# Best practices
<a name="best-practices"></a>

Follow these best practices when you set up a Red Hat OpenShift cluster on AWS:
+ List all prerequisites and make sure the installation program is set up correctly. 
+ Review security guidelines. For example, you might consider [removing the default cluster administrator](https://docs.openshift.com/container-platform/4.7/authentication/remove-kubeadmin.html) after installation.
+ Check the compatibility of all command-line tools, including OpenShift CLI (`oc`), Kubernetes command line tool (`kubectl`), AWS CLI, and `rosa` CLI.
+ Consider [rotating all credentials](https://docs.openshift.com/container-platform/4.7/post_installation_configuration/cluster-tasks.html#post-install-rotate-remove-cloud-creds).
