So far, I was under the impression that
- you rent an Azure VM for the processing power, the RAM and the OS license and then
- you add BLOB storage for whatever your storage needs are.
However, when looking at the Azure VM pricing page, I see that the instances include a column "disk size", e.g.
A0 1 core 0.75 GB RAM 20 GB Disk Size EUR 11.29/mo A1 1 core 1.75 GB RAM 40 GB Disk Size EUR 25.10/mo ...
If Azure storage is billed on a per-use basis, what is the relevance of those "disk sizes"? Is it some "extra included" storage at no additional cost? Or is it a limit of how much storage you can add?
