Multicluster Installation

Configure an Istio mesh spanning multiple Kubernetes clusters.

Simplified Multicluster Install [Experimental]

Configure an Istio mesh spanning multiple Kubernetes clusters.

Replicated control planes

Install an Istio mesh across multiple Kubernetes clusters with replicated control plane instances.

Shared control plane (single-network)

Install an Istio mesh across multiple Kubernetes clusters with a shared control plane and VPN connectivity between clusters.

Shared control plane (multi-network)

Install an Istio mesh across multiple Kubernetes clusters using a shared control plane for disconnected cluster networks.

Note that these instructions are not mutually exclusive.In a large multicluster deployment, composed from more than two clusters,a combination of the approaches can be used. For example,two clusters might share a control plane while a third has its own.

Refer to the multicluster deployment modelconcept documentation for more information.
