Sailing Multi Cloud Traffic Management With Karmada

on YouTube ↗30m

" summary

Karmada claims to treat multi-cloud clusters like a single Kubernetes control plane by using a Karmada API server, control manager and scheduler and by offering 44 multi-cluster scheduling policies plus override policies for per-cluster images and storage. It integrates with Istio to push xDS to Envoy sidecars, enabling L7 features such as priority routing, cross-cloud failover and mTLS-encrypted east‑west traffic. It supports both flat vs different networks models (sidecar direct IPs or gateway SNI passthrough) and uses multi-cluster service APIs and a DNS proxy for discovery.
