We have been running an Ark Survival Evolved dedicated server for a while, and it has been a blast. We had up to 12 people playing on it, most of them friends (and some parents) of our kids.
We originally hosted the server on an Amazon Web Services instance, but recently moved it to Google’s managed Kubernetes service GKE. It works great and the deployment was very easy. If you want to do the same, below is how it works.
