Provisioned Database Storage
For each DB Instance class, Amazon RDS provides you the ability to select from 5 GB to 1 TB of associated storage capacity for your primary data set.

Data transferred between two Amazon Web Services within the same region (e.g. between Amazon RDS US and Amazon EC2 US) is free of charge.
The minimum on Amazon is 5GB, so let's compare 10GB. For Amazon at 1 month, you're paying $0.10 * 10 = $1 for storage and your $81.84 is about right. Note that this $82.84 is not comparable to the "Web Edition" offering from Microsoft, as that's for 1GB of storage. The "Small DB Instance" offering from Amazon is for an instance, not for storage, which you pay for completely separately.
So this $82.84 figure is really only comparable to Microsoft's "Business Edition" offering at $99.99, both before bandwidth costs. Bandwidth costs apply to Azure too under a different pricing model. The data in cost is exactly the same and the data out cost is $0.02/GB more expensive for Amazon for the first 10 TB and cheaper after that. You do have to pay Amazon an additional $0.10 per 1 million I/O requests, though.
On the other hand, Amazon allows you to buy way more than 10GB of storage, different instances, and did I mention they were using MySQL?

SQL Azure Database supports Transact-SQL (T-SQL). Customers can use existing knowledge in T-SQL development and a familiar relational data model for symmetry with existing on-premises databases. SQL Azure Database can help reduce costs by integrating with existing toolsets and providing symmetry with on-premises and cloud databases.
