As enterprises move toward modern, scalable application architectures, the move from monolithic codebases to microservices becomes essential. SAP Kyma Runtime is the specific component of SAP BTP designed to support this transition. It is a fully managed Kubernetes-based environment that allows developers to extend SAP applications using serverless functions and microservices. Kyma provides a cloud-native way to build and run containerized applications, offering high scalability and flexibility.

Positioning Kyma within the SAP Business Suite ecosystem is critical for "side-by-side" extensibility. It allows developers to build specialized services—such as a custom loyalty engine or a unique logistics tracker—using their preferred programming languages and frameworks (like Node.js, Go, or Python) while maintaining a seamless connection to the SAP core. Kyma is particularly powerful for "event-driven" architectures; it can listen for events in SAP S/4HANA (like a "New Sales Order created" event) and instantly trigger a microservice to perform a specific action in a third-party system. This decouples the innovation layer from the stable core, allowing for rapid updates and deployments without risking the stability of the primary business processes.
