Virtual Machine Expenses

Question

This is my first time making Azure Virtual Machine, so I'd like to ask a few things about it.
Say in 1 subscription I made 3 Virtual Machines, which run on Windows Server 2012 R2 Datacenter.
I made it with Azure spot discount, which charges me hourly.
Yet, the first day passed and I saw there were extra expenses from "Storage".

Now the question is, is it possible to, say, use 1 "Storage" for those 3 Virtual Machines for example?
Or is there any way to reduce my bills from this so-called storage?

Answer 1

All VMs will incur storage costs regardless of whether or not the VM is on. The main things to minimize storage costs revolve around keeping the VM disk as small as possible, and to use Locally Redundant Storage (LRS) instead of GRS, and HDD vs SSD. Obviously, there's tradeoffs in performance and redundancy using those SKUs.
