Azure Files Sync

1. Create Azure File Sync
2. Create a strorage account
   1. Create a new Files Shares
3. Create a Sync Group
   1. Link the group to the just created file shares
4. Connect to a window VM
   1. Download the: File Sync Agent
   2. Connect to the Azure File Sync from the agent
5. From the Azure File Sync
   1. registered servers: VMs connected
   2. Add one or more server endpoint: folder to be sync in a specific vm
   3. Ideally one server endpoint for each vm/folder
6. Now the files created acrosss the different VMs are synchronized

In a Sync Group, you can have only one cloud endpoint (file share) :bangbang:
