I'm trying to more or less create the cheapest VM I can create, so I was wondering a few things:
What's the cheapest disk type to use?
Is there a way to set the size of a disk to only the size required for the image I choose? (how do I get this size?) (in this case, the image I'm using is Ubuntu Server)
If I decide to destroy my existing VM, is there any penalty? Can I use the same names? Can I use the same DNS subdomain (<subdomain>.<region>.cloudapp.microsoft...), or do I have to pick another one? Is it as simple as just deleting it, or are there other things left over?
Are there any other things I can do, besides choosing the smallest VM size (Standard B1ls), using the cheapest disk type and smallest disk size, and only keeping the VM on when I'm using it (which is maybe an hour a week), to reduce the cost even more?
