As enterprises embrace cloud-native architectures, managing secure and reliable communication between microservices becomes a critical challenge. Within the SAP Kyma ecosystem, which leverages Kubernetes for extensibility and integration, Service Mesh technology plays a vital role in enabling secure, observable, and resilient inter-service communication.
This article provides an overview of how Kyma’s built-in Service Mesh enhances secure service communication and helps organizations build robust SAP extensions on SAP Business Technology Platform (BTP).
A Service Mesh is an infrastructure layer that handles service-to-service communication in a microservices environment. It abstracts network communication, providing capabilities such as:
SAP Kyma integrates a Service Mesh based on Istio, a leading open-source service mesh framework. This integration provides a seamless way to secure, control, and monitor communications between microservices, functions, and APIs deployed in Kyma.
Key components include:
When deploying applications or functions in Kyma, enable automatic Envoy sidecar injection so that each service has the necessary proxy for mesh communication.
Configure Istio authentication and authorization policies to enforce mTLS and restrict communication between services based on business requirements.
Create routing rules for A/B testing or gradual rollouts to direct traffic intelligently and ensure smooth updates.
Use Kyma’s observability tools or integrate with Prometheus and Grafana to monitor service communication metrics and logs.
Kyma’s Service Mesh provides a robust foundation for secure, observable, and resilient communication between microservices in SAP’s cloud-native environment. By leveraging mutual TLS encryption, fine-grained access control, and powerful traffic management capabilities, organizations can build trustworthy SAP extensions that meet enterprise-grade security and reliability standards.
Mastering Kyma’s Service Mesh enables businesses to confidently scale their microservices architectures on SAP BTP, unlocking agility without compromising on security.
