In this section, you'll learn how to enable the Google Compute Engine (GCE) cloud provider for custom clusters in Rancher. A custom cluster is one in which Rancher installs Kubernetes on existing nodes.

### Using the Authorized Cluster Endpoint (ACE)
|

|
||||
An [Authorized Cluster Endpoint](../../../reference-guides/rancher-manager-architecture/communicating-with-downstream-user-clusters#4-authorized-cluster-endpoint) (ACE) provides access to the Kubernetes API of Rancher-provisioned RKE, RKE2, and K3s clusters. When enabled, the ACE adds a context to kubeconfig files generated for the cluster. The context uses a direct endpoint to the cluster, thereby bypassing Rancher. This reduces load on Rancher for cases where unmediated API access is acceptable or preferable. See [Authorized Cluster Endpoint](../../../reference-guides/rancher-manager-architecture/communicating-with-downstream-user-clusters#4-authorized-cluster-endpoint) for more information and configuration instructions.

The two main bottlenecks to [etcd performance](https://etcd.io/docs/v3.4/op-guide/performance/) are disk and network speed. Etcd should run on dedicated nodes with a fast network setup and with SSDs that have high input/output operations per second (IOPS).

It's best to run etcd on exactly three nodes, as adding more nodes will reduce operation speed. This may be counter-intuitive to common scaling approaches, but it's due to etcd's [replication mechanisms](https://etcd.io/docs/v3.5/faq/#what-is-maximum-cluster-size).
