Using Blob as a Network Share

Hi,

I have two perpetual virtual machines in an availability set. At any time only 1 of these will be in use but if the second machine became active (during a failure/patching in the 'first'  machine) then any data created by the 'first' machine should be readily available to the 'second' machine.

In the real world we would use a network share and/or a mapped drive but in Azure I do not believe this is possible without using yet another VM instance and an Azure Virtual Network (which I am not willing to use at this time).

How can I create a blob storage container which acts as a share and can be accessed by more than 1 VM instance which would addressable as a share or mapped drive?

Thanks
