the platform uses aws to create following resources : vpc, subnets, security groups, ec2 (spot ), s3
after you launch the scenarios the platform will create all the necessary resources and give access to k8s clusters.
to create clusters the platform uses kubeadm
you can easily add your own scenario using the already existing terraform module k8s_self_managment
k8s_self_managment module supports versions:

k8s version  : [ 1.21 , 1.34 ]   https://kubernetes.io/releases/
Rintime :
    docker                   [1.21 , 1.23]
