Install Multicluster

A service mesh or simply mesh is an infrastructure layer that enables managed, observable and secure communication between workload instances.

Service names combined with a namespace are unique within a mesh. In a multicluster mesh, for example, the bar service in the foo namespace in cluster-1 is considered the same service as the bar service in the foo namespace in cluster-2.

Since identities are shared within the service mesh, workload instances can authenticate communication with any other workload instance within the same service mesh.

A cluster is set of compute nodes that run containerized applications. Typically, the compute nodes comprising a cluster can reach each other directly. Clusters limit external access through rules or policies.

Multicluster is a deployment model that consists of a mesh with multiple clusters.
