Tier="F1"
Hub="cli-hub" Device="DirectDevice"

# Using Powershell
$ResourceGroup,$Location="IoTtest","eastus"
$Tier="F1"
$Hub,$Device="cli-hub","DirectDevice"

# Create a hub
az group create --resource-group $ResourceGroup --location $Location
az iot hub create --resource-group $ResourceGroup --location $Location --name $Hub --sku $Tier 

# Create a Device
az iot hub device-identity create --hub-name $Hub --device-id $Device
