role
The VM size (or combination of VM sizes) required by this deployment cannot be provisioned due to deployment request constraints. If possible, try relaxing constraints such as virtual network bindings, deploying to a hosted service with no other deployment in it and to a different affinity group or with no affinity group, or try deploying to a different region.
The CloudService is new. I was expecting that the resources will be scaled to fit my needs.
