Create the resource groups in different regions, then run the global deployment, which deploys Traffic Manager with optimized routing and failover to traffic in different regions:

az group create -g global-rg --location EastUS
az group create -g app-eastus-rg --location EastUS
az group create -g app-westus-rg --location WestUS
az group create -g app-westeu-rg --location WestEurope
az group create -g app-india-rg --location CentralIndia
az group create -g app-asia-rg --location EastAsia
az deployment sub create --location EastUS --template-file global-app.json

Cleanup

az group delete -g global-rg -y --no-wait
az group delete -g app-eastus-rg -y --no-wait
az group delete -g app-westus-rg -y --no-wait
az group delete -g app-westeu-rg -y --no-wait
az group delete -g app-india-rg -y --no-wait
az group delete -g app-asia-rg -y --no-wait
