 Provisioning and operating an SAP Cloud Application Programming Model application on a Kubernetes cluster requires the deployment of various components in addition to the CAP application server (see [a list of typical components](./cap-application-components.md)). Some of these components can be created at the time of system provisioning, while others need to be created (or updated) at different points during the lifecycle of the application (DAY 2 operational tasks).

   Enhancing Domain Management with CAP Operator

 The CAP Operator has introduced a pivotal update in domain management, transitioning from the deprecated `domains` section in `CAPApplication` resources to the more versatile `domainRefs`. This shift allows users to reference [`Domain`](../resources/domain) or [`ClusterDomain`](../resources/clusterdomain) resources, offering enhanced control over CAP applications' networking behaviour, including TLS handling, ingress routing, and DNS setup.
