# Take a note that in this task VMs are deployed without public IPs and you won't be able
# to connect to them - that's on purpose! The "free" Public IP resource (Basic SKU,
# dynamic IP allocation) can't be deployed to the availability zone, and therefore can't 
# be attached to the VM. Don't trust me - test it yourself! 
# If you want to get a VM with public IP deployed to the availability zone - you need to use 
# Standard public IP SKU (which you will need to pay for, it is not included in the free account)
# and set same zone you would set on the VM, but this is not required in this task.
