Enable DynamoDB Table Auto Scaling Rule

DynamoDB Table Auto Scaling Rule for NIST 800-53 Revision 5

Rule Description:

Troubleshooting Steps:

2. 1.

   Verify IAM Permissions: Ensure that the AWS Identity and Access Management (IAM) user or role used for managing the DynamoDB table has the necessary permissions to enable auto scaling. They should have the

   dynamodb:UpdateTable

   permission.

4. 2.

   Check Table Status: Confirm that the table is active and not in the process of being created, deleted, or modified. Auto scaling cannot be enabled during these operations.

6. 3.

   Verify AWS Region: Ensure that you are checking and modifying the correct DynamoDB table in the desired AWS region. Auto scaling settings are region-specific.

Step-by-Step Guide for Enabling DynamoDB Table Auto Scaling:

2. 1.

   AWS Management Console:

   • Log in to the AWS Management Console.
   • Navigate to the DynamoDB service.
   • Select the desired region.
   • Click on the specific table you want to enable auto scaling for.
4. 2.

   AWS CLI:

   • Install and configure the AWS CLI if you haven't already done so.
6. 3.

   AWS Management Console:

   • In the Table details view, click on the "Capacity" tab.
   • Scroll down to the "Auto Scaling" section and click on the "Manage capacity" button.
8. 4.

   AWS CLI:

   • Open your preferred terminal or command prompt.
10. 5.

    AWS Management Console:

    • In the "Manage capacity" window, select the "Auto scaling" tab.
12. 6.

    AWS CLI:

    • Run the following command to enable auto scaling:

      aws dynamodb update-table --table-name <table-name> --provisioned-throughput AutoScalingSettings="{MinimumUnits=<min-capacity>,MaximumUnits=<max-capacity>,SeedCapacity=<seed-capacity>,TargetScalingPolicy="<scaling-policy>"}"
      

    • Replace

      <table-name>

      with the name of your DynamoDB table.

    • Set

      <min-capacity>

      to the minimum provisioned capacity required for auto scaling.

    • Set

      <max-capacity>

      to the maximum provisioned capacity allowed for auto scaling.

    • Set

      <seed-capacity>

      to the number of read capacity units (RCUs) or write capacity units (WCUs) that are provisioned initially.

    • Choose a suitable

      <scaling-policy>

      based on your application requirements.
14. 7.

    AWS Management Console:

    • Adjust the settings for minimum and maximum capacity, as well as the target scaling policy according to your desired configurations.
    • Save the changes.
