DynamoDB tables should automatically scale capacity with demand

Severity: Medium

Resource Types: AWS::DynamoDB::Table

Description​

This control checks whether an Amazon DynamoDB table can scale its read and write capacity as needed. This control passes if the table uses either on-demand capacity mode or provisioned mode with auto scaling configured. Scaling capacity with demand avoids throttling exceptions, which helps to maintain availability of your applications.

DynamoDB tables in on-demand capacity mode are only limited by the DynamoDB throughput default table quotas. To raise these quotas, you can file a support ticket through AWS Support.

DynamoDB tables in provisioned mode with auto scaling adjust the provisioned throughput capacity dynamically in response to traffic patterns.
