SAP Kyma is a cloud-native application runtime that empowers developers to build, extend, and operate enterprise-grade applications in a Kubernetes environment. One of the key benefits of Kyma is its ability to handle dynamic workloads efficiently through robust resource management and scaling capabilities. Proper management of resources and scaling ensures that applications run smoothly, perform optimally, and cost-effectively meet business demands.
This article explores the essential concepts and best practices for managing resources and scaling applications in SAP Kyma.
Since Kyma runs on Kubernetes, it inherits Kubernetes’ resource management features, allowing fine-grained control over compute and memory usage for microservices and serverless functions.
Setting appropriate requests and limits ensures that applications have enough resources to operate without wasting cluster capacity.
Kubernetes assigns pods a QoS class based on their resource settings:
Kyma workloads should generally avoid the Best Effort class to ensure stable performance.
Scaling is the process of adjusting the number of running instances (pods) of an application to handle varying workloads.
Kyma leverages Kubernetes’ Horizontal Pod Autoscaler to automatically scale microservices and functions based on metrics such as CPU utilization or custom application metrics.
Kyma’s serverless framework, based on Kubernetes’ Knative, supports automatic scaling of functions to zero when idle, saving resources when functions are not in use.
Analyze application performance and set resource values that reflect actual usage to avoid overprovisioning or resource starvation.
Configure autoscalers to use meaningful metrics, such as CPU, memory, or custom business KPIs, for effective scaling decisions.
Leverage Kyma’s monitoring tools like Prometheus and Grafana to visualize resource consumption and scaling behavior.
Develop microservices and functions statelessly to support smooth horizontal scaling without complex session management.
For serverless functions, minimize cold start latency by optimizing container images and initialization logic.
Control the overall resource usage per namespace to prevent noisy neighbors and ensure fair resource allocation.
Managing resources and scaling applications effectively in SAP Kyma is crucial to delivering reliable, responsive, and cost-efficient cloud-native solutions. By leveraging Kubernetes’ resource management features, Horizontal Pod Autoscaler, and serverless capabilities, Kyma enables enterprises to build scalable SAP extensions and applications that adapt dynamically to business needs.
Following best practices in resource allocation, autoscaling, and monitoring ensures your Kyma workloads perform optimally while maintaining operational efficiency.
