# Clusters in AWS CloudHSM
<a name="manage-clusters"></a>

A cluster is a collection of individual hardware security modules (HSM) that AWS CloudHSM keeps in sync. When you perform a task or operation on one HSM in a cluster, the other HSMs in that cluster are automatically kept up to date. 

You can manage your AWS CloudHSM clusters from the [AWS CloudHSM console](https://console.aws.amazon.com/cloudhsm/) or one of the [AWS SDKs or command line tools](https://aws.amazon.com/tools/). For more information, see the following topics.

To create a cluster, see [Getting started](getting-started.md).
