# Tenant Quotas, User Quotas and VM Leases

<code class="expression">space.vars.product\_name</code> enables you to apply limits or quotas for various resources at each tenant and user level, to ensure that no single tenant can use more than their entitled amount of resources. In addition, you can configure VM lease policy to control how long a virtual machine may exist.

{% hint style="info" %}
Note: User level quotas can be used for controlling individual users limits. User level quotas override tenant quotas for the respective users.
{% endhint %}

{% hint style="warning" %}
You must be an administrator to edit, create, and delete quotas and leases.

### Virtual Machine Lease Settings

A virtual machine lease controls how long a single virtual machine created by a user in a given tenant may exist, measured in days. Setting a virtual machine lease will cause any virtual machine created under the defined tenant to be **automatically deleted once the lease age is met.**
