Cost optimization

Checks your Amazon Elastic Compute Cloud (Amazon EC2) instances that are running SQL Server in the past 24 hours. An SQL Server database has a compute capacity limit for each instance. An instance with SQL Server Standard edition can use up to 48 vCPUs. An instance with SQL Server Web can use up to 32 vCPUs. This check alerts you if an instance exceeds this vCPU limit.

If your instance is over-provisioned, you pay full price without realizing an improvement in performance. You can manage the number and size of your instances to help lower costs.

Estimated monthly savings are calculated by using the same instance family with the maximum number of vCPUs that an SQL Server instance can use and the On-Demand pricing. Actual savings will vary if you’re using Reserved Instances (RI) or if the instance isn’t running for a full day.

For SQL Server Standard edition, consider changing to an instance in the same instance family with 48 vCPUs. For SQL Server Web edition, consider changing to an instance in the same instance family with 32 vCPUs. If it is memory intensive, consider changing to memory optimized R5 instances. For more information, see Best Practices for Deploying Microsoft SQL Server on Amazon EC2.

Checks if there are Amazon EC2 instances that have been stopped for more than 30 days.

You can specify the allowed number of days value in the AllowedDays of Amazon Config parameters.

For more information, see Why am I being charged for Amazon EC2 when all my instances were terminated?

AWS Config Managed Rule: ec2-stopped-instance

Review the Amazon EC2 instances that have been stopped for 30 days or more. To avoid incuring unnecessary costs, terminate any instances that are no longer needed.

For more information, see Terminate your instance.

Checks that each Amazon S3 bucket is configured with a lifecycle rule to abort multipart uploads that remain incomplete after 7 days. Using a lifecycle rule to abort these incomplete uploads and delete the associated storage is recommended.

Yellow: The lifecycle configuration bucket does not contain a lifecycle rule to abort all multipart uploads that remain incomplete after 7 days.

Review lifecycle configuration for buckets without a lifecycle rule that would cleanup all incomplete multipart uploads. Uploads that are not completed after 24 hours are unlikely to be completed. Click here to follow instructions to create a lifecycle rule. It is recommended that this is applied to all objects in your bucket. If you have a need to apply other lifecycle actions to selected objects in your bucket, you can have multiple rules with different filters. Check the storage lens dashboard or call the ListMultipartUpload API for more information.

Checks your Elastic Load Balancing configuration for load balancers that are idle.

Any load balancer that is configured accrues charges. If a load balancer has no associated back-end instances, or if network traffic is severely limited, the load balancer is not being used effectively. This check currently only checks for Classic Load Balancer type within ELB service. It does not include other ELB types (Application Load Balancer, Network Load Balancer).

If your load balancer has no active back-end instances, consider registering instances or deleting your load balancer. See Registering Your Amazon EC2 Instances with Your Load Balancer or Delete Your Load Balancer.

If your load balancer has no healthy back-end instances, see Troubleshooting Elastic Load Balancing: Health Check Configuration.

If your load balancer has had a low request count, consider deleting your load balancer. See Delete Your Load Balancer.

Checks for Elastic IP addresses (EIPs) that are not associated with a running Amazon Elastic Compute Cloud (Amazon EC2) instance.

EIPs are static IP addresses designed for dynamic cloud computing. Unlike traditional static IP addresses, EIPs mask the failure of an instance or Availability Zone by remapping a public IP address to another instance in your account. A nominal charge is imposed for an EIP that is not associated with a running instance.

Yellow: An allocated Elastic IP address (EIP) is not associated with a running Amazon EC2 instance.

Associate the EIP with a running active instance, or release the unassociated EIP. For more information, see Associating an Elastic IP Address with a Different Running Instance and Releasing an Elastic IP Address.
