A primary cluster is a [cluster](/docs/reference/glossary/#cluster) with a
|
|
[control plane](/docs/reference/glossary/#control-plane). A single
|
|
[mesh](/docs/reference/glossary/#service-mesh) can have more than
|
|
one primary cluster for HA or to reduce latency. Primary clusters can act as the
|
|
control plane for [remote clusters](/docs/reference/glossary/#remote-cluster).
