Setting your rightsizing recommendation preferences

This section provides you with instructions on how to set your rightsizing recommendation preferences in AWS Compute Optimizer.

Procedure

Step 1: Set preference level (Organizations only)

If you're the account manager or the delegated administrator of your organization, you can choose all the accounts in an organization or specific accounts to which you want to apply rightsizing recommendation preferences.

Note

If you’re an individual AWS account holder, skip to Step2: Regional scope.

To set the preference level for your rightsizing recommendation preferences

1. Open the Compute Optimizer console at https://console.aws.amazon.com/compute-optimizer/.

2. Choose Rightsizing in the navigation pane.

3. Choose the resource type you want from the Resource type dropdown menu.

4. In your chosen resource section, choose the All opted-in accounts dropdown menu.

   • To opt in all member accounts, choose All opted-in accounts from the Preference level dropdown.

   • To opt in an individual member account, choose Choose account from the Preference level dropdown. In the prompt that appears, select the account you want to opt in for rightsizing preferences. Then, choose Set account level.

   

Step 2: Set regional scope

In this step you can specify the AWS Regions where you want Compute Optimizer to apply your rightsizing recommendation preferences. For example, if you select the US East (N. Virginia) Region and US East (Ohio) Region, we only apply the preferences to those Regions.

To set the regional scope of your rightsizing recommendation preferences

1. Open the Compute Optimizer console at https://console.aws.amazon.com/compute-optimizer/.

2. Choose Rightsizing in the navigation pane.

3. Choose the resource type you want from the Resource type dropdown menu.

4. On the Rightsizing preferences page, choose Edit.

5. Choose either Any Region or Custom Regions based on your requirements.

6. If you choose Custom Regions, select the AWS Regions where you want Compute Optimizer to apply your preferences. Then, choose Next.

   

Step 3: Specify preferred EC2 instances

Use the following procedure to specify your preferred instance types and sizes for member accounts of an organization or an individual AWS account holder.

To set the instances you want in your recommendation output

1. Follow the steps outlined in Step2: Regional scope.

2. On the Preferred EC2 instances page, choose either Any instance type (default) or Limit to specific instance types and sizes based on your requirements.

3. If you choose Limit to specific instance types and sizes, select the instance types you want in your recommendation output.

   • Use the Search by instance families dropdown menu. When you select any of the instance families, the list only displays the available instance types within those families that you selected.

   • Use the Find instance types search bar to enter the specific instance types you want.

   

4. (Optional) To specify the sizes of each instance type, do the following:

   1. Choose the edit icon on the instance type you want.

   2. Select X on the instance sizes that you don’t want.

   3. Select ✔ to confirm your selections.

5. (Optional) If you don't want Compute Optimizer to automatically consider future variations of your chosen instance families, turn off Automatically consider future variations of the instance families selected.

   

6. Choose Next.

Step 4: Specify lookback period and metrics

Use the following procedure to specify the lookback period, and the CPU and memory utilization preferences you want Compute Optimizer to use when generating your custom recommendations.

To set the lookback period, and CPU and memory preferences

1. Follow the steps outlined in Step 4: Preferred EC2 instances.

2. On the Lookback period and metrics page, choose a lookback period option based on your requirements.

   • If you want to use the 93-day lookback period (paid feature), you need to enable the enhanced infrastructure metrics preference. To do this, choose Enable enhanced infrastructure metrics. Then, in the prompt that appears, choose Enable enhanced infrastructure metrics.

   • If the enhanced infrastructure metrics preference is already enabled and you want to choose a 14-day or 32-day lookback period, you need to disable the enhanced infrastructure metrics preference. To do this, choose Disable enhanced infrastructure metrics. Then, in the prompt that appears, choose Disable enhanced infrastructure metrics.

3. Choose a utilization preset: Max savings, Balanced, Default, or Max performance.

   Alternatively, you can customize your own specific CPU and memory utilization preferences.

   

4. Choose Next.

5. On the Review and save page, review all the preferences you have set. Then, choose Save preferences.

Within 24 hours your new recommendations start to appear with the rightsizing preferences that you set.
