Amazon SimpleDB TM (beta)
Amazon SimpleDB is a highly available, scalable, and flexible non-relational data store that offloads the work of database administration. Developers simply store and query data items via web services requests, and Amazon SimpleDB does the rest.
Unbound by the strict requirements of a relational database, Amazon SimpleDB is optimized to provide high availability, ease of scalability, and flexibility with little or no administrative burden. Behind the scenes, Amazon SimpleDB creates and manages multiple geographically distributed replicas of your data automatically to enable high availability and data durability. The service responds to changes in traffic by charging you only for the compute and storage resources actually consumed in serving your requests. You can change your data model on the fly, and data is automatically indexed for you. With Amazon SimpleDB, you can focus on application development without worrying about infrastructure provisioning, high availability, software maintenance, schema and index management, or performance tuning.

Pricing
You can get started with SimpleDB for free. Amazon SimpleDB users pay no charges on the first 25 Machine Hours, 1 GB of Storage, and 1 GB of Data Transfer Out consumed every month. Under the new free inbound data transfer promotion, all data transfer into Amazon SimpleDB is free of charge until June 30, 2010. In most use cases, the free tier enables approximately 2,000,000 GET or SELECT API requests to be completed per month before incurring any usage charges. Many applications should be able to operate perpetually within this free tier, such as a daily website analysis and traffic reporting tool, a web indexing service, or an analytics utility for online marketing programs.
As your demand grows, you still pay only for what you use. As with other AWS services, there is no minimum fee and no long-term commitment. Also, note that we charge less where our costs are less, thus some prices vary across Geographic Regions. The prices listed are based on the Region in which you establish your Amazon SimpleDB domain(s). Amazon SimpleDB may be used from most countries, so long as payment is made in US Dollars.
Machine Utilization
Amazon SimpleDB measures the machine utilization of each request and charges based on the amount of machine capacity used to complete the particular request (SELECT, GET, PUT, etc.), normalized to the hourly capacity of a circa 2007 1.7 GHz Xeon processor. See below for a more detailed description of how machine utilization charges are calculated.See below for a more detailed description of how machine utilization charges are calculated.
Data Transfer
- Data Transfer In is free until June 30, 2010
*
- First 1 GB of data transferred out per month is free; thereafter:
- $0.15 per GB – first 10 TB / month data transfer out
- $0.11 per GB – next 40 TB / month data transfer out
- $0.09 per GB – next 100 TB / month data transfer out
- $0.08 per GB – data transfer out / month over 150 TB
* Data Transfer In will be $.10 per GB after June 30, 2010Data transfer “in” and “out” refers to transfer into and out of Amazon SimpleDB. There is no additional charge for data transferred between Amazon SimpleDB and other Amazon Web Services within the same Region (i.e., $0.00 per GB). Data transferred across Regions (e.g., between Amazon SimpleDB in the EU (Ireland) Region and Amazon EC2 in the US-East (Northern Virginia) Region, will be charged at Internet Data Transfer rates on both sides of the transfer.
Structured Data Storage
Amazon SimpleDB measures the size of your billable data by adding the raw byte size of the data you upload + 45 bytes of overhead for each item, attribute name and attribute-value pair.
Amazon SimpleDB is designed to store relatively small amounts of data and is optimized for fast data access and flexibility in how that data is expressed. In order to minimize your costs across AWS services, large objects or files should be stored in Amazon S3, while the pointers and the meta-data associated with those files can be stored in Amazon SimpleDB. This will allow you to quickly search for and access your files, while minimizing overall storage costs. See below for a detailed explanation of how storage in Amazon SimpleDB and storage in Amazon S3 differ and a more detailed description on calculating your Storage Costs.
* The free tier is a monthly offer. Free usage does not accumulate.
** Any data stored as part of the free tier program must be actively used. If a domain is not accessed for a period of 6 months, it will be subject to removal at the discretion of Amazon Web Services.
