Hello all,
I've got a quick question about how Azure storage is calculated and how that effects the pricing.
I'm planning to migrate around 100 VM's to Azure IaaS, on average a server will contain an OS disk and at least 1 or 2 data disks. I'll be using a regular, locally redundant storage account (no geo replication, no premium storage).
Seeing the complexity of resizing disks of Azure VM's (deallocate VM, remove VM configuration, download disk, extend disk with xx GB's, upload disk, create VM configuration, start VM) wer're considering to increase the disks of our on-premise VM's to the max allowed capacity for an Azure VM (OS disk 127GB, datadisks 1024GB).
However, doing this would leave a lot of free space on the disks. If I extend a datadisk to 1024 GB and in practice I only put 24GB of actual data on the disk (leaving me with 1000GB empty space), would I be billed for 1024 GB (actual disk size) or 24 GB (actual amount of data on the disk).
I found the following statement in the Azure Storage FAQ:
"If the empty 100GB disk is backed by a Premium Storage Account then you will be charged for a P0 (128GB) disk. If any other type of Storage Account is used then youll only be billed for the storage space used to store the data that is written to the disk regardless of the allocated disk size."
After reading I'm tempted to think I would only be charged for the 24 GB but some (more clear) information would be appreciated.
Cheers
