# Infrastructure
<important>
  The Applications UI Infrastructure functionality is in beta and is subject to change. The design and code is less mature than official generally available features and is being provided as-is with no warranties.
</important>

The **Infrastructure** tab provides information about the containers, pods, and hosts that the selected service is linked to.
- **Pods**: Uses the `kubernetes.pod.name` from the [APM metrics data streams](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5739/solutions/observability/apm/metrics).
- **Containers**: Uses the `container.id` from the [APM metrics data streams](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5739/solutions/observability/apm/metrics).
- **Hosts**: If the application is containerized—if the APM metrics documents include `container.id`—the `host.name` is used from the infrastructure data streams (filtered by `container.id`). If not, `host.hostname` is used from the APM metrics data streams.

IT ops and software reliability engineers (SREs) can use this tab to quickly find a service’s underlying infrastructure resources when debugging a problem. Knowing what infrastructure is related to a service allows you to remediate issues by restarting, killing hanging instances, changing configuration, rolling back deployments, scaling up, scaling out, and so on.

  **Why is the infrastructure tab empty?**If there is no data in the Application UI’s infrastructure tab for a selected service, you can read more about why this happens and how to fix it in the [troubleshooting docs](/elastic/docs-content/pull/5739/troubleshoot/observability/apm/common-problems#troubleshooting-apm-infra-data).
