# Create an Instance

## Prerequisites

A VPC network must already be created.

For set up instructions, refer to the VPC Private Network guide.

## Configuration

### Payment Type

Determines billing model and resource lifecycle behavior.

| Payment Model     | Introduction                                                            |
| ----------------- | ----------------------------------------------------------------------- |
| **Subscription**  | Pay upfront. Terms range from 1 to 24 months.                           |
| **Pay-As-You-Go** | Pay after usage. Billed hourly. Supports on-demand scaling and release. |

### Region

* Specifies the geographic location of the data center.
* Impacts network latency—choose the region closest to your users.
* Cannot be modified after instance creation.

### VPC Network

* Select an existing VPC.
* An internal IP address is automatically assigned from the VPC’s subnet.

### Instance Specification and OS Image

* Instance Type defines compute resources (e.g., ces.g20-3.8xlarge = 192 vCPUs, 2048 GiB memory, 8× NVIDIA H100 80GB SXM GPUs).
* OS Image provides the base operating system. Example:
* Community Image: Ubuntu 22.04

### Additional Options (Optional)

* Install Cloud Assistant (enabled by default)

  Required for platform-managed maintenance and GPFS integration.

* Install Cloud Monitoring (enabled by default)

  Enables real-time performance monitoring and alerting.

* Enable Mounting GPFS Storage Devices (enabled by default)

  Allows the instance to mount GPFS storage volumes.

## Procedure

1. Navigate to the Compute Engine management console.
2. Click Create Instance.
3. Configure the following parameters:
   * Payment Type
   * Region
   * Instance Type
   * OS Image
   * (Optional) Additional features (e.g., Cloud Assistant, Cloud Monitoring, GPFS support)
4. Review all settings. Once confirmed, click Confirm Order.

## Expected result

Instance provisioning typically takes 20–30 minutes. Monitor the instance list for status updates. Creation is complete when the status changes to Running.
