1.2. What is the difference between OpenShift Container Platform and OpenShift Dedicated?

Red Hat OpenShift Container Platform clusters are self-managed and run on-premises or on a cloud provider. OpenShift Dedicated clusters are managed by Red Hat and run on a cloud provider.

OpenShift Container Platform is a self-managed hybrid cloud platform. With OpenShift Container Platform, you can create your clusters on any private or public cloud or bare metal, using your own infrastructure.

Red Hat OpenShift Dedicated is a fully managed service for Red Hat OpenShift, which uses Amazon Web Services (AWS) or Google Cloud Platform. With OpenShift Dedicated, you can run your clusters on Red Hat’s managed cloud account, or on your own AWS or Google Cloud Platform (GCP) cloud provider account.

OpenShift Cluster Manager allows you to create and manage your OpenShift Container Platform and OpenShift Dedicated clusters from one dashboard.

1.3. Using OpenShift Cluster Manager with OpenShift Container Platform

OpenShift Cluster Manager provides a user interface to create OpenShift Container Platform clusters and subscribe the clusters to Red Hat for support.

OpenShift Cluster Manager provides the installer and instructions to create self-managed clusters on each supported environment for OpenShift Container Platform.

You can then view and manage your OpenShift Container Platform clusters in OpenShift Cluster Manager, or log into the OpenShift Container Platform web console to access and configure your clusters.

You can find information about the latest OpenShift Container Platform release versions available, as well as update channels for your clusters from the Releases menu in OpenShift Cluster Manager.

You can also gain insights about your clusters using integrated services within the Red Hat Hybrid Cloud Console such as Red Hat Insights Advisor, Subscriptions, and Cost Management.

1.4. Using OpenShift Cluster Manager with OpenShift Dedicated

OpenShift Cluster Manager provides a user interface to create, view and manage your OpenShift Dedicated clusters.

OpenShift Dedicated clusters are managed by Red Hat and are known as managed clusters. You can create OpenShift Dedicated clusters on AWS or Google Cloud Platform, using either Red Hat’s managed cloud account or your own cloud provider account. When using your own cloud provider account, this billing model is referred to as Customer Cloud Subscription (CCS) in OpenShift Cluster Manager.

1.5. Using OpenShift Cluster Manager with Red Hat OpenShift Service on AWS

OpenShift Cluster Manager provides a user interface to create, view and manage your Red Hat OpenShift Service on AWS (ROSA) clusters.

ROSA is a fully-managed OpenShift service, jointly managed and supported by Red Hat and Amazon Web Services (AWS). This service is procured directly from your AWS account. ROSA pricing is consumption based and is billed directly to your AWS account.

You can quickly deploy ROSA from OpenShift Cluster Manager or the rosa CLI. In OpenShift Cluster Manager, you can manage your ROSA cluster and any add-on services for the cluster.

1.6. Using OpenShift Cluster Manager with the Red Hat Hybrid Cloud Console

OpenShift Cluster Manager is integrated with other services hosted on the Red Hat Hybrid Cloud Console, which you can use to gain deeper understanding and manage your OpenShift clusters:

  • Insights Advisor for OpenShift Container Platform monitors the health of your OpenShift Container Platform clusters and helps you identify, prioritize, and resolve risks to service availability, fault tolerance, performance, and security.
  • Subscriptions allows you to monitor your usage and subscription information for your OpenShift clusters.
  • Cost management aggregates and displays the costs of your OpenShift deployment and infrastructure across bare-metal servers, virtual machines, private clouds and public cloud infrastructure, including AWS and Microsoft Azure.

You need a Red Hat account to access OpenShift Cluster Manager and the Red Hat Hybrid Cloud Console. You can then deploy an OpenShift cluster in OpenShift Cluster Manager.

For greater security, you can use two-factor authentication (2FA) to access OpenShift Cluster Manager and the Red Hat Hybrid Cloud Console. Two-factor authentication needs to be enabled in your Red Hat account to use 2FA to access OpenShift Cluster Manager. Organization Administrators can enable 2FA for all users in their organization, or individual users can configure 2FA for their own Red Hat account.

To enable two-factor authentication in your Red Hat account or learn more, see the Using Two-Factor Authentication guide.

1.7. Using add-on services on your OpenShift cloud services clusters

Add-ons are additional services that you can install to your existing Red Hat OpenShift Dedicated and Red Hat OpenShift Service on AWS (ROSA) clusters to enhance cluster capabilities.

You can install and manage add-on services from a cluster’s Add-ons tab in OpenShift Cluster Manager.

Depending on the add-on service, you may need additional Red Hat subscriptions or quota to use it. See the documentation for the add-on to learn more about the requirements and for instructions for using the add-on.
