A non-relational database cloud service that can be used to store and query data items via web services requests through Amazon Web Services (AWS). Amazon SimpleDB frees companies from the administrative tasks of maintaining databases while providing high availability and flexibility to its customers.
As its name implies, Amazon SimpleDB is suited more for less complex database environments where users need to quickly look up and access data in non-relational databases. As with other Amazon AWS services, Amazon SimpleDB customers are charged based on the resources used to store their SimpleDB data and the requests made to access that data.
Amazon SimpleDB complements other services offered through Amazon Web Services, including Amazon Simple Storage Service (Amazon S3), which handles storing files in the cloud, and Amazon Elastic Compute Cloud (Amazon EC2), which provides customers the ability to run a variety of database servers in situations where the database s complexity is more than Amazon’s SimpleDB service is designed to handle.
