## What is a Cluster?

A cluster is a connected group of cloudSwXtches in a variety of the same or dispersed network locations – different Vnets, regions, clouds, subnets, data centers, etc. Additionally, a cluster is a way to group two or more connected cloudSwXtches together to act as one to gain network performance.

Learn more about a Cluster

- See [Monitor cloudSwXtch with wXcked Eye](/v2/docs/monitor-cloudswxtch-with-wxcked-eye) to learn more about monitoring cloudSwXtches, to understand existing capacity, and to know if you need to consider creating a cloudSwXtch cluster.
- See [wXcked Eye System Management/Clusters](/v2/docs/cluster-wxcked-eye) for cluster configuration.

## Clusters

A cluster is formed by linking cloudSwXtches so that they are eligible to receive and transmit multicast traffic to other cloudSwXtches in the same cluster. [wXcked Eye System Management Clusters](/v2/docs/cluster-wxcked-eye) allows a user to create a network of cloudSwXtches across Availability Zones, Regions, and On-Prem Networks to manage multicast traffic.

Clusters can also be used to segment multicast network traffic ensuring that the user has the opportunity to design their network down to what multicast flows to which cloudSwXtch within a cluster.

Also, a Cluster serves as a basic element to create an [HA array](/v2/docs/high-availability).

IMPORTANT

- A cloudSwXtch can only be a member of a single cluster.
