Azure RM Module is deprecating soon, I made new version that using AZ Module.
Also Used Managed Identity(System Identity) so that Giving Credential to Automation is more easier than before.
This runbook start/stop VM based on your resource group.
You can see parameters named Azureresourcegroup and Action.
on Azureresourcegroup, you pass your rg name(ex: test-rg) on Action, you pass what action you want to do(1. Start 2. Stop)
Hope you guys use it well
Thanks.
