Amazon DynamoDB
Developer Guide (API Version 2012-08-10)

Summary

In this tutorial, you created the Movies table in DynamoDB on your computer and performed basic operations. The downloadable version of DynamoDB is useful during application development and testing. However, when you're ready to run your application in a production environment, you must modify your code so that it uses the Amazon DynamoDB web service.

Updating the AWS Configuration Region to Use the DynamoDB Web Service

To use the DynamoDB web service, you must update the Region in your application. You also have to make sure that Amazon Cognito is available in that same Region so that your browser scripts can authenticate successfully.

Copy
AWS.config.update({region: "aws-region"});

For example, if you want to use the us-west-2 region, set the following region:

Copy
AWS.config.update({region: "us-west-2"});

The program now uses the Amazon DynamoDB web service region in US West (Oregon).

DynamoDB is available in several regions worldwide. For the complete list, see Regions and Endpoints in the AWS General Reference. For more information about setting regions and endpoints in your code, see Setting the Region in the AWS SDK for JavaScript Getting Started Guide.

Configuring AWS Credentials in Your Files Using Amazon Cognito

The recommended way to obtain AWS credentials for your web and mobile applications is to use Amazon Cognito. Amazon Cognito helps you avoid hardcoding your AWS credentials on your files. Amazon Cognito uses AWS Identity and Access Management (IAM) roles to generate temporary credentials for your application's authenticated and unauthenticated users.
