The database I am using is 10 dollars a month, but obviously no one can get a database to server a huge number of customers for ten dollars.
SQL Azure throttles your use if you use long-running queries or otherwise hog resources. Otherwise, you get a 1GB database for $10 as the ad says.
Is the "ConnectionPacks" the way that this is calculated?
Connection Packs are used with Azure AppFabric Service Bus and have nothing to do with SQL Azure.
