Cloud Cost Recommendations

Cloud Cost Management is not supported for this site.

Join the Beta!

Cloud Cost Recommendations is in public beta with support for AWS, and is automatically enabled if you have set up Cloud Cost Management.


Cloud Cost Recommendations provide recommendations on reducing your cloud spending by optimizing the usage of your cloud resources.

Overview tab with potential monthly savings, potential annual savings, and total number of open cases on the Cloud Cost Recommendations page

Recommendations combine billing data and observability data to identify orphaned, legacy, or over-provisioned cloud resources.


For each AWS account that you would like to receive recommendations for:

  1. Configure Cloud Cost Management to send bill data to Datadog.
  2. Enable resource collection in the Resource Collection tab on the AWS integration tile.
  3. Install the Datadog Agent (required for over-provisioned resource recommendations).

Recommendation types

Datadog generates a set of recommendations by combining your observability data with your underlying cloud provider’s billing data. You can see the detailed logic for each recommendation type, along with observability metrics or cost data used to generate the recommendation, on the Recommendations page.

Recommendations are run on a daily basis, and are automatically refreshed in your account. When new recommendations are released, Datadog automatically adds them to your account.

Terminate resource recommendations

Datadog scans your cloud environment to identify and surface orphaned resources that can be removed.

Unused EC2 Instances
EC2 instances with less than 5% CPU utilization, and less than 10% memory utilization.
Unattached EBS Volumes
Volumes that have been detached from an EC2 instance.
Unused EBS Volumes
Volumes attached to a non-running EC2 instance.
Unused RDS Instances
RDS instances with 0 database connections and 0 replica lag.
Abandoned S3 Multipart Uploads
Incomplete multipart uploads (requires Storage Lens metrics).
Unused Redshift Cluster
Redshift cluster with 0 database connections.
Unused Elasticache Redis Cluster
Elasticache Redis Cluster with 0 cache hits and 0 replication bytes.
Unused MQ Broker
An MQ broker with 0 connections.
Old ECR Images
ECR Image bytes are older than 180 days.
OpenSearch Cluster
An OpenSearch cluster with 0 connections.
Unused Classic Elastic Load Balancers
Classic Elastic Load Balancer with no active connections that is not attached to an EC2 instance.
Unused Network Elastic Load Balancer
A network load balancer with 0 processed bytes.
Unused Application Load Balancer
An application load balancer with no traffic being processed.
Unused NAT Gateway
A NAT Gateway that has no bytes sent out.
Idle Elastic IP Address
Elastic IP addresses with idle charges in your AWS cost and usage report.

Migrate resource recommendations

Datadog surfaces resources that are running on legacy hardware, which you can consider upgrading to reduce your costs and improve the performance of your resources.

Legacy EC2 Instance
EC2 Instances that are previous generation, and can be upgraded to a newer instance type.
GP2 EBS Volumes
EBS volumes that are GP2 and can be upgraded to GP3 for cost reduction and performance improvement.
I01 EBS Volumes
EBS volumes that are I01 and can be upgraded to GP3 for cost reduction and performance improvement.

Rightsize resource recommendations

Datadog identifies individual resources that are under-utilized or over-provisioned, which you can consider adjusting the size and configuration to reduce your costs and improve the performance of your resources.

Downsize EC2 instances
EC2 instances not in an auto-scaling group, with less than 50% CPU and memory utilization.
Overprovisioned Kubernetes Containers
Containers with less than 30% CPU and memory utilization.
Overprovisioned EBS Volume Throughput
EBS Volumes where the amount of throughput exceeds what is being used.
Overprovisioned EBS Volume IOPS
EBS Volumes where the amount of IOPS exceeds what is being used.
