+### EKS
+
+Create an EKS cluster of desired benchmarking settings (region, instance types). If comparing against Constellation clusters with CVM instances, make sure to select the matching instance type on EKS.
+For example ([AWS documentation](https://repost.aws/de/knowledge-center/eks-persistent-storage)):
+
+```bash
+account_id=`aws sts get-caller-identity --query Account --output text`
+region="us-east-2"
+# create cluster
+eksctl create cluster --name benchmark --region $region --version 1.27  --node-type m6a.xlarge --node-volume-type gp3 --node-volume-size 30 --nodes 2
+# https://repost.aws/de/knowledge-center/eks-persistent-storage
+eksctl utils associate-iam-oidc-provider --region=$region --cluster=benchmark --approve
+oidc_id=$(aws eks describe-cluster --name $cluster_name --query "cluster.identity.oidc.issuer" --output text | cut -d '/' -f 5)
+sed "s/OIDCID/$oidc_id/g; s/ACCOUNTID/$account_id/g; s/REGION/$region/g" aws-ebs-csi-driver-trust-policy.json > trust-policy.json
+aws iam update-assume-role-policy --role-name AmazonEKS_EBS_CSI_Driver_Benchmark --policy-document file://"trust-policy.json"
+aws eks create-addon \
+ --cluster-name benchmark \
+ --addon-name aws-ebs-csi-driver \
+ --service-account-role-arn arn:aws:iam::$account_id:role/AmazonEKS_EBS_CSI_Driver_Benchmark
+```
+
+Once the cluster is ready, set up managing access via `kubectl` and take the benchmark:
+```bash
