# Node Groups Recommendations

The Node Groups tab within the Cluster Analysis page provides recommendations for optimizing your Kubernetes node pools. This tab helps you identify opportunities to select more cost-effective instance types while maintaining the capacity your workloads require.

## Supported Autoscalers

Akamas Insights supports node group recommendations for clusters using:

* **Kubernetes Cluster Autoscaler** - The standard autoscaler for Kubernetes clusters;
* **Karpenter** - A flexible, high-performance node provisioner.

## How Node Groups Are Identified

Akamas Insights identifies node groups by reading Kubernetes node labels. The platform automatically detects the appropriate label based on your cloud provider:

* **EKS**: `eks.amazonaws.com/nodegroup`
* **GKE**: `cloud.google.com/gke-nodepool`
* **AKS**: `agentpool`
* **Karpenter**: `karpenter.k8s.aws/instance-family` and related labels

Nodes without the expected label are grouped as "Unlabeled Nodes" and can still receive recommendations. You can also select a custom label if your environment uses non-standard node pool identification.

## Node Groups Analysis

The Node groups tab provides recommendations for Kubernetes cluster autoscaler configuration:

**Node Pool Configuration**:

* Current node pool sizes;
* Recommended minimum and maximum nodes;
* Recommended instance types;
* Cost implications of changes.

**Autoscaler Settings**:

* Scale-up and scale-down thresholds;
* Resource utilization targets;
* Buffer capacity recommendations.

{% hint style="warning" %}
Node groups recommendations require additional cluster autoscaler integration and may not be available in all deployments.
