Amazon Simple Database Service (SimpleDB)

Amazon Simple Database Service (SimpleDB), also known as a key value data store, is a highly available and flexible non-relational database that allows developers to request and store data, with minimal database management and administrative responsibility.

This service offers simplified access to a data store and query functions that let users instantly add data and effortlessly recover or edit that data. SimpleDB is best used by customers who have a relatively simple data requirement, like data storage. For example, a business might use cookies to track visitors that visit its company website. The business might read the cookies to get the visitor’s identifier and look up which feeds they’re interested in. Amazon SimpleDB gives users the option to store tens of attributes for a million customers, but not thousands of attributes for a single customer.

SimpleDB provides a URL endpoint to guarantee encrypted messages between an application and a domain. In conjunction with AWS Identity and Access Management, you can create permissions for groups and users to specific SimpleDB domains. Amazon SimpleDB works with other Amazon services to give developers the ability to store their data in Amazon Simple Queue Service and run their applications in Amazon Elastic Compute Cloud.

Because Amazon SimpleDB provides scaling, customers only pay for resources used and not for compute resources when they aren’t actively being used.
