Confused about Azure VM Creation
===

So I am a little bit confused about the Azure feature to create virtual machines(i.e VMRoles).

When I do a quick create via the managment portal, I am not asked to specify nor a hosted service nor a storage account. After I click 'create' I see that a storage account is generated for me automatically with some unique name, but I don't see the same for a hosted service. Is a hosted service not needed to create a VM? 

The thing that is confusing is that it seems like every other method for creating a VM does require me to specify a hosted service (Azure PowerShell, REST API). And indeed after I create the VM using one of these methods I see my VM inside the hosted service...

Anyone can explain this? 

Thanks in advance
