# Features and Benefits

## Features

* **Power operations:** Manage your Cloud GPU VMs with standard power operations, including stop, start, and restart capabilities.
* **STOP** deallocates the Compute unit of your instance and returns the GPUs, CPUs, and RAM to the hardware pool. **Block Storage** remains provisioned, allowing you to resume work after restarting the instance. Billing will be paused when you stop the Cloud GPU instance.

{% hint style="info" %}
**Note:** Deallocated resources may be used for other <code class="expression">space.vars.ionos\_cloud</code> users' workloads. Depending on availability, an instance may fail to start if all resources are currently in use.
{% endhint %}

* **START** provisions the Compute unit and allocates the GPUs, CPUs, and RAM as specified in your VM template configuration. The **Block Storage** volume is remounted to the VM instance, restoring access to your data and configurations. Billing for the instance will resume immediately.
* **REBOOT** executes a power cycle of your Cloud GPU instance. This operation does not deallocate resources, as the instance remains active. Billing is not paused during this operation.
* **Server configuration:** Provision servers using pre-configured templates with Cloud GPU VM specifications, or customize storage by attaching additional volumes that scale independently.
* **Operating system support:** Cloud GPU VMs currently support Linux-only virtual machines.
* **Auto availability zone:** Cloud GPU VMs deploy automatically across availability zones for optimal resource distribution.
* **Volume operations:** The <code class="expression">space.vars.ionos\_cloud</code> API and the DCD supports upscaling additional volumes and attaching or detaching volumes. The first connected volume (storage volume) cannot be detached or upscaled.
* **Availability:** It is currently available only in the **Frankfurt** `de/fra/2` data center.

## Benefits

* **Complete control and flexibility:** Create and delete your Cloud GPU VMs on demand, giving you full control over resource usage and costs while maintaining uninterrupted workflow management.
* **Reliable Linux-based infrastructure:** Leverage the stability and performance of Linux virtual machines, optimized for Cloud GPU VM workloads and available through a streamlined <code class="expression">space.vars.ionos\_cloud</code> API and through the DCD for efficient automation and integration.
* **Scalable storage architecture:** Expand your storage capacity on the fly by attaching additional volumes or increasing their size, allowing your infrastructure to grow seamlessly alongside your projects without downtime.
