At http://aws.amazon.com/free/, the documentation indicates the Free Usage Tier comes with 30 GB of Amazon Elastic Block Storage, and for database/RDS, 20 GB of database storage.
When I create launch a new database SQL Server Express instance with the AWS Toolkit for Visual Studio 2010, the minimum allocated storage available is 30gb. Is this an undocumented feature, as I believe creating the instance through another interface shows 20gb?
From this I gather that each database on this instance will be limited to 10GB (SS Express).
I have created a Windows Server/IIS instance which leaves about 7 gigs of EBS left on that box.
Does this mean I still have 30gb available for my databases on the db engine instance (separate db server)?
If a database size reaches/exceeds 10gb, will AWS/RDS automatically scale my account up to the next SQL Server version? If so, how can I avoid this?
