Compute optimization

Prev Next

This section describes the Kompass compute optimization solutions:

  • Headroom reduction: Cut costs by reducing overallocation and ensuring application availability, while still delivering on your SLA.

  • Pod rightsizing: Cut costs by matching Pod resources to real-time usage at the container level—no restarts or manual tuning—while still delivering on your SLA.

  • Adaptive Pod placement: Cut costs by optimizing Pod placement to increase the likelihood of autoscaler-driven node scale-down.

Manage EKS clusters

To see and manage EKS clusters, be sure that you’ve integrated an AWS account for Kompass use with EKS permissions. For more information, see Integrate and onboard an AWS account with Zesty.

Compute solutions supported environments and limitations

Headroom reduction supports these environments:

Supported

Environment

AWS Elastic Kubernetes Service (EKS), v1.28 or later. From v1.33, in-place Pod vertical scaling is supported.

Resource provisioning

  • Karpenter, v1.0 or later

    Spot management is supported only on clusters where Karpenter is enabled.

  • Cluster Autoscaler, v1.0 or later

Cluster

IAM role for Service Accounts (IRSA)

Autoscaling

HPA, KEDA

Headroom reduction cannot be applied to:

  • workloads linked to node pools that have only GPU instances configured

  • workloads linked to node pools that have a Bottlerocket image configured

  • workloads where Pod rightsizing is applied

Pod rightsizing and Adaptive Pod placement support these environments:

Supported

Environment

AWS Elastic Kubernetes Service (EKS), v1.28 or later. From v1.33, in-place Pod vertical scaling is supported.

Cluster

IAM role for Service Accounts (IRSA)

Workload types

Deployment, StatefulSet, DaemonSet, Argo Rollouts (canary or blue-green strategies)

Pod rightsizing generates recommendations only for the resources that have requests configured: CPU, memory, or both.

Pod rightsizing cannot be applied to:

  • workloads where the Headroom reduction solution is applied

  • workloads of these types: Jobs, cronjobs, or Replicasets
