# Configure gRPC Support

IONOS CLOUD Application Load Balancer: configure gRPC support for backend services

You can configure an ALB to support gRPC, a high-performance RPC framework using HTTP/2 for transport. The gRPC enables users to define service methods and messages in a language-agnostic way, making API creation straightforward across different platforms. Additionally, it supports advanced features such as load balancing, retries, and deadlines.

To configure gRPC follow these steps:

1. Create a Target Group. Follow the steps outlined in the [<mark style="color:blue;">Create Target Group</mark>](/cloud/network-services/application-load-balancer/how-tos/create-target-groups.md) guide.

Ensure you select **HTTP** as the protocol and **HTTP2** as the protocol version for gRPC support. It is recommended not to set any HTTP health checks for gRPC support.

#### Example target group request for gRPC support

```json
{
  “properties”: {
    “name”: “grpc-target-group”,
    “protocol”: “HTTP”,
    "protocolVersion": "HTTP2",
    “algorithm”: “ROUND_ROBIN”,
    “targets”: [
      {
        “ip”: “10.10.10.10”,
        “port”: 8000,
        “weight”: 1
      }
    ]
  }
}
```

2. Follow [<mark style="color:blue;">Set Up an Application Load Balancer</mark>](/cloud/network-services/application-load-balancer/how-tos/setup-alb.md) guide to complete configuring the load balancer for gRPC traffic.

{% hint style="success" %}
**Result:** ALB will now support gRPC traffic by handling HTTP/2 requests and enabling efficient gRPC communication.
{% endhint %}

## 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.ionos.com/cloud/network-services/application-load-balancer/how-tos/configure-grpc.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.
