Amazon launches new database service

“Many developers simply want to store, process, and query their data without worrying about managing schemas, maintaining indexes, tuning performance or scaling access to their data,” the documentation explains. “Amazon SimpleDB removes the need to maintain a schema, while your attributes are automatically indexed to provide fast real-time lookup and querying capabilities.”

SimpleDB costs 14 cents per machine hour, with no minimum fee. This is normalized to the hourly capacity of a 2007 1.7 GHz Xeon processor. There’s also a data transfer charge of 10 cents per Gbyte transferred in. For data transferred out, the rate starts at 18 cents per Gbyte for first 10 Tbytes per month, then drops to 16 cents for the next 40 Tbytes per month, and finally drops to 13 cents per Gbyte for 50 Tbytes and beyond per month. These fees apply to data transferred in and out of Amazon SimpleDB. Data transferred between SimpleDB and other Amazon Web services is moved without additional cost. There’s also a $1.50 fee per Gbyte per month for the storage of structured data.

There’s one significant cost that SimpleDB users can avoid: keeping a database administrator on the payroll.
