Compute Optimizer doesn't generate EC2 rightsizing recommendations for Spot Instances. ## Supported Amazon EC2 Auto Scaling groups Compute Optimizer generates rightsizing and idle recommendations for Amazon EC2 Auto Scaling groups. This section outlines what Compute Optimizer supports for both types of recommendations. ### Rightsizing recommendations Compute Optimizer supports rightsizing recommendations for EC2 Auto Scaling groups that have the following: + Single EC2 instance types + Mixed EC2 instance types + One or multiple scaling policies based on CPU utilization: + Target tracking + Predictive scaling + Simple scaling + Step scaling + Scheduled scaling policies + No scaling policy **Note** Compute Optimizer doesn't support rightsizing recommendations for EC2 Auto Scaling groups that have the following: EC2 instance types that aren’t [supported by Compute Optimizer](https://docs.aws.amazon.com//compute-optimizer/latest/ug/supported-resources.html#supported-ec2-instances) Spot Instances Mixed instance types that contain any instances outside of the C, M, or R instance families Amazon ECS or Amazon EKS workloads Mixed instance types containing both AMD and Intel instances Mixed instance types using instance weights Mixed instance types containing both x86 and Graviton instances Mixed instance types containing instances on different platforms, such as Windows, SQL Server, and Linux ### Idle recommendations Compute Optimizer supports idle recommendations for EC2 Auto Scaling groups that use most of the [Supported Amazon EC2 instance types](#supported-ec2-instances).
