Summary - Amazon DynamoDB


In this tutorial, you created the Movies table in the downloadable version of Amazon 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 DynamoDB web service.

Modifying the Code to Use the DynamoDB Service

To use the DynamoDB service, you must change the endpoint in your application. To do this, find the following lines in the code.

Aws.config.update({ region: "us-west-2", endpoint: "http://localhost:8000" })

Remove the endpoint parameter so that the code looks like the following.

Aws.config.update({ region: "us-west-2" ]);

After you remove this line, the code can access the DynamoDB service in the AWS Region specified by the region config value.

Instead of using the version of DynamoDB on your computer, the program uses the DynamoDB web service endpoint in the US West (Oregon) Region.

DynamoDB is available in AWS Regions worldwide. For the complete list, see Regions and Endpoints in the AWS General Reference. For more information, see the AWS SDK for Ruby Getting Started Guide.
