I would echo the previous posters . . . this pricing model is nuts.
One of the big pluses of Azure is very fast provisioning of micro-developments to respond to specific business needs right now. Part of doing that is to provision a reports server quickly, even knowing it won't get used very much.
The pricing model for Azure SQL Database is brilliant . . . I can create a little SQL Database and upload it via SSDT the same day. (Haven't got a good fast solution for online data entry yet, though, any ideas?)
But the Reporting guys have gone squirrely! The pricing model of $/provisioned hour kills the whole concept of Azure SQL Reporting from little systems stone-dead.
