Using Amazon RDS Recommendations

Amazon RDS provides automated recommendations for database resources. These recommendations provide best practice guidance by analyzing DB instance configuration, usage, and performance data.

You can find examples of these recommendations in the following table.

Type Description Recommendation Additional Information

Engine version outdated

Your DB instance is not running the latest minor engine version.

We recommend that you upgrade to the latest version because it contains the latest security fixes and other improvements.

Upgrading a DB Instance Engine Version

Pending maintenance available

You have pending maintenance available on your DB instance.

We recommend that you perform the pending maintenance available on your DB instance. Updates to the operating system most often occur for security issues and should be done as soon as possible.

Maintaining a DB Instance

Automated backups disabled

Your DB instance has automated backups disabled.

We recommend that you enable automated backups on your DB instance. Automated backups enable point-in-time recovery of your DB instance. You receive backup storage up to the storage size of your DB instance at no additional charge.

Working With Backups

Magnetic volumes in use

Your DB instance is using magnetic storage.

Magnetic storage is not recommended for most DB instances. We recommend switching to General Purpose (SSD) storage or provisioned IOPS storage.

Amazon RDS DB Instance Storage

EC2-Classic platform in use

Your DB instance is using the legacy EC2-Classic platform.

We recommend moving your DB instance to the EC2-VPC platform for better network access control. Amazon VPC provides a virtual network that is logically isolated from other virtual networks in the AWS Cloud.

Determining Whether You Are Using the EC2-VPC or EC2-Classic Platform

Enhanced Monitoring disabled

Your DB instance doesn't have Enhanced Monitoring enabled.

We recommend enabling Enhanced Monitoring. Enhanced Monitoring provides real-time operating system metrics for monitoring and troubleshooting.

Enhanced Monitoring

Encryption disabled

Your DB instance doesn't have encryption enabled.

We recommend enabling encryption. You can encrypt your existing Amazon RDS DB instances by restoring from an encrypted snapshot.

Encrypting Amazon RDS Resources

Previous generation DB instance class in use

Your DB instance is running on a previous-generation DB instance class.

Previous-generation DB instance classes have been replaced by DB instance classes with better price, better performance, or both. We recommend running your DB instance on a later generation DB instance class.

Choosing the DB Instance Class

Amazon RDS generates recommendations periodically across all accounts and resources.

Responding to Amazon RDS Recommendations

You can find recommendations in the AWS Management Console. You can perform the recommended action immediately, schedule it for the next maintenance window, or dismiss it.

To respond to Amazon RDS recommendations

  1. Sign in to the AWS Management Console and open the Amazon RDS console at

  2. In the navigation pane, choose Recommendations.

                        Select Recommendations in the console

    The Recommendations page appears.

                        Main Recommendations page in the console
  3. On the Recommendations page, choose one of the following:

    • Active – Shows the current recommendations that you can apply, dismiss, or schedule.

    • Dismissed – Shows the recommendations that have been dismissed. When you choose Dismissed, you can apply these dismissed recommendations.

    • Applied – Shows the recommendations that are currently applied.

    • Scheduled – Shows the recommendations that are scheduled but not yet applied. These recommendations will be applied in the next scheduled maintenance window.

    From any list of recommendations, you can open a section to view the recommendations in that section.

                        Take action on recommendations in the console

    To configure preferences for displaying recommendations in each section, choose the Preferences icon.

                        Preferences icon for Recommendations in the console

    From the Preferences window that appears, you can set display options. These options include the visible columns and the number of recommendations to display on the page.

  4. Manage your active recommendations:

    1. Choose Active and open one or more sections to view the recommendations in them.

    2. Choose one or more recommendations and choose Apply now (to apply them immediately), Apply in next maintenance window, or Dismiss.

      If the Apply now button appears for a recommendation but is unavailable (grayed out), the DB instance is not available. You can apply recommendations immediately only if the DB instance status is available. For example, you can't apply recommendations immediately to the DB instance if its status is modifying. In this case, wait for the DB instance to be available and apply the recommendation.

      If the Active button doesn't appear for a recommendation, you can't apply the recommendation using the Recommendations page. You can modify the DB instance to apply the recommendation manually. For more information about modifying a DB instance, see Modifying an Amazon RDS DB Instance.


      When you choose Apply now, a brief DB instance outage might result.
