Multi-Cloud Security Considerations

Multi-Cloud Security Considerations

Organizations operating Kubernetes across multiple cloud providers face unique security challenges. Consistency in security controls across different platforms requires abstraction layers and common tooling. While each cloud provider offers unique security features, core Kubernetes security principles remain constant, enabling portable security strategies.

Identity federation across clouds enables consistent authentication and authorization. Standards like SAML and OIDC enable identity providers to work across cloud boundaries. Service mesh identity systems like SPIFFE provide cloud-agnostic workload identity. These approaches enable zero-trust architectures spanning multiple cloud providers.

Unified policy management across clouds requires policy-as-code approaches. Tools like Open Policy Agent, Kyverno, or cloud-agnostic admission controllers enable consistent policy enforcement regardless of the underlying platform. GitOps workflows ensure policy synchronization across all clusters while maintaining audit trails.
