No. Due to the overhead our systems take, we regret that we can't keep freely connected clusters forever. You will be notified at 6 months after registration and you will have the opportunity to convert to a paid plan and avoid suspension of your cluster.
A resource is any cloud-native entity that gets scanned against available policies, such as a Kubernetes deployment, a cluster role, PVC, etc. The resource count is not impacted by the number of replicas or run-time objects. For example, we will count a Kubernetes Deployment as one entity even if creates 10 ReplicaSets at run-time.
There are certain approaches to Kubernetes that are just becoming a standard. Implement Liveness probes; implement Readiness Probes; set reasonable limits and requests, etc. At the entry price level, Magalix will help you ensure Best Practices.
