Shared cluster components
Shared cluster components provide underlying functionality for the IBM Cloud Pak® for Data control plane and services. Depending on the services that you plan to install or the features that you want to use in IBM Cloud Pak for Data, you might need to install one or more required components on your cluster.
Shared cluster components are different from end-user services, such as the Watson™ Studio or Watson Query services. Unlike typical services, end users do not interact directly with the shared cluster components.
Use the following information to determine whether you need to install any of these components on your cluster.

You are installing a service that relies on the common core services. | The common core services services are
installed once in a given Red Hat®
OpenShift®
project. Any services in the project that rely on the common core services can use the same installation. The
common core services are automatically installed by
the services that require them:
