where it says it won't charge if the data warehouse is paused but in my case it charged me after I paused the
Data Warehouse. It charged me for DWU. Is there something am I missing ?
I want to know different angles of billing on Microsoft Azure SQL Data Warehouse.
Also my account is a Free Trial. How can I see price paid for different resources on Portal. I tried it by clicking on Billing one of the option provided in portal but it does not show much information.
One more question is I have my DWU location in West US which costs ₹100/hour
which is more than West Central US which costs ₹80/hour for 100 DWU Blocks, so is there any difference between those two Services or it is just about Distance ?
I'm going to try to answer your questions in sequence:
Q1: Why was I billed for DWU even though you paused your DW?
A1: DWU are charged prorated on an hourly basis. You can see this in How are compute and data storage billed? section of the document that you referenced. So even if you pause, you will be charged for at least an hour.
Q2: How could I be charged with a free trial account?
