Recommendations for Making Secure Requests
Our recommendations for making secure requests are:
- Always use SSL-protected API endpoints. For SOAP requests, using SSL will soon be required.
- If you are not using SOAP, we have introduced a new method for signing requests for Amazon SQS, Amazon SimpleDB, and Amazon EC2, called Signature Version 2. All non-SOAP requests will soon be required to use this new method.
To help protect our customer’s applications, and to ensure that you have sufficient time to adapt your applications, our APIs will continue to accept SOAP requests over HTTP and REST requests using previous signature versions until September 30, 2009. However, we recommend that you migrate your application as soon as possible.
Please see the article Making Secure Requests to Amazon Web Services for more information about these recommendations and how to migrate your application.

| 100 attributes limit in PutAttributes call | Amazon SimpleDB currently limits the number of attributes per single PutAttributes call to 100. You can add up to 256 attribute name-value pairs per item, but you must use multiple PutAttributes calls. |
