Gateway API Workload Exposure
The concept name is missing or undefined, and the provided sources do not contain enough detail to identify and define a specific SAP developer concept beyond a general reference to Gateway API usage in SAP BTP, Kyma Runtime. Based on the available sources, a best-effort definition would be: Gateway API is a Kubernetes-native API used in SAP BTP, Kyma Runtime to expose workloads running in the cluster. Developers use it to configure and manage external access to their services and applications deployed on Kyma Runtime.

Prerequisites
- Concept Kyma Workload Exposure The concept name was not provided, but based on the sources, this appears to describe **APIRules** in SAP BTP, Kyma Runtime. An APIRule is a Kyma resource that developers use to [expose and secure workloads](https://help.sap.com/docs/btp/sap-business-technology-platform/19e332b59c084a928d4117b1f0d53d9b?locale=en-US&state=PRODUCTION&version=Cloud) running in a Kyma cluster. Developers can configure APIRules to control access to their services, including integrating external authorizers such as [oauth2-proxy for Authorization Code Flow](https://help.sap.com/docs/btp/sap-business-technology-platform/f2e9bf2be2714186b4231decd62a160b?locale=en-US&state=PRODUCTION&version=Cloud) to authenticate and authorize incoming requests.
- Concept Kubeconfig File Management and kubectl Access
- Concept Istio Module on Kyma The concept name was not provided (marked as "undefined"), and the supplied source snippets do not contain enough shared, focused content to define a single, specific SAP developer concept. The sources touch on distinct topics — reverting Istio module deletion, managing network policies, and exposing workloads via Gateway API in SAP BTP, Kyma Runtime — without a clear unifying concept to define. A valid concept name is required to produce an accurate, grounded definition.
