# Bare Metal/VM Deployment Models

For bare-metal and VM based environments, a number of cluster configurations are supported. Some typical configurations are described below.

* * *

## Dedicated Single Master

In this configuration, the cluster is initially provisioned with two nodes i.e. "one" dedicated master node and "one worker node". Since the master is a dedicated master, user workloads will not be scheduled on this node. Additional master and worker nodes can be added/removed from this cluster anytime after it is provisioned.

## Converged Single Master

In this configuration, the cluster is initially provisioned with one node. i.e. "one" master node that also has a worker node role. Since this is a converged master, user workloads can also be scheduled on the master node. Additional worker nodes can be added/removed from this cluster anytime after it is provisioned.

* * *

## Dedicated Multi Master

In this configuration, the cluster is initially provisioned with four nodes. i.e. "three" master nodes forming a highly available, resilient quorum and "one" worker node. Since this is a dedicated master configuration, user workloads cannot be scheduled on the master nodes. Additional worker nodes can be added/removed from this cluster anytime after it is provisioned.

## Converged Multi Master

In this configuration, the cluster is initially provisioned with four nodes. i.e. "three" master nodes forming a highly available, resilient quorum and "one" worker node. All three master nodes also have a worker role. Since this is a converged master configuration, user workloads can be scheduled on the master nodes as well. Additional worker nodes can be added/removed from this cluster anytime after it is provisioned.
