Managing Recommendations

Commander generates some recommendations and retrieves others from AWS to help you optimize VM performance and minimize cost. The following types of recommendations are available:

To view all recommendations, go to Tools > Recommendations.

About cloud expense management

To benefit most from Commander's cloud expense management, carry out these steps in the following order:

  1. Apply rightsizing recommendations.
  2. Configure and apply power schedule recommendations.
  3. For AWS, use Reserved Instance recommendations or the Reserved Instance Recommendations Report to guide your RI purchases.

    Note: If you begin by purchasing RIs, you may end up purchasing the wrong size or quantity of RIs, which can be an expensive mistake.

  4. Monitor and repeat.

Cost optimization is an ongoing, iterative process. Once you've rightsized, set power schedules and purchased RIs, it's critical to monitor your cloud platform infrastructure and your bill, and continually optimize.

Watch our Cloud Cost Optimization video to learn about the features that work together to reduce your cloud costs.

Rightsizing recommendations

Commander generates rightsizing recommendations for VMs based on data retrieved from cloud accounts (and optionally from third-party performance monitoring tools).

On the Recommendations page, to view only memory rightsizing recommendations, enter "memory" in the search field. To view only instance type rightsizing recommendations, enter "instance type" in the search field. To view only downsizing recommendations, enter "down" in the search field. You may have to click Show Quick Search to hide the filter.

To customize the rules used to generate rightsizing recommendations, go to Configuration > Groups > Rightsizing.

For more information, see Rightsizing VMs and Instances and Configuring Rules for VM Rightsizing.

Power schedule recommendations

Power schedule groups help to ensure that VMs are powered on when needed and powered off when not needed, to minimize cost without hindering productivity. Commander issues power schedule recommendations for VMs.

On the Recommendations page, to view only power schedule recommendations, enter "power" in the search field. You may have to click Show Quick Search to hide the filter.

To customize the rules used to generate power schedule recommendations, go to Configuration > Groups > Power Schedule, and click Configure Recommendations.

For more information, see Configuring and Applying Power Schedule Recommendations.

Reserved Instance recommendations

Commander retrieves recommendations to purchase EC2 RIs from AWS. Purchasing RIs provides a significant discount compared with paying for on-demand pricing. Based on your EC2 instance uptime, Commander retrieves and displays potential EC2 RI purchases for each region and shows you the projected savings for each purchase, based on regions.

Note: There's a fee of $0.01 USD per request to AWS to retrieve recommendation data. Generally, only one request is required per consolidated billing account. For cloud accounts with many resources, multiple requests may be required. These request fees will be visible on the Cost Dashboard.

On the Recommendations page, to view only RI recommendations, enter "reserved" in the search field. You may have to click Show Quick Search to hide the filter.

To customize the rules used to retrieve RI recommendations:

  1. Go to Configuration > Costs

  2. Navigate to the RI Recommendation Configuration tab
