 It is possible to use Cluster Autoscaler with a [mixed instances policy](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-autoscaling-autoscalinggroup-mixedinstancespolicy.html), to enable diversification across on-demand and Spot Instances, of multiple instance types in a single ASG. When using Spot Instances, this increases the likelihood of successfully launching a Spot Instance to add the desired capacity to the cluster versus a single instance type, which may be in short supply.
 
-Note that the instance types should have the same amount of RAM and number of CPU cores, since this is fundamental to CA's scaling calculations. Using mismatched instances types can produce unintended results, See an example below.

 Additionally, there are other factors which affect scaling, such as node labels. If you are currently using `nodeSelector` with the [beta.kubernetes.io/instance-type](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#interlude-built-in-node-labels) label, you will need to apply a common propagating label to the ASG and use that instead, since the instance-type label can no longer be relied upon. One may also use auto-generated tags such as `aws:cloudformation:stack-name` for this purpose. [Node affinity and anti-affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity) are not affected in the same way, since these selectors natively accept multiple values; one must add all the configured instances types to the list of values, for example:

 * Create an ASG with a MixedInstancesPolicy that refers to the newly-created LT.
 * Set LaunchTemplateOverrides to include the 'base' instance type r5.2xlarge and suitable alternatives, e.g. r5d.2xlarge, i3.2xlarge, r5a.2xlarge and r5ad.2xlarge. Differing processor types and speeds should be evaluated depending on your use-case(s).

 * For the same workload or for the generic capacity in your cluster, you can also create more node groups with a vCPU/Mem ratio that is a good fit for your workloads, but from different instance sizes. For example:
 Node group 1: m5.xlarge, m5a.xlarge, m5d.xlarge, m5ad.xlarge, m4.xlarge. 
 Node group 2: m5.2xlarge, m5a.2xlarge, m5d.2xlarge, m5ad.2xlarge, m4.2xlarge.
