Amazon SimpleDB Description
Amazon SimpleDB is a high-availability NoSQL data store that offloads database administration. Developers can simply store and query data items using web services requests, and Amazon SimpleDB takes care of the rest. Amazon SimpleDB is not bound by the requirements of a relational data base. It is optimized to provide high availability, flexibility and minimal administrative burden. Amazon SimpleDB automatically creates and manages multiple copies of your data in different locations to ensure high availability and data durability. You only pay for the actual resources used to store your data and serve your requests. You can modify your data model at any time, and data is automatically index for you. Amazon SimpleDB allows you to focus on application development and not worry about infrastructure provisioning, high availability or software maintenance.
