In today’s enterprise landscape, leveraging multiple cloud providers is a strategic choice to increase resilience, avoid vendor lock-in, and optimize costs. For SAP customers extending their SAP applications via cloud-native technologies, managing deployments across different cloud environments can be complex.
SAP Kyma, an open-source Kubernetes-based runtime available on SAP Business Technology Platform (BTP), offers a consistent and powerful way to build, deploy, and manage applications across multi-cloud environments. This article explores how SAP Kyma supports multi-cloud deployments and the best practices to manage them effectively.
Multi-cloud refers to the use of two or more cloud services from different providers such as AWS, Azure, Google Cloud, and SAP BTP Kyma Runtime. This strategy helps businesses:
Kyma is built on Kubernetes, which is supported natively across all major cloud providers. This makes Kyma applications portable:
Kyma uses Istio-based service mesh and an API Gateway, which provide:
Kyma supports event-driven architectures using SAP Event Mesh or NATS. This enables asynchronous communication across services hosted in different cloud environments, maintaining loose coupling and scalability.
Manage Kubernetes manifests and Kyma resources declaratively in Git repositories. Use tools like ArgoCD or Flux for automated sync and drift detection across clusters.
Implement centralized observability tools (e.g., Prometheus, Grafana, Loki) that aggregate metrics and logs from all cloud clusters into a single pane of glass.
Use tools like HashiCorp Vault, Kubernetes External Secrets, or SAP BTP’s secret management capabilities to synchronize secrets safely across clouds.
Imagine a scenario where:
Kyma’s consistent Kubernetes-based architecture allows these microservices to communicate via secure APIs and events, providing a seamless experience to end-users.
| Challenge | Kyma Solution |
|---|---|
| Cluster management | Centralized tools and Kyma CLI |
| API consistency | API Gateway with APIRules |
| Security across clouds | Istio service mesh and OAuth2 support |
| Networking complexity | Service mesh, VPN support |
| Observability across clouds | Unified Prometheus, Grafana, Loki dashboards |
Managing multi-cloud deployments is becoming a reality for SAP customers looking to build resilient, flexible, and scalable extensions. SAP Kyma leverages Kubernetes’ universality and augments it with enterprise-grade tooling to simplify deployment, security, and observability across clouds.
By adopting Kyma, organizations can confidently extend SAP solutions in multi-cloud architectures while maintaining operational consistency and reducing complexity.
