list
The ID of the Amazon Web Services account for which to return Auto Scaling group recommendations.
If your account is the management account of an organization, use this parameter to specify the member account for which you want to return Auto Scaling group recommendations.
Only one account ID can be specified per request.
(string) --
list
The Amazon Resource Name (ARN) of the Auto Scaling groups for which to return recommendations.
(string) --
string
The token to advance to the next page of Auto Scaling group recommendations.
integer
The maximum number of Auto Scaling group recommendations to return with a single request.
To retrieve the remaining results, make another request with the returned nextToken value.
list
An array of objects to specify a filter that returns a more specific list of Auto Scaling group recommendations.
(dict) --
Describes a filter that returns a more specific list of recommendations. Use this filter with the GetAutoScalingGroupRecommendations and GetEC2InstanceRecommendations actions.
You can use EBSFilter with the GetEBSVolumeRecommendations action, LambdaFunctionRecommendationFilter with the GetLambdaFunctionRecommendations action, and JobFilter with the DescribeRecommendationExportJobs action.
name (string) --
The name of the filter.
Specify Finding to return recommendations with a specific finding classification. For example, Underprovisioned .
Specify RecommendationSourceType to return recommendations of a specific resource type. For example, Ec2Instance .
Specify FindingReasonCodes to return recommendations with a specific finding reason code. For example, CPUUnderprovisioned .
Specify InferredWorkloadTypes to return recommendations of a specific inferred workload. For example, Redis .
You can filter your EC2 instance recommendations by tag:key and tag-key tags.
A tag:key is a key and value combination of a tag assigned to your recommendations. Use the tag key in the filter name and the tag value as the filter value. For example, to find all recommendations that have a tag with the key of Owner and the value of TeamA , specify tag:Owner for the filter name and TeamA for the filter value.
A tag-key is the key of a tag assigned to your recommendations. Use this filter to find all of your recommendations that have a tag with a specific key. This doesn’t consider the tag value. For example, you can find your recommendations with a tag key value of Owner or without any tag keys assigned.
values (list) --
The value of the filter.
The valid values for this parameter are as follows, depending on what you specify for the name parameter and the resource type that you wish to filter results for:
Specify Optimized or NotOptimized if you specify the name parameter as Finding and you want to filter results for Auto Scaling groups.
Specify Underprovisioned , Overprovisioned , or Optimized if you specify the name parameter as Finding and you want to filter results for EC2 instances.
Specify Ec2Instance or AutoScalingGroup if you specify the name parameter as RecommendationSourceType .
Specify one of the following options if you specify the name parameter as FindingReasonCodes :
CPUOverprovisioned — The instance’s CPU configuration can be sized down while still meeting the performance requirements of your workload.
CPUUnderprovisioned — The instance’s CPU configuration doesn't meet the performance requirements of your workload and there is an alternative instance type that provides better CPU performance.

integer
The maximum number of instance recommendations to return with a single request.
To retrieve the remaining results, make another request with the returned nextToken value.
list
An array of objects to specify a filter that returns a more specific list of instance recommendations.
(dict) --
Describes a filter that returns a more specific list of recommendations. Use this filter with the GetAutoScalingGroupRecommendations and GetEC2InstanceRecommendations actions.
You can use EBSFilter with the GetEBSVolumeRecommendations action, LambdaFunctionRecommendationFilter with the GetLambdaFunctionRecommendations action, and JobFilter with the DescribeRecommendationExportJobs action.
name (string) --
The name of the filter.
Specify Finding to return recommendations with a specific finding classification. For example, Underprovisioned .
Specify RecommendationSourceType to return recommendations of a specific resource type. For example, Ec2Instance .
Specify FindingReasonCodes to return recommendations with a specific finding reason code. For example, CPUUnderprovisioned .

platformDifferences (list) --
Describes the configuration differences between the current instance and the recommended instance type. You should consider the configuration differences before migrating your workloads from the current instance to the recommended instance type. The Change the instance type guide for Linux and Change the instance type guide for Windows provide general guidance for getting started with an instance migration.
Platform differences include:
Hypervisor — The hypervisor of the recommended instance type is different than that of the current instance. For example, the recommended instance type uses a Nitro hypervisor and the current instance uses a Xen hypervisor. The differences that you should consider between these hypervisors are covered in the Nitro Hypervisor section of the Amazon EC2 frequently asked questions. For more information, see Instances built on the Nitro System in the Amazon EC2 User Guide for Linux , or Instances built on the Nitro System in the Amazon EC2 User Guide for Windows .
NetworkInterface — The network interface of the recommended instance type is different than that of the current instance. For example, the recommended instance type supports enhanced networking and the current instance might not. To enable enhanced networking for the recommended instance type, you must install the Elastic Network Adapter (ENA) driver or the Intel 82599 Virtual Function driver. For more information, see Networking and storage features and Enhanced networking on Linux in the Amazon EC2 User Guide for Linux , or Networking and storage features and Enhanced networking on Windows in the Amazon EC2 User Guide for Windows .
StorageInterface — The storage interface of the recommended instance type is different than that of the current instance. For example, the recommended instance type uses an NVMe storage interface and the current instance does not. To access NVMe volumes for the recommended instance type, you will need to install or upgrade the NVMe driver. For more information, see Networking and storage features and Amazon EBS and NVMe on Linux instances in the Amazon EC2 User Guide for Linux , or Networking and storage features and Amazon EBS and NVMe on Windows instances in the Amazon EC2 User Guide for Windows .
InstanceStoreAvailability — The recommended instance type does not support instance store volumes and the current instance does. Before migrating, you might need to back up the data on your instance store volumes if you want to preserve them. For more information, see How do I back up an instance store volume on my Amazon EC2 instance to Amazon EBS? in the Amazon Web Services Premium Support Knowledge Base . For more information, see Networking and storage features and Amazon EC2 instance store in the Amazon EC2 User Guide for Linux , or see Networking and storage features and Amazon EC2 instance store in the Amazon EC2 User Guide for Windows .
VirtualizationType — The recommended instance type uses the hardware virtual machine (HVM) virtualization type and the current instance uses the paravirtual (PV) virtualization type. For more information about the differences between these virtualization types, see Linux AMI virtualization types in the Amazon EC2 User Guide for Linux , or Windows AMI virtualization types in the Amazon EC2 User Guide for Windows .
Architecture — The CPU architecture between the recommended instance type and the current instance is different. For example, the recommended instance type might use an Arm CPU architecture and the current instance type might use a different one, such as x86. Before migrating, you should consider recompiling the software on your instance for the new architecture. Alternatively, you might switch to an Amazon Machine Image (AMI) that supports the new architecture. For more information about the CPU architecture for each instance type, see Amazon EC2 Instance Types.
(string) --
performanceRisk (float) --
The performance risk of the instance recommendation option.
Performance risk indicates the likelihood of the recommended instance type not meeting the resource needs of your workload. Compute Optimizer calculates an individual performance risk score for each specification of the recommended instance, including CPU, memory, EBS throughput, EBS IOPS, disk throughput, disk IOPS, network throughput, and network PPS. The performance risk of the recommended instance is calculated as the maximum performance risk score across the analyzed resource specifications.
The value ranges from 0 - 4 , with 0 meaning that the recommended resource is predicted to always provide enough hardware capability. The higher the performance risk is, the more likely you should validate whether the recommendation will meet the performance requirements of your workload before migrating your resource.
rank (integer) --
The rank of the instance recommendation option.
The top recommendation option is ranked as 1 .
savingsOpportunity (dict) --
An object that describes the savings opportunity for the instance recommendation option. Savings opportunity includes the estimated monthly savings amount and percentage.
savingsOpportunityPercentage (float) --
The estimated monthly savings possible as a percentage of monthly cost by adopting Compute Optimizer recommendations for a given resource.
estimatedMonthlySavings (dict) --
An object that describes the estimated monthly savings amount possible by adopting Compute Optimizer recommendations for a given resource. This is based on the On-Demand instance pricing..
currency (string) --
The currency of the estimated monthly savings.
value (float) --
The value of the estimated monthly savings.
migrationEffort (string) --
The level of effort required to migrate from the current instance type to the recommended instance type.
