I’ve been writing a bit about Azure Resource Manager. Here’s a reference to my posts for easier access:
Azure Migration from ASM to ARM – The Journey to the Center of The Cloud Series:
Journey to ARM–Design and Migrate
Journey to ARM–Part II – Creating the VPN gateway
Journey to ARM–Part III – Copying Storage
Journey to ARM–Part IV – Creating a VM from an existing VHD
Journey to ARM – Part V – Adding an external IP to an existing VM
Journey to ARM – Part VI – Resource policies
Azure ARM templates and Visual Studio (older posts):
Azure Resource Manager–First Steps
Azure Resource Manager– Step 2–Copy and Public IPs
Hope this helps!
