# Communicate with other workloads

This guide shows you how to communicate with other workloads inside the same environment or cluster via [*service discovery*](/workloads/application/explanations/expose.md#service-discovery).

## Prerequisites

- Your workload has [configured policies for *outbound traffic* to the target workload](/workloads/how-to/access-policies.md#outbound-access)
- The target workload has [configured policies for *inbound traffic* from your workload](/workloads/how-to/access-policies.md#inbound-access)

## Identify the target address

To identity the address of the workload we are communicating with, we need to know its `name` and what `namespace` its running in.

### Target exists in the same namespace

If the workload you are calling is in the same namespace, you can reach it by calling its name directly using HTTP like so:

```plaintext
http://<name>
```

### Target exists in another namespace

If the workload is running in another team's namespace, you need to specify the namespace as well:

```plaintext
http://<name>.<namespace>
```

## Call the address

Call the workload through its internal address using HTTP from your own workload:

```http
GET /resource HTTP/1.1

Host: <name>.<namespace>
```
