# Cloud Computer

Vagon Computer is your personal cloud computer, accessible from any device, anywhere. Each computer is an isolated Windows machine running in the cloud with flexible performance options, persistent storage, and support for any application you install. You connect to it through a modern browser or through the Vagon Desktop Application for macOS and Windows over an encrypted real-time stream.

Use this documentation to create your computer, connect from different devices, manage files, optimize performance, and resolve common issues.

## When to Use Vagon Computer

Vagon Computer is designed to add capability to your setup without replacing your local machine. Consider using it when you need:

* **Additional processing power.** Run demanding software in the cloud while keeping your local device free for everyday work.
* **Mobility for heavy workloads.** Use a laptop, tablet, or mobile device to reach a powerful workstation instead of carrying one with you.
* **Flexible performance.** Switch between performance tiers as your project evolves. Start light during planning and scale up only when you need more power, while keeping the same files and setup.
* **A persistent cloud workstation.** Your files, installed software, and settings stay between sessions, so the computer behaves like a workstation you return to rather than a temporary environment.

You can change your performance option at any time without losing data. This is useful when a project moves from planning to rendering, or when you need a temporary boost for a specific task.

## How Vagon Computer Works

When you create a Vagon Computer, Vagon provisions an isolated Windows virtual machine in a cloud region near you. You connect to it from a browser or the Desktop Application, and your inputs and the streamed video both travel over an encrypted real-time channel. Files, installed apps, and settings persist on the machine between sessions.

## Security and Personal Data

Every Vagon Computer is an isolated virtual machine that no other user can access. It is your personal computer, hosted in the cloud so you can reach it from anywhere. Treat it like any workstation where you sign in to apps, store files, and run licensed software.

### How Vagon Protects Your Computer

* **Isolated virtual machines.** Each Vagon Computer runs on its own dedicated environment. Other users have no access to it.
* **Encrypted connections.** Sessions between your device and your Vagon Computer are always encrypted in transit.
* **Monitored infrastructure.** Vagon's technical team continually monitors infrastructure for vulnerabilities and keeps it updated.
