Istio Sidecar Proxy Injection
The concept name was not provided, but based on the sources, this definition covers Istio Service Mesh in SAP BTP, Kyma Runtime. Istio Service Mesh is a infrastructure layer used in SAP BTP, Kyma runtime that manages service-to-service communication through Istio sidecar proxies injected alongside workloads. Developers use it to secure traffic between services with mutual TLS (mTLS), expose workloads via TLS or mTLS Gateways, and control network policies using resources such as the Sidecar resource to minimize load and footprint. It also provides troubleshooting capabilities for issues such as connection refused errors or incompatible sidecar versions after module updates.

Prerequisites
- Concept Kubernetes Namespace Management The concept name was not provided (marked as "undefined"), and the available source snippets do not contain enough detail to construct a fully grounded, accurate definition for an unspecified concept. Only [S1] offers substantive content — describing **Kyma Dashboard** as a tool used to access various features and functionalities of [SAP BTP, Kyma runtime](https://help.sap.com/docs/btp/sap-business-technology-platform/482ae2f53fa64568af28ba1349f5836c?locale=en-US&state=PRODUCTION&version=Cloud) — while the remaining sources are tutorial titles without descriptive body text. Without a valid concept name, a reliable definition cannot be produced.
- 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.
- Concept Kyma Istio Service Mesh Module The concept name is not defined in the provided sources, so a precise definition cannot be grounded. Based on the available source snippets, the [Istio module](https://help.sap.com/docs/btp/sap-business-technology-platform/26ffe00c24574db58697992b93f397ac?locale=en-US&state=PRODUCTION&version=Cloud) is a [Kyma module](https://help.sap.com/docs/btp/sap-business-technology-platform/0dda141a58d54f29a860a4b3164bf4a9?locale=en-US&state=PRODUCTION&version=Cloud) that developers use to manage and configure the Istio service mesh within SAP BTP, Kyma Runtime. Using Kyma's modular approach, developers can install only the modules they need, and with the Istio module they can expose workloads via Istio VirtualService or Gateway API.
- Concept Kyma Environment The concept name was not provided, so a precise definition cannot be produced from the available sources. Based on the source snippets, the **Kyma environment** is a platform-as-a-service offering within [SAP Business Technology Platform (SAP BTP)](https://help.sap.com/docs/btp/sap-business-technology-platform/15547f7e7ecd47ee9fa052b0e18c7b0a?locale=en-US&state=PRODUCTION&version=Cloud) that allows developers to build, extend, and run applications and services. It supports the consumption of SAP BTP services and uses availability zones to provide resilience and high availability for workloads.
- Concept Kyma / Kubernetes Deployment The concept name was not provided, making it impossible to write a meaningful or accurate reference definition grounded in the supplied sources. Please provide the specific SAP developer concept to be defined.
