# Supported EC2 instance types using Terraform

Identify supported Amazon EC2 instance types for WEKA Terraform deployments.

## Backend EC2 instances

The following EC2 instance models can operate as **backend**, **client,** or **converged** instances. The default EC2 instance model for backends is **i3en.2xlarge**.

<table><thead><tr><th width="237">EC2 instance type</th><th>Supported instances</th></tr></thead><tbody><tr><td>i8ge</td><td>i8ge.2xlarge, i8ge.3xlarge, i8ge.6xlarge, i8ge.12xlarge, i8ge.18xlarge, i8ge.24xlarge, i8ge.48xlarge</td></tr><tr><td>I3en</td><td>i3en.2xlarge, i3en.3xlarge, i3en.6xlarge, i3en.12xlarge, i3en.24xlarge</td></tr></tbody></table>

{% hint style="info" %}
Deployment on i8ge instance types supports POSIX and S3 protocols. In cloud deployments, SMB and NFS do not run on backend instances. Deploy them on dedicated protocol gateways, as described below. For requirements, see [Additional protocol containers](/additional-protocols/additional-protocols-overview.md).
{% endhint %}

### Protocol gateway EC2 instances <a href="#protocol-gateway-ec2-instances" id="protocol-gateway-ec2-instances"></a>

The Terraform module deploys protocol gateways as separate instances from the backend cluster. The default EC2 instance model for NFS, SMB, and S3 protocol gateways is `c5n.2xlarge`. To use a different model, set the relevant variable in the `main.tf` file.

<table><thead><tr><th width="189.83984375">Protocol</th><th>Terraform variable</th></tr></thead><tbody><tr><td>NFS</td><td><code>nfs_protocol_gateway_instance_type</code></td></tr><tr><td>SMB</td><td><code>smb_protocol_gateway_instance_type</code></td></tr><tr><td>S3</td><td><code>s3_protocol_gateway_instance_type</code></td></tr></tbody></table>

## Client EC2 instances

The following EC2 instance models can operate as **client** instances. The default EC2 instance model for clients is **c5.2xlarge**.

{% hint style="info" %}

* Support for WEKA client over UDP mode is extended to any Intel or AMD CPU-based instance type, provided that the VM type meets the resource requirements specified in the [Prerequisites and compatibility](/5.1/planning-and-installation/prerequisites-and-compatibility.md) topic.
* Any backend instance can also be a client instance.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.weka.io/5.1/planning-and-installation/aws/supported-ec2-instance-types.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
