 ## Kyma and SAP BTP, Kyma runtime
 
-There's a difference between the open-source Kyma project and SAP BTP, Kyma runtime (SKR). SKR is a bundle of a Kubernetes cluster powered by Gardener and Kyma modules provided as a managed service. All the components are regularly updated, and the availability is monitored and guaranteed by Service-Level Agreement (SLA). SKR is also preconfigured to easily connect to other SAP services and systems. Using SKR, you can face some limitations in configuring Kyma components because some settings are managed centrally and overwrite user changes. But still, you get the admin access to the cluster, that is, the **cluster-admin** role. If you use Kyma open-source components, you have more control and flexibility over installation, configuration, and upgrade processes but more operations-related responsibilities.
