- DigitalOcean offers free clusters.

- Azure (still?) offers free clusters.

- GCP offers one free single-zone cluster.

If you need more than DO can offer in terms of compute instances, you can probably afford GKE/EKS, which is around 75$/month.

Running highly-available control plane (K8s masters & etcd) by yourself is NOT cheaper than using EKS.

To achive high availability, EKS runs 3 masters and 3 etcd instances, in different availability zones. Provisioning 3 t3.medium instances (4 GB of memory and 2 CPUs) would cost the same as a completely managed EKS.

Not to mention the manual work you need to setup, maintain and upgrade such instances.
