Usage and Benefits

How is KubeSlice useful to me?

KubeSlice creates a flat, secure virtual network overlay for streamlined data distribution and communication between distributed workloads. It enables multi-tenancy and reduces deployment time, complexity, and costs for multi-cloud, hybrid cloud, and edge environments. KubeSlice seamlessly integrates with the Kubernetes ecosystem.

How do I use KubeSlice to onboard applications?

KubeSlice supports slice creation. A slice can be connected to worker clusters, and applications from those connected clusters can be onboarded onto the slice. To learn more, see onboarding applications.

How do I distribute my applications across clusters?

You can onboard applications from your cluster onto a slice by onboarding namespaces and create a service export to distribute applications across clusters. The other clusters must also be part of that slice. To learn more, see Service Export.
