Select the type of hardware architecture on which your instance will be running:

* Choose an OS template, a volume, a snapshot, a custom <a href="https://gcore.com/docs/cloud/images/upload-an-image-to-the-storage" target="_blank">image</a>, or a template from the marketplace.
* (for a Linux instance) Remember the login from the **For login to OS** field to connect to your instance on Linux OS via SSH from another Linux device. For details, refer to the article: <a href="https://gcore.com/docs/cloud/virtual-instances/connect/connect-to-your-instance-via-ssh" target="_blank">Connect to your instance via SSH</a>.
- **x86-64**: This architecture is known for its broad compatibility with Linux operating systems and Windows distributions. It is commonly used in general purpose computing applications.
- **ARM**: ARM architecture is designed for energy efficiency and low power consumption, which also supports strong performance, making it ideal for high-performance computing tasks. However, ARM instances are compatible with fewer OS distributions.

**Important!** If you want to connect to a Linux instance from a Windows device, use a special application such as <a href="https://putty.org" target="_blank">PuTTY</a>.

4. For **Type**, choose the configuration.
Your choice of hardware architecture will affect the available OS options and instance flavors. Choose an OS distribution, a volume, a snapshot, a custom image, or a template from the marketplace.
