 It is strongly recommended to use hosted infrastructure such as Amazon's EC2 or Google's GCE instead. When you create a cluster using RKE on an infrastructure provider, you can configure the cluster to create etcd snapshots as a backup. You can then [use RKE](https://rancher.com/docs/rke/latest/en/etcd-snapshots/) or [Rancher](../../pages-for-subheaders/backup-restore-and-disaster-recovery.md) to restore your cluster from one of these snapshots. In a hosted Kubernetes environment, this backup and restore functionality is not supported.

 It's important to follow K8s and etcd best practices when deploying your nodes, including disabling swap, double checking you have full network connectivity between all machines in the cluster, using unique hostnames, MAC addresses, and product_uuids for every node, checking that all correct ports are opened, and deploying with ssd backed etcd.  More details can be found in the [kubernetes docs](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/#before-you-begin) and [etcd's performance op guide](https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/performance.md)
