# Create a Elastic Compute Service (ECS) - General Deployment Model

## Here are the ECS Deployment Steps

1. **Click on "Computing Power" on the left side Menu**

5. **Select OS**

{% hint style="info" %}
We have different types of OS. For Microsoft Windows, our platform takes care of the OS deployment only, and customers will need to purchase the license key from Microsoft directly in order to activate the full features.
{% endhint %}

{% hint style="success" %}
**Custom OS Options**:

1. **Custom Image Import**:
   * Customers can provide their custom OS image, which will be uploaded and imported into the system.
   * VMs can then be created based on the imported image.

2. **Custom VM Configuration**:
   * A VM can be created, configured, and then converted into a **custom image** for future use.
     {% endhint %}

3. **Choose Authentication Method**
   1. Password
   2. SSH Key ([SSH Key creation](/a-fieldtech-docs/compute-power/interactive-blocks.md#ssh-key))

7. **Select Security Group (Security Group Creation)**

8. **Select Bandwidth Billing Mode**

<div align="left"><figure><img src="/files/DLJ4056Q8PmPHw5mLzOD" alt=""><figcaption></figcaption></figure></div>

{% hint style="info" %}
In general use cases, the **"Global"** option is the default for internet access. However, for some regions, we have enabled cross-region low-latency bandwidth—for example, Hong Kong has the **CN2 (Premium China internet access option)**.

Please reach out to **<consolesupport@a-fieldtech.com>** if you have specific internet requirements.
{% endhint %}

9. **Select the Bandwidth**&#x20;

<div align="left"><figure><img src="/files/v5u6wTl0muWJRTTqUQc5" alt=""><figcaption></figcaption></figure></div>

{% hint style="info" %}
Bandwidth pricing is dynamic; it depends on the location you select. However, you will see the cost per Mbps when you deploy the server.
{% endhint %}

10. &#x20;**Assign Additional Public IPv4 (Optional)**

<div align="left"><figure><img src="/files/mVBxqOVWapzvE6PicTaB" alt=""><figcaption></figcaption></figure></div>

{% hint style="info" %}
You can attach up to 64 Public IPv4 into a single server, but if your server required more than 64 IP addresses per Host. Please see the[ Network section](/a-fieldtech-docs/network/create-a-cidr-block.md).
{% endhint %}

### Confirm The Configuration

This is the final stage. The ECS is flexible, and our pay-as-you-go model supports daily billing.

### Server Status

After confirmation, within a couple of minutes, you will be able to check your server status on the **homepage** [**dashboard**](/a-fieldtech-docs/getting-started/publish-your-docs.md) or the **Elastic Compute Service** page.
