= Understanding how {product-title} differs from {OCP}
|
|
|
|
{product-title} uses the same code base as {OCP} but is installed in an opinionated way to be optimized for performance, scalability, and security. {product-title} is a fully managed service; therefore, many of the {product-title} components and settings that you manually set up in {OCP} are set up for you by default.
|
|
|
|
Review the following differences between {product-title} and a standard installation of {OCP} on your own infrastructure:

|
|
|
|
|The customer installs and configures {OCP}.

|
{product-title} is installed through {cluster-manager-first} and in a standardized way that is optimized for performance, scalability, and security.
|
|
endif::openshift-dedicated[]
|
|
ifdef::openshift-rosa[]
|
|
{product-title} is installed through {cluster-manager-first} or the ROSA CLI (`rosa`) and in a standardized way that is optimized for performance, scalability, and security.
|
|

|
|
|
|
|Customers can choose their computing resources.
|
|
|
|
|
ifdef::openshift-dedicated[]
|
|
{product-title} is hosted and managed in a public cloud (Amazon Web Services or Google Cloud Platform) either owned by Red{nbsp}Hat or provided by the customer.
|
|
endif::openshift-dedicated[]
|
|
ifdef::openshift-rosa[]
|
|
{product-title} is hosted and managed in a public cloud (Amazon Web Services) provided by the customer.
|
|
endif::openshift-rosa[]
|
|
|
|
|Customers have top-level administrative access to the infrastructure.
|
|
|
|
|
ifdef::openshift-dedicated[]
|
|
Customers have a built-in administrator group (`dedicated-admin`), though the top-level administration access is available when cloud accounts are provided by the customer.

|
|
|Customers can use all supported features and configuration settings available in {OCP}.
|
|
|Some {OCP} features and configuration settings might not be available or changeable in {product-title}.
|
|
|
|
|You set up control plane components such as the API server and etcd on machines that get the `control` role. You can modify the control plane components, but are responsible for backing up, restoring, and making control plane data highly available.
|
|
|Red Hat sets up the control plane and manages the control plane components for you. The control plane is highly available.
|
|
|
|
|You are responsible for updating the underlying infrastructure for the control plane and worker nodes. You can use the OpenShift web console to update {OCP} versions.
|
|
|Red{nbsp}Hat automatically notifies the customer when updates are available. You can manually or automatically schedule updates in {cluster-manager}.
|
|
|
|
|Support is provided based on the terms of your Red Hat subscription or cloud provider.
|
|
|Engineered, operated, and supported by Red Hat with a 99.95% uptime SLA and 24x7 coverage. For details, see link:https://www.redhat.com/licenses/Appendix-4-Red-Hat-Online-Services-20230523.pdf[Red Hat Enterprise Agreement Appendix 4 (Online Subscription Services)].
